106-719: Birmingham Canal Navigations ( BCN ) is a network of canals connecting Birmingham , Wolverhampton , and the eastern part of the Black Country . The BCN is connected to the rest of the English canal system at several junctions. It was owned and operated by the Birmingham Canal Navigation Company from 1767 to 1948. At its working peak, the BCN contained about 160 miles (257 km) of canals; today just over 100 miles (160 km) are navigable, and
212-547: A caisson of water in which boats float while being moved between two levels; and inclined planes where a caisson is hauled up a steep railway. To cross a stream, road or valley (where the delay caused by a flight of locks at either side would be unacceptable) the valley can be spanned by a navigable aqueduct – a famous example in Wales is the Pontcysyllte Aqueduct (now a UNESCO World Heritage Site ) across
318-510: A drainage divide atop a ridge , generally requiring an external water source above the highest elevation . The best-known example of such a canal is the Panama Canal . Many canals have been built at elevations, above valleys and other waterways. Canals with sources of water at a higher level can deliver water to a destination such as a city where water is needed. The Roman Empire 's aqueducts were such water supply canals. The term
424-415: A "cistern", or depressed area just downstream from the fall, to "cushion" the water by providing a deep pool for its kinetic energy to be diffused in. Vertical falls work for drops of up to 1.5 m in height, and for discharge of up to 15 cubic meters per second. The transport capacity of pack animals and carts is limited. A mule can carry an eighth-ton [250 pounds (113 kg)] maximum load over
530-597: A boat rally was held at Hawne Basin , a former Great Western Railway interchange, where tubes were moved from boats to trains. The railway had closed in 1967, and the basin had been unused since then, but thirty boats attended the rally, and the Combeswood Canal Trust developed plans for turning it into a marina. Part of the Lapal Tunnel was unearthed during the construction of the M5 motorway during
636-496: A canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as slack water levels , often just called levels . A canal can be called a navigation canal when it parallels a natural river and shares part of the latter's discharges and drainage basin , and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley . A canal can cut across
742-644: A cast-iron footbridge, built in 1858, still carries the towpath over the former entrance to the Two Locks Line. An embankment on the side of a hill carries the canal on to Blowers Green Lock, which is the deepest lock on the Birmingham Canal Navigations, as it replaced two earlier locks which were affected by subsidence. Nearby is a pumphouse, managed by the Dudley Canal Trust. At Park Head Junction, Line No. 2 turns off to
848-505: A collapse of the canal severed part of the loop. Having suffered from mining subsidence for years, the two-locks line was closed in March 1909 and later filled in. The line is now under a late 20th century industrial estate and only the junctions, towpath bridges and a few yards of watered but unnavigable canal remain. After repeated collapses, Lapal Tunnel was abandoned in June 1917 leaving
954-413: A combination of the three, depending on available water and available path: Smaller transportation canals can carry barges or narrowboats , while ship canals allow seagoing ships to travel to an inland port (e.g., Manchester Ship Canal ), or from one sea or ocean to another (e.g., Caledonian Canal , Panama Canal ). At their simplest, canals consist of a trench filled with water. Depending on
1060-705: A cutting and bridge when work began. The length of the canal was to be 10.8 miles (17.4 km), for which the working capital would be £90,000 with an additional £40,000 if required. John Snape carried out a survey and despite opposition from the Birmingham Canal, the Staffordshire and Worcestershire Canal and a contingent of iron foundries in Wolverhampton , an act of Parliament, the Selly Oak Canal Act 1793 ( 33 Geo. 3 . c. 121),
1166-549: A journey measured in days and weeks, though much more for shorter distances and periods with appropriate rest. Besides, carts need roads. Transport over water is much more efficient and cost-effective for large cargoes. The oldest known canals were irrigation canals, built in Mesopotamia c. 4000 BC , in what is now Iraq . The Indus Valley civilization of ancient India ( c. 3000 BC ) had sophisticated irrigation and storage systems developed, including

