In civil engineering (more specifically highway engineering ), grade separation is a method of aligning a junction of two or more surface transport axes at different heights (grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads , footpaths , railways , canals , or airport runways . Bridges (or overpasses , also called flyovers), tunnels (or underpasses ), or a combination of both can be built at a junction to achieve the needed grade separation.

33-425: The South East Busway is a grade separated bus-only road running south from the Brisbane central business district to Eight Mile Plains in Queensland , Australia. The busway was completed to Woolloongabba in September 2000 and to Eight Mile Plains in April 2001. An extension of the busway to School Road at Rochedale was completed in 2014 with no additional busway stations. The maximum capacity of

66-452: A grade-separated junction may be referred to as a grade separation or as an interchange – in contrast with an intersection , at-grade , a diamond crossing or a level crossing , which are not grade-separated. Roads with grade separation generally allow traffic to move freely, with fewer interruptions, and at higher overall speeds; this is why speed limits are typically higher for grade-separated roads. In addition, reducing

99-416: A highway) that they cross. However, grade-separated pedestrian crossings with steps introduce accessibility problems. Some crossings have lifts , but these can be time-consuming to use. Grade-separated roads that permit for higher speed limits can actually reduce safety due to 'weaving' (see below) as well as a perceived sense of safety. The term is most widely applied to describe a road junction in which

132-552: A network of five busway corridors were conceived, linking with the rail network to improve public transport connectivity across the city. The busways would improve the operation of the bus fleet, reducing maintenance and running costs and maximising the effectiveness of the region's investment in buses. In August 1996, the Queensland Government approved the South East Transit Project to manage

165-414: A partial grade separation will accomplish more improvement than for a road), and because at-grade railway connections often take up significant space on their own. However, they require significant engineering effort, and are very expensive and time-consuming to construct. Grade-separated pedestrian and cycling routes often require modest space since they do not typically intersect with the facility (such as

231-419: Is fully grade-separated, i.e. traffic on one road does not have to stop at yield lines or signals on one road, but may have to do so when switching to the other: On roadways with grade-separated interchanges, weaving is a result of placing an exit ramp a short distance after an entry ramp, causing conflicts between traffic attempting to leave the roadway at the next junction and traffic attempting to enter from

264-730: Is known as a flying junction and one which is not a level junction . In 1897, the London and South Western Railway (LSWR) made use of a flying junction at Worting Junction south of Basingstoke to allow traffic on the Salisbury and Southampton routes to converge without conflicting movements; this became known as "Battledown Flyover". Also in Britain, the Southern Railway later made extensive use of flying junctions on other parts of its busy former LSWR main line. Today in Britain,

297-626: The Gateway Motorway and terminates at School Road, Rochedale. Whilst the busway alignment plan published in 2010 anticipated a Busway Station at Rochedale, no new busway stations were added by this extension. The proposed location of the Rochedale busway station is further south than the end of the current extension works As part of the upgrade of the Pacific Motorway between Eight Mile Plains and Daisy Hill commenced in 2020,

330-526: The Great Central Railway , built between 1896 and 1899, was the first fully grade-separated railway of this type in the UK. This also applies to light rail and even to street cars . Attempts have been made to increase the capacity of railways by making tracks cross in a grade-separated manner, as opposed to the traditional use of flat crossings to change tracks. A grade-separated rail interchange

396-634: The 1860s, subways are far more common today in Europe, especially in countries such as the Netherlands and Denmark where cycling is strongly encouraged. Long underpasses may be called tunnels . Queen Street bus station Queen Street bus station is the primary bus terminus in Brisbane central business district in Queensland , Australia. It is underneath Uptown, Brisbane (formerly

429-583: The A4/M5 junction west of Bristol . Weaving can often cause side-on collisions on very fast roads with top speeds of up to 200 kilometres per hour, as well as the problem of blind spots. Where junctions have unusual designs weaving can be a problem other than on the main road. An example of this can be found at Junction 7 of the M6, where traffic joining the roundabout from the M6 Eastbound off-slip must weave with

