Four reinforced concrete trusses were inserted under the roadway around 1929, giving it the strength which today allows it to carry 38 tonne trucks. Bath has no eastern bypass, so
5680-408: The schooner Gipsy in 1878, the steam tug Black Eagle in 1861 and the Llandaff City . In 1877, Halfpenny Bridge, a pedestrian toll bridge crossing the river from Bath Spa railway station to Widcombe , collapsed with the loss of about 10 lives amongst a large crowd going to the Bath and West Agricultural show . The Avon has flooded several times in its recorded history. These floods include
5760-407: The south side of the river. It was designed by architect Henry Goodridge to take the traffic of his day, horse-drawn vehicles and pedestrians, and was constructed using Bath Stone and a cast iron arched span. Pulteney Bridge was completed in 1773 and is designated by English Heritage as a Grade I listed structure. The bridge was designed by Robert Adam , and is one of only four bridges in
5840-592: The southern edge of the Cotswold hills , at Didmarton in Gloucestershire; at Joyce's Pool a plaque marks the source. It flows south-east into Wiltshire to Sherston , where it is joined by the Luckington Brook which drains an area west of Luckington that includes the Badminton House estate. From Sherston the river flows east to Malmesbury , where it is joined by its first major tributary,
5920-494: The traffic of his day, horse-drawn vehicles and pedestrians, and was constructed using the warm golden Bath Stone and an elegant cast-iron arched span. A toll house was required to charge users of the bridge for the privilege of crossing. Rather than building merely one, Goodridge decided to install four — one on each corner — in order to maintain the absolute symmetry of his elegant neoclassical design. He provided each of these lodges with columns fronting onto
6000-504: The urban area one water body is rated good, while 12 are rated moderate and one is poor. The pollution from upstream is added to by the effects of industry, manufacturing and other businesses and is significantly affected by physical modifications to the water course. Within the catchment area there are 137 river water bodies and 6 lakes; of these 22 per cent of rivers are rated as good ecological status, 40 per cent good for chemical status and 31 per cent good for biological status. The river
6080-429: The wheel uses 2 tons (2 tonnes ) of water per second and rotates five times a minute. The water wheel drives gearing which increases the speed to 16 rpm . From here, cranks drive vertical connecting rods which transfer the energy to two 18 ft (5.5 m) long cast iron rocking beams. Each rocking beam in turn drives an 18 in (0.5 m) diameter lift pump , which also take their supply from
6160-401: The wider area, they have aided the development of a scientific understanding of the history of early glaciation within South West England . At Horseshoe Bend, Shirehampton the wooded cliff and a narrow salt marsh are supported by rocks of Devonian age Old Red Sandstone and Carboniferous Limestone , overlain by with Triassic dolomitic conglomerate . The site's principal interest and
6240-643: The world with shops across the full span on both sides. It is named after Frances Pulteney , heiress in 1767 of the Bathwick estate across the river from Bath. Floods in 1799 and 1800 wrecked the north side of the bridge, which had been constructed with inadequate support. It was rebuilt by John Pinch the Elder , surveyor to the Pulteney estate, in a less ambitious version of Adam's design. Bath and North East Somerset council have discussed plans to ban vehicles from
6320-437: Was built and has been repaired many times. The Dundas Aqueduct was built by the same team between 1797 and 1801 and completed in 1805. James McIlquham was appointed contractor. The aqueduct is 150 yards (137.2 m) long with three arches built of Bath Stone , with Doric pilasters, and balustrades at each end. The central semicircular arch spans 64 feet (19.5 m); the two oval side arches span 20 feet (6.1 m). It
6400-490: Was transferred to the Secretary of State for Scotland. The growth of road transport increased the responsibilities of the ministry, and in the 1930s, and especially with defence preparations preceding the outbreak of war, government responsibilities for all means of transport increased significantly. Government control of transport and diverse associated matters has been reorganised a number of times in modern history, being