#17327731094201272-709: A new junction with the Worcester and Birmingham Canal to the recently reconstructed Harborne Lane bridge along the route of the former Dudley Canal. On 28 February 2016, following re-excavation of part of the Harborne Lane Wharf, a canoe paddled by a member of the Lapal Canal Trust, became the first vessel since 1953, to proceed along the part of the Eastern length of canal which runs through Selly Oak Park and part of which, remains "in water". It
1378-581: A rather low gradient for its time. The canal is still in use after renovation. In the Middle Ages , water transport was several times cheaper and faster than transport overland. Overland transport by animal drawn conveyances was used around settled areas, but unimproved roads required pack animal trains, usually of mules to carry any degree of mass, and while a mule could carry an eighth ton, it also needed teamsters to tend it and one man could only tend perhaps five mules, meaning overland bulk transport
1484-423: A scheme which used a steam pumping engine and stop locks at either end of the tunnel to create a flow which assisted the movement of the boats. This proved successful for it continued to be used until 1914 and Brewin was awarded plate worth £50 in recognition of his contribution. In 1838, a 400-yard (370 m) cut was made at Lodge Farm to divert the canal and make room for a storage reservoir and pumping engine and
1590-512: A short stretch navigable between Selly Oak and a brick works at California until 1953, after which it was drained and filled in. After a period of disuse following nationalisation in 1948, the first suggestions that the canal and others should be restored were made by the newly formed Inland Waterways Protection Society (IWPS) in 1959. However, the British Transport Commission presented their annual Bill in 1961, in which
1696-459: A uniform altitude. Other, generally later, canals took more direct routes requiring the use of various methods to deal with the change in level. Canals have various features to tackle the problem of water supply. In cases, like the Suez Canal, the canal is open to the sea. Where the canal is not at sea level, a number of approaches have been adopted. Taking water from existing rivers or springs
1802-422: Is a channel that cuts across a drainage divide , making a navigable channel connecting two different drainage basins . Both navigations and canals use engineered structures to improve navigation: Since they cut across drainage divides, canals are more difficult to construct and often need additional improvements, like viaducts and aqueducts to bridge waters over streams and roads, and ways to keep water in
1908-465: Is no mention of how this was achieved. The tunnel was also affected by subsidence from local coal mining and was regularly closed to allow repairs to be made. Working a loaded boat through the tunnel took about 4 hours and this caused congestion. Various ways were considered to alleviate this, including rope haulage in 1840, but the cost of £6,000 was deemed to be too expensive. Subsidence in the Lapal tunnel
2014-549: Is passes through a cutting which is part of the cut made in 1838 to accommodate the construction of Lodge Farm Reservoir. Brewins Tunnel was built here, but was uncapped after 20 years. A short arm managed by the Withymoor Island Trust is located on the west bank and is used for moorings. Beyond it, the Bumble Hole Branch partially encircles Bumble Hole, a water-filled former clay pit. This was once
2120-701: Is presumed, introduced in Italy by Bertola da Novate in the 16th century. This allowed wider gates and also removed the height restriction of guillotine locks . To break out of the limitations caused by river valleys, the first summit level canals were developed with the Grand Canal of China in 581–617 AD whilst in Europe the first, also using single locks, was the Stecknitz Canal in Germany in 1398. In

In the 5th century BC, Achaemenid king Xerxes I of Persia ordered the construction of the Xerxes Canal through the base of Mount Athos peninsula, Chalkidiki , northern Greece. It was constructed as part of his preparations for the Second Persian invasion of Greece , a part of the Greco-Persian Wars . It is one of the few monuments left by

They are constructed so the falling water's kinetic energy is dissipated in order to prevent it from scouring the bed and sides of the canal. A canal fall is constructed by cut and fill . It may be combined with a regulator, bridge, or other structure to save costs. There are various types of canal falls, based on their shape. One type is the ogee fall, where