462-584: The Busway will be extended to Springwood , with a new Rochedale busway station to be constructed. The Pacific Highway upgrade and the Busway extension is expected to be completed in 2024. The busway commences at Queen Street bus station beneath the Brisbane central business district , crossing the Brisbane River via Victoria Bridge to the Cultural Centre busway station , then paralleling

495-458: The Eastbound off-slip must leave. Weaving can be alleviated by using collector/distributor roads or braided ramps to separate entering and exiting traffic. In railway construction, grade separation also means the avoidance of level crossings by making any roads or footpaths crossing the line either pass under or over the railway on bridges . This greatly improves safety and is crucial to

528-765: The Myer Centre) & Queen Street Mall . It opened on 26 March 1988 along with the Myer Centre. At the time it was the largest underground diesel bus station in the world. Queen Street bus station serves as the terminus of many routes servicing the South East Busway , Southern and Eastern Suburbs and the Centenary / Indooroopilly / Kenmore corridor. It is served by 35 routes all operated by Transport for Brisbane . No Northern Busway services directly connect King George Square busway station with

561-566: The Queen Street busway station. After stopping at King George Square, a number of inbound services bypass the Queen Street stop or terminate at the Cultural Centre on the southern side of the Brisbane River , and vice versa. However, King George Square and Queen Street are only a short walking distance apart. The station is divided into several platforms originally named after Australian native animals, but are now identified with letters and numbers: Passengers wait behind automatic doors on

594-538: The South East Busway from Eight Mile Plains Busway Station to Rochedale Busway Station was proposed in July 2006 as part of the Queensland Government's Pacific Motorway Transit Project. As part of the project, plans were made to extend the South East Busway as far as Springwood bus station , including construction of the proposed Rochedale busway station . The preferred alignment for the busway extension corridor

627-611: The busway is 18,000 commuters an hour during peak periods. The busway carries an estimated 70 million passengers annually. The busway allows services to branch off along any part to service nearby suburbs. This has been described as the Quickway model of bus rapid transit. Busways were considered as one of the options when the Queensland Government developed the 25 year Integrated Regional Transport Plan. Other methods such as light and heavy rail were also considered. It

660-515: The capacity of a road compared to an identical road with at-grade junctions. For instance, it is extremely uncommon to find an at-grade junction on a British motorway ; it is all but impossible on a U.S. Interstate Highway , though a few do exist. If traffic can traverse the junction from any direction without being forced to come to a halt, then the junction is described as fully grade separated or free-flowing . These junctions connect two freeways: These junctions connect two roads, but only one

693-725: The complexity of traffic movements reduces the risk of accidents . Grade-separated road junctions are typically space-intensive, complicated, and costly, due to the need for large physical structures such as tunnels, ramps, and bridges. Their height can be obtrusive, and this, combined with the large traffic volumes that grade-separated roads attract, tend to make them unpopular to nearby landowners and residents. For these reasons, proposals for new grade-separated roads can receive significant public opposition. Rail-over-rail grade separations take up less space than road grade separations: because shoulders are not needed, there are generally fewer branches and side road connections to accommodate (because

726-827: The construction of both the northern section of the Pacific Motorway between Mount Gravatt and Logan City and a dedicated 2-lane, 2-way road for buses between the Brisbane CBD and Eight Mile Plains . The first section of busway between the existing Queen Street bus station and Woolloongabba was opened to services on 13 September 2000 to coincide with the start of the 2000 Olympic football tournament , for which some matches were held in Brisbane. It initially opened for outbound services only, with inbound services commencing on 23 October 2000. The second 13.2 km (8.2 mi) section of busway between Woolloongabba and Eight Mile Plains opened on 30 April 2001. The extension of