From 1839 to 1843 the Tame Valley Canal was built, along with the Bentley, Rushall and Walsall Junction Canals opening up the Cannock Chase and Wyrley coal districts to the town of Birmingham at a cost upwards of £570,000 (equivalent to £70,680,000 in 2023). The Wyrley and Essington Canal was incorporated by
2650-620: The Birmingham and Dudley Canal Consolidation Act 1846 ( 9 & 10 Vict. c. cclxix), was obtained in the following year and the Dudley Canal ceased to be an independent concern on 27 July 1846. The Birmingham Canal Navigations carried out a number of improvements in the 1850s. Building of Netherton Tunnel was begun on 31 December 1855 and completed on 20 August 1858. It was the last canal tunnel to be built in England and compared to
2756-526: The Dudley Canal Act 1796 ( 37 Geo. 3 . c. 13) was obtained in December 1796 to authorise a further £40,000 and by the time the new route was completed on 28 May 1798, a total of £162.50 had been called on each £100 share. The original shares were worth £118.75 and financial matters were simplified by issuing additional shares so that they all had a nominal value of £100. Lord Dudley resigned from
2862-789: The Birmingham Canal Navigation Act 1792 which authorized the line from Wolverhampton to Sneyd Junction and Walsall. The extension to Huddlesford and the Lord Hay and Daw End branches were constructed under the Birmingham Canal Navigation Act 1794 ( 34 Geo. 3 . c. 87). This amalgamated with the Birmingham Canal Navigations in 1840. In 1855, the Cannock Extension Canal and the Wyrley Bank Branch were added to
2968-706: The Black Country Museum project. Funding for this was provided by the Job Creation Scheme run by the Manpower Services Commission , as a way to provide work and training for the unemployed. The trust were able to use the museum as a base for their electrically powered trip boat, which by then had taken over 25,000 people into the tunnel since the start of trips in 1964. Plans for the No. 2 Line moved forwards in 1980, when

In post-Roman Britain, the first early modern period canal built appears to have been the Exeter Canal , which was surveyed in 1563, and open in 1566. The oldest canal in the European settlements of North America, technically a mill race built for industrial purposes, is Mother Brook between the Boston, Massachusetts neighbourhoods of Dedham and Hyde Park connecting
3286-543: The Naviglio Grande built between 1127 and 1257 to connect Milan with the river Ticino . The Naviglio Grande is the most important of the lombard " navigli " and the oldest functioning canal in Europe. Later, canals were built in the Netherlands and Flanders to drain the polders and assist transportation of goods and people. Canal building was revived in this age because of commercial expansion from

A portion of the ancient canals has been renovated for the Salt River Project and now helps to supply the city's water. The Sinhalese constructed the 87 km (54 mi) Yodha Ela in 459 A.D. as a part of their extensive irrigation network which functioned in a way of a moving reservoir due to its single banking aspect to manage
3498-528: The River Brue at Northover with Glastonbury Abbey , a distance of about 1.75 kilometres (1,900 yd). Its initial purpose is believed to be the transport of building stone for the abbey, but later it was used for delivering produce, including grain, wine and fish, from the abbey's outlying properties. It remained in use until at least the 14th century, but possibly as late as the mid-16th century. More lasting and of more economic impact were canals like

These were used primarily for irrigation and transport. Sunni Ali also attempted to construct a canal from the Niger River to Walata to facilitate conquest of the city but his progress was halted when he went to war with the Mossi Kingdoms . Around 1500–1800

The canal is part of the English and Welsh network of connected navigable inland waterways and forms part of the popular Stourport Ring narrowboat cruising route. The first short section, which connected to the Stourbridge Canal , opened in 1779. This was then connected to the Birmingham Canal system in 1792 via Dudley Tunnel . Almost immediately, work started on an extension, called Line No. 2, which ran through another long tunnel at Lapal to reach
3816-703: The Worcester and Birmingham Canal . This was completed in 1798 but significant trade had to wait until the Worcester and Birmingham was completed in 1802. In 1846, the company amalgamated with the Birmingham Canal Navigations and various improvements followed including the Netherton Tunnel . This was of a similar length to and parallel to the Dudley Tunnel but it was much bigger with towpaths on both sides and gas lighting. It

In Egypt , canals date back at least to the time of Pepi I Meryre (reigned 2332–2283 BC), who ordered a canal built to bypass the cataract on the Nile near Aswan . In ancient China , large canals for river transport were established as far back as the Spring and Autumn period (8th–5th centuries BC),

When this is done with clay, it is known as puddling . Canals need to be level, and while small irregularities in the lie of the land can be dealt with through cuttings and embankments, for larger deviations other approaches have been adopted. The most common
4134-471: The 12th century. River navigations were improved progressively by the use of single, or flash locks . Taking boats through these used large amounts of water leading to conflicts with watermill owners and to correct this, the pound or chamber lock first appeared, in the 10th century in China and in Europe in 1373 in Vreeswijk , Netherlands. Another important development was the mitre gate , which was, it
4240-472: The 15th century, either flash locks consisting of a single gate were used or ramps, sometimes equipped with rollers, were used to change the level. Flash locks were only practical where there was plenty of water available. Locks use a lot of water, so builders have adopted other approaches for situations where little water is available. These include boat lifts , such as the Falkirk Wheel , which use

Thomas Dadford, Sr. was engaged as the engineer and surveyor and acted in this capacity until 1783 after which he was employed more informally. The Dudley Canal Act 1796 allowed the Dudley Canal Company to raise £7,000 and this had been subscribed by July 1778 but

They recommended to the British Waterways Board that much of the Birmingham Canal system should be retained. Canals were grouped into four categories, the first two of which needed little action or expenditure to make them navigable again. The Dudley Canal was in the third category, where it was suggested that

On 26 June 1970, the Inland Waterways Amenity Advisory Council, a government committee created in May 1968, held a press conference at which recommendations about the future of "remainder" waterways were made to the British Waterways Board. "Remainder" was a classification that indicated there

Both the Inland Waterways Association and the IWPS protested, but the protests were ignored, and closure occurred in 1962. Despite this, the Staffordshire and Worcestershire Canal Society explored the tunnel in mid-1963, after which a Dudley Tunnel Committee began running boat trips through it. These proved popular, and

It was found necessary to build an invert through the tunnel because of unstable ground caused by mining below its line and large retaining walls were required at each end. As a result, the cost rose from £238,000 to £302,000 and a tunnel toll was charged to help recoup

There is a well-restored stable block by lock 3, and a grade II listed lock keepers house near the line of the old locks, which was built in 1779, probably to a standard design by Thomas Dadford. Above the locks, the canal passes Merry Hill Shopping Centre , built on the site of Round Oak Steelworks after its closure in 1983. Although it has been closed for more than 100 years,

On more modern canals, "guard locks" or gates were sometimes placed to allow a section of the canal to be quickly closed off, either for maintenance, or to prevent a major loss of water due to a canal breach. A canal fall , or canal drop, is a vertical drop in the canal bed. These are built when the natural ground slope

This would normally be a section of water wider than the general canal. In some cases, the canal basins contain wharfs and cranes to assist with movement of goods. When a section of the canal needs to be sealed off so it can be drained for maintenance stop planks are frequently used. These consist of planks of wood placed across

In 1855 the Lehigh Canal carried over 1.2 million tons of anthracite coal; by the 1930s the company which built and operated it for over a century ceased operation. The few canals still in operation in our modern age are a fraction of

The working capital had risen from just £7,000 to over £200,000 in this period and no dividends had been paid. Traffic through the new tunnel was meagre until 1802 when the Stratford Canal provided a link to the Warwick and Birmingham Canal (later the Grand Union Canal ) and hence to London. The first dividend

Between 1825 and 1837 the navigation was improved between Spon Lane, Deepfield and Wolverhampton, saving a distance of six miles, which reduced the toll on coal by 9d per ton. At the same time the Titford Canal was constructed at a cost upwards of £200,000 (equivalent to £22,960,000 in 2023). The junction with the Warwick and Birmingham Canal was made under powers of an act of 1815 ( 55 Geo. 3 . c. xl). These improvements were all consolidated under

However, this smooth transition does not dissipate the water's kinetic energy, which leads to heavy scouring. As a result, the canal needs to be reinforced with concrete or masonry to protect it from eroding. Another type of canal fall is the vertical fall, which is "simple and economical". These feature

This plan of action had formed part of the Transport Act 1968 , and was adopted soon afterwards for the Dudley Tunnel Branch. The renamed Dudley Canal Trust began to restore the canal. Over the weekend of 26–27 September 1971, they organised "Dudley Dig and Cruise", at which over 600 people cleared a lock chamber and two lock pounds of debris. In early 1972, Dudley Corporation announced that they would provide half of