759-571: The direct flow of traffic on one or more of the roads is not disrupted. Instead of a direct connection, traffic must use on and off ramps ( United States , Australia , New Zealand ) or slip roads ( United Kingdom , Ireland ) to access the other roads at the junction. The road which carries on through the junction can also be referred to as grade separated . Typically, large freeways , highways , motorways , or dual carriageways are chosen to be grade separated, through their entire length or for part of it. Grade separation drastically increases

792-636: The faster speed requires grade separation. Therefore, many high speed lines are elevated, especially in Taiwan and Japan , where population density alongside high speed lines is higher than in France, Italy or Germany. In the United States, a flying junction on the Nickel Plate Road through Cleveland , Ohio , United States was completed in 1913. The most frequent use was later found on

825-508: The former Pennsylvania Railroad main lines. The lines are included as part of the Northeast Corridor and Keystone Corridor now owned by Amtrak . The most complex of these junctions, near Philadelphia Zoo , handles railway traffic for Amtrak, SEPTA , New Jersey Transit , Norfolk Southern , CSX Transportation , and Conrail . In what is known as "area 1520" , which includes the former Soviet Union and other regions using

858-544: The previous junction. This situation is most prevalent either where the junction designer has placed the on-slip to the road before the off-slip at a junction (for example, the cloverleaf interchange ), or in urban areas with many close-spaced junctions. The ring road of Coventry , England , is a notorious example, as are parts of the southern M25, the London orbital motorway , the M6/M5 junction north-west of Birmingham , and

891-557: The safe operation of high-speed lines. The construction of new level crossings is generally not permitted, especially for high speed railway lines and level crossings are increasingly less common due to the increase of both road and rail traffic. Efforts to remove level crossings are done in the UK by Network Rail and in Melbourne as part of the Level Crossing Removal Project . The London Extension of

924-747: The same gauge, the most complicated grade-separation railpoint is found at Liubotyn in Ukraine . Footbridges and subways (called underpasses in North America as well as in the United Kingdom when referring to roads) may be employed to allow pedestrians and cyclists to cross busy or fast streets. They are often used over and under motorways since at grade pedestrian crossings are generally not permitted. Same can be said for railways. Though introduced to Central Park in New York City in

957-405: The stop that is assigned to their bus. In June 2015, the platforms were again renamed, becoming numbers. The station has a portal for buses traffic to enter and leave at the northern end of Victoria Bridge , to connect to the Cultural Centre busway station . The former entry/exit portal (on Albert Street , facing King George Square ), from the Queen Street busway station, was converted into

990-400: The tightly grouped nest of flying junctions to the north of Clapham Junction railway station —although technically a combination of many junctions—handle more than 4,000 trains per day (about one train every 15 seconds). Virtually all major railway lines no longer cross (forming an 'X' shape ) at flat level (although many diverge - i.e. 'Y' shape). On almost all high-speed railway lines,

1023-548: The traffic already on the roundabout wishing to use the M6 Westbound on-slip. This is as a result of the slip roads on the west side of the junction connecting to the roundabout on the inside of the eastern arc rather than the outside of the western arc as is normal. The two slip-roads are connected by a single lane on the inside of the roundabout, which traffic wishing to use the Westbound on-slip must join, and traffic from

1056-654: Was determined in 2007 and a Concept Design Study was undertaken by the Queensland Government in 2009. Construction of the Eight Mile Plains to Rochedale extension to the Busway commenced in late 2012 and was completed in March 2014. The extension had an estimated cost of $ 36 million. The extension was funded by the Queensland Government ($ 36m) and formed part of the Federal Government's Gateway Upgrade South (GUS) project. The busway extension passes under

1089-414: Was recommended that a 75 km (47 mi) network of busway corridors to complement the existing Queensland Rail City network would suit best. Busways would allow buses to serve low-density communities and bypass peak hour congestion. Busway stations could be developed at key nodes to serve major activity centres, and combining different routes would create high frequency services. In 1995, plans for