Another part of the old loop, the Boshboil Arm, turns to the west opposite Windmill End Junction, where to the north lies the southern portal of Netherton Tunnel. Both this portal and the north portal are grade II listed structures. From Windmill End Junction, Line No. 2 continues towards
7738-527: The main shareholders. In 1784, the Stourbridge and Dudley companies approached the Birmingham Canal about a junction. This would involve building extra locks at Park Head and a tunnel which would link to Lord Dudley's existing mining tunnel which joined the Birmingham Canal at Tipton. The Birmingham Canal Company agreed but imposed heavy tolls on traffic using the junction to compensate for the loss of revenue of goods which would formerly have travelled via Aldersely Junction. Lord Dudley agreed to sell his tunnel to
7844-685: The majority of traffic is from tourist and residential narrowboats . The earliest mention of the Birmingham Canal Navigation appears in Aris's Birmingham Gazette on 11 April 1768. Here it was reported that on 25 March 1768, the first general assembly of the Company of Proprietors of the Birmingham Canal Navigation was held at the Swann Inn, Birmingham, to raise funds to submit for an act of Parliament. The first canal to be built in
7950-531: The network at a cost upwards of £100,000 (equivalent to £11,800,000 in 2023). From 1855 to 1858 the Netherton Tunnel and other improvements cost the company upwards of £350,000 (equivalent to £44,490,000 in 2023). In 1776, the Dudley Canal was authorized from Parkhead to the junction with the Stourbridge Canal. The Parkhead to Tipton Green section including Dudley Tunnel was made under
8056-825: The network. There are also stretches on their own levels. The BCN Society is a registered charity (number 1091760) formed in 1968, which exists to conserve, improve and encourage a wide range of interests in the BCN. It publishes a quarterly journal. Boundary Post . From 1983, it erected signposts at most of the canal junctions on the BCN. 52°28′39″N 1°54′32″W / 52.4776°N 1.9088°W / 52.4776; -1.9088 Canal Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation ) or for conveyancing water transport vehicles (e.g. water taxi ). They carry free, calm surface flow under atmospheric pressure , and can be thought of as artificial rivers . In most cases,
8162-506: The numbers that once fueled and enabled economic growth, indeed were practically a prerequisite to further urbanization and industrialization. For the movement of bulk raw materials such as coal and ores are difficult and marginally affordable without water transport. Such raw materials fueled the industrial developments and new metallurgy resulting of the spiral of increasing mechanization during 17th–20th century, leading to new research disciplines, new industries and economies of scale, raising
8268-604: The pre-railroad days of the industrial revolution, water transport was the gold standard of fast transportation. The first artificial canal in Western Europe was the Fossa Carolina built at the end of the 8th century under personal supervision of Charlemagne . In Britain, the Glastonbury Canal is believed to be the first post-Roman canal and was built in the middle of the 10th century to link
8374-452: The short Withymoor branch was built in 1842. In 1813, the Birmingham Canal had suggested amalgamation with the Dudley Canal as a way to prevent continued reductions in tolls but no action was taken. In 1845, with a number of railway schemes threatening the profitability of the canal, a new approach from the Birmingham Canal Navigations was viewed more favourably and a merger was agreed on 8 October 1845. An act of Parliament to authorise it,
8480-445: The south of the Netherton Tunnel at Bumble Hole was eliminated by making a new cut. Dudley Tunnel was closed in 1884 to allow the south end to be rebuilt. The work was completed and the tunnel was reopened on 23 April 1885. It saw considerable traffic with coal and limestone passing southwards and blast furnace slag making the return journey. Subsidence affected the canal in 1894 when a section near Blackbrook Junction, including part of
8586-724: The south-east, but the original line continues through three locks to a junction with the remains of the Pensnett Canal and the Grazebrook Arm, and into the southern portal of Dudley Tunnel. At the far end is the Black Country Museum, which offers boat trips into the tunnel and associated mines. Following Line No. 2 from Park Head Junction, the canal passes around Netherton Hill, where there are mass graves for cholera victims in St. Andrew's churchyard, after which
8692-480: The standard of living for any industrialized society. Most ship canals today primarily service bulk cargo and large ship transportation industries, whereas the once critical smaller inland waterways conceived and engineered as boat and barge canals have largely been supplanted and filled in, abandoned and left to deteriorate, or kept in service and staffed by state employees, where dams and locks are maintained for flood control or pleasure boating. Their replacement
8798-573: The valley of the River Dee . Another option for dealing with hills is to tunnel through them. An example of this approach is the Harecastle Tunnel on the Trent and Mersey Canal . Tunnels are only practical for smaller canals. Some canals attempted to keep changes in level down to a minimum. These canals known as contour canals would take longer, winding routes, along which the land was
8904-428: The wharf at Halesowen opened for business in early 1797. Tunnelling proved difficult. Thirty shafts were dug, to provide multiple work faces, but much of the route was through sand and large quantities of water had to be pumped out of the workings using three steam engines. The £90,000 had been spent by May 1796 and additional calls on the shares were used to raise the extra £40,000 authorised. Another act of Parliament,
9010-469: The whole project for a year after which Robert Whitworth carried out an inspection. He was satisfied and Underhill continued to manage the construction of the tunnel and an aqueduct near the junction with the No.1 Line while management of the rest of the project was handled by Benjamin Timmins. The section from Netherton to Halesowen had been built about 1 foot (0.30 m) too high but this was rectified and
9116-401: Was a member of both the Stourbridge and the Dudley canal company committees. Lees retained his position. In May 1789, there were further issues when it was discovered that the tunnel was not straight. Pratt resigned, and Josiah Clowes was engaged to complete the project. He finished the tunnel, built a new junction with the Birmingham Canal at Tipton and a reservoir at Gad's Green. Completion
9222-410: Was abandoned in the 1960s but a committee was formed, later becoming the Dudley Canal Trust, and restoration took place culminating in the reopening of Dudley Tunnel in 1973. Lapal Tunnel remains closed and although the Lapal Canal Trust originally campaigned for it to be reopened, they have modified their plans to include a surface route following the conclusion of an engineering study. The Dudley Canal
9328-433: Was agreed that those who had been at the meeting would raise £61,500 and that the remaining £28,500 required would be subscribed by existing Dudley shareholders. The line would be constructed at the same level as the Dudley Canal at Park Head. A tunnel of 3,795 yards (3,470 m) would be required at Lapal and a shorter one of 537 yards (491 m) at Gosty Hill. Another short tunnel was to be built at Halesowen but became
9434-466: Was also expensive, as men expect compensation in the form of wages, room and board. This was because long-haul roads were unpaved, more often than not too narrow for carts, much less wagons, and in poor condition, wending their way through forests, marshy or muddy quagmires as often as unimproved but dry footing. In that era, as today, greater cargoes, especially bulk goods and raw materials , could be transported by ship far more economically than by land; in
9540-458: Was an option in some cases, sometimes supplemented by other methods to deal with seasonal variations in flow. Where such sources were unavailable, reservoirs – either separate from the canal or built into its course – and back pumping were used to provide the required water. In other cases, water pumped from mines was used to feed the canal. In certain cases, extensive "feeder canals" were built to bring water from sources located far from
9646-519: Was announced at a shareholder's meeting on 25 June 1792, and the official opening was on 15 October. With the Dudley Tunnel just finished, a meeting was held in Birmingham on 31 August 1792 at which a canal from Birmingham to serve the collieries at Netherton was proposed. The following day, the Dudley Canal Company proposed their own version of a similar canal and following meetings with the Worcester and Birmingham Canal, whose line it would join, it
9752-470: Was gradual, beginning first in the United States in the mid-1850s where canal shipping was first augmented by, then began being replaced by using much faster , less geographically constrained & limited, and generally cheaper to maintain railways . By the early 1880s, canals which had little ability to economically compete with rail transport, were off the map. In the next couple of decades, coal
9858-424: Was increasingly diminished as the heating fuel of choice by oil, and growth of coal shipments leveled off. Later, after World War I when motor-trucks came into their own, the last small U.S. barge canals saw a steady decline in cargo ton-miles alongside many railways, the flexibility and steep slope climbing capability of lorries taking over cargo hauling increasingly as road networks were improved, and which also had
9964-503: Was insufficient to finance the work. The company continued to call money on the shares and raised £9,200 in this way with each £100 share being worth £128. Construction work was completed by 24 June 1779, apart from a water supply reservoir at Pensnett Chase , although little traffic used the canal until the Stourbridge Canal was completed in December of that year. As built, the canal terminated at two basins at Great Ox Leasow and Little Ox Leasow, both built on land owned by T. T. Foley, one of
10070-399: Was no obvious commercial future for the waterway. The recommendations included the returning to "cruiseway" status of nine canals, which included the Dudley Canal. The Waterways Recovery Group, formed in 1970 to co-ordinate volunteer involvement in canal restoration, began work on the canal later that year, raising public awareness of the canal and its potential as an amenity. In December 1970,
10176-600: Was obtained in 1793. The Stratford-upon-Avon Canal was authorised soon afterwards which would provide a connection to London. The original route was renamed "Line no 1" to distinguish it from the new "Line no 2" which linked the canal at Park Head Junction , near Netherton , to the Worcester and Birmingham Canal at Selly Oak , Birmingham via Halesowen and the tunnel at Lapal . Work began in early 1794 with Josiah Clowes as engineer and William Underhill as resident engineer. Clowes died in early 1796 and Underhill managed
10282-400: Was obtained to construct the canal through a detached portion of the county of Shropshire, near Oldbury, and it included powers to make reservoirs anywhere within 3 miles between Smethwick and Oldbury. The Birmingham and Fazeley Canal , from Birmingham to Tamworth, followed in 1784 with the Birmingham Canal Company merging with the Birmingham and Fazeley Canal Company immediately, to form what
10388-426: Was once used to describe linear features seen on the surface of Mars , Martian canals , an optical illusion. A navigation is a series of channels that run roughly parallel to the valley and stream bed of an unimproved river. A navigation always shares the drainage basin of the river. A vessel uses the calm parts of the river itself as well as improvements, traversing the same changes in height. A true canal
10494-579: Was originally called the Birmingham and Birmingham and Fazeley Canal Company . This cumbersome name was short-lived, and the combined company became incorporated as the Birmingham Canal Navigations Company from 1794, as the network was expanded. The Birmingham Canal Navigation Act 1794 ( 34 Geo. 3 . c. 87) authorized the extension from Broadwater to Walsall, and the short cut between Bloomfield and Deepfield, where
10600-465: Was paid in 1804 and although dividends were never high, they averaged around 4 per cent between 1826 and 1844. Dudley Tunnel was popular with tourists and was mentioned in guides to Dudley Castle written by the Rev. Luke Booker in 1825 and W. Harris in 1845. There were complaints that the tunnel was often blocked by unattended limestone boats but this problem seems to have been resolved by 1799 although there
10706-578: Was re-established as a body corporate on 17 June 1835. It was taken over by the London and Birmingham Railway in 1846, and subsequently owned by the London and North Western Railway , then the London, Midland and Scottish Railway until 1 January 1948 when was it passed to the British Transport Commission . The BCN is built on three main levels, each with its own reservoir . These levels are linked by locks at various places on
10812-487: Was seen as part of a scheme to transport coal from coalfields near Dudley to Stourbridge where it would be used for industry. Limestone and ironstone were other potential cargos. A meeting was held in Stourbridge in February 1775 at which Robert Whitworth was commissioned to survey a route and the whole cost of the project was promised. The principal promoter was Lord Dudley and the route ran from Dudley to Stourton on
10918-404: Was suggested, by members of the trust in attendance, that this may have been the first vessel to operate beyond Harborne Lane Wharf, since the brickworks at the Eastern end of the Lapal Tunnel was closed in 1926. Photographs were posted on the Lapal Canal Trust's website. The canal forms an end-on junction with the Stourbridge Canal at the foot of the eight Delph Locks . These are usually known as
11024-408: Was the last canal tunnel built in England. Subsidence from coal mining was a significant problem for much of the life of the canal. The Lapal Tunnel was regularly affected and a section near Blackbrook Junction fell into mine workings in 1894. The route was restored but the short Two Locks Line nearby was abandoned in 1909 and the Lapal Tunnel suffered the same fate in 1917. Most of rest of the canal
11130-502: Was the on-site engineering manager and the main contract for the tunnel went to John Pinkerton. Its width was to be 9.25 feet (2.82 m) with 7 feet (2.1 m) of headroom and 5.5 feet (1.7 m) of water. The contract specified that it should be finished by 25 March 1788. In 1787, Pinkerton's work was thought to be unsatisfactory and work stopped while arguments took place. Dadford was paid off, Pinkerton had to pay half of his £4,000 bond and work restarted with Isaac Pratt in charge. He
11236-399: Was worse and it was closed twice in 1801 and for four months in 1805. Incentives to aid passage through the Lapal Tunnel began in 1820. Any boat carrying over 15 tons could claim one shilling and sixpence (7.5p) for hiring extra leggers. This was increased to three shillings (15p) in 1829 providing the boat was carrying 18 tons. In 1841, the superintendent of the canal, Thomas Brewin, devised
