82-531: Grosvenor Bridge , originally known as, and alternatively called Victoria Railway Bridge , is a railway bridge over the River Thames in London , between Vauxhall Bridge and Chelsea Bridge . Originally constructed in 1860, and widened in 1865 and 1907, the bridge was extensively rebuilt and widened again in the 1960s as an array of ten parallel bridges. There are now eight tracks across the bridge. The original bridge

In 1963–1967, the structure of the bridge was completely renewed and modernized, leaving only the cores of the original piers. At the same time, a tenth track was added in a space formerly used for gas mains. To minimize disruption to traffic, each track

The usually quoted source of the Thames is at Thames Head (at grid reference ST980994 ). This is about 1.5 mi (2.4 km) north of the village of Kemble in southern Gloucestershire , near the town of Cirencester , in the Cotswolds . However, Seven Springs near Cheltenham , where

Rennie and William Jessop again proposed four long cuts in 1805, each about 1.5 miles (2.4 km), but the Navigation Committee were thwarted by strong opposition from landowners. Zacchary Allnutt, by then Surveyor for the Second and Third Districts, stretching from Staines to Mapledurham near Reading, suggested locks at Chertsey, Sunbury and Teddington in 1805. Rennie submitted new proposals in 1809 for nine locks between Staines and Twickenham; two would be without weirs, seven would require large weirs to be built. Finally Leach drafted plans in 1810, which he suggested were "at once practicable and expedient,
492-442: A small skiff lock. The barge lock was made to accommodate long barges, steamers or passenger ferries and has an additional set of gates half-way to operate more quickly for shorter craft. The staggered structures incorporate two reinforced narrow islands. The upper island is traversed by and accessible by the lock gates or Teddington Lock Footbridge . The greater lock is against the general south (right, towpath or Surrey) bank of

The river's name has always been pronounced with a simple t /t/ ; the Middle English spelling was typically Temese and the Brittonic form Tamesis . A similar spelling from 1210, "Tamisiam" (the accusative case of "Tamisia"; see Kingston upon Thames § Early history ),
1148-545: Is formed for much of its length for shipping and supplies: through the Port of London for international trade, internally along its length and by its connection to the British canal system. The river's position has put it at the centre of many events in British history, leading to it being described by John Burns as "liquid history". Two broad canals link the river to other rivers: the Kennet and Avon Canal ( Reading to Bath ) and
1230-678: Is found in Magna Carta . The Thames through Oxford is sometimes called the Isis . Historically, and especially in Victorian times, gazetteers and cartographers insisted that the entire river was correctly named the Isis from its source down to Dorchester on Thames and that only from this point, where the river meets the Thame and becomes the "Thame-isis" (supposedly subsequently abbreviated to Thames) should it be so called. Ordnance Survey maps still label

This lock is the lowest full-tide lock and second lowest of all-tide locks on the Thames. The complex of civil engineering or infrastructure in essence consists of a large long weir and three locks: a conventional launch lock in regular use, very large barge lock and
1394-452: Is responsible for managing the flow of water to help prevent and mitigate flooding, and providing for navigation: the volume and speed of water downstream is managed by adjusting the sluices at each of the weirs and, at peak high water, levels are generally dissipated over preferred flood plains adjacent to the river. Occasionally, flooding of inhabited areas is unavoidable and the agency issues flood warnings. Due to stiff penalties applicable on

The lower reaches of the river are called the Tideway , derived from its long tidal reach up to Teddington Lock . Its tidal section includes most of its London stretch and has a rise and fall of 23 ft (7 m). From Oxford to the estuary, the Thames drops by 55 metres (180 ft). Running through some of

In these circumstances, tidal effects can be observed upstream to the next lock beside Molesey weir , which is visible from the towpath and bridge beside Hampton Court Palace . Before Teddington Lock was built in 1810–12,

1968-525: The British Geological Survey from the banks of the tidal River Thames contain geochemical information and fossils which provide a 10,000-year record of sea-level change. Combined, this and other studies suggest that the Thames sea-level has risen more than 30 m during the Holocene at a rate of around 5–6 mm per year from 10,000 to 6,000 years ago. The rise of sea level dramatically reduced when

Thus, the "Churn/Thames" river may be regarded as the longest natural river in the United Kingdom. The stream from Seven Springs is joined at Coberley by a longer tributary which could further increase the length of the Thames, with its source in

The cofferdam protecting the works would need to be removed as river levels rose in the winter, which would have delayed completion until the following July, and so again Leach stepped in, awarding advance payments to the contractors, which enabled them to finish on time. The lock was further upstream than

In the Oxford area the river splits into several streams across the floodplain ( Seacourt Stream , Castle Mill Stream , Bulstake Stream and others), creating several islands ( Fiddler's Island , Osney and others). Desborough Island , Ham Island at Old Windsor and Penton Hook Island were artificially created by lock cuts and navigation channels. Chiswick Eyot
6068-640: The west; the Lister Hospital and the Royal Chelsea Hospital lie immediately to the north west. On the south bank is Nine Elms to the east and Battersea to the west. Battersea Power Station is immediately to the south of the bridge, and Battersea Park to the south west. 51°29′05″N 0°08′51″W / 51.48472°N 0.14750°W / 51.48472; -0.14750 River Thames The River Thames ( / t ɛ m z / TEMZ ), known alternatively in parts as
6150-412: The western part. The area is among the driest in the United Kingdom. Water resources consist of groundwater from aquifers and water taken from the Thames and its tributaries, much of it stored in large bank-side reservoirs . The Thames itself provides two-thirds of London's drinking water, while groundwater supplies about 40 per cent of public water supplies in the overall catchment area. Groundwater
6232-566: The year, while those at Thames Head are seasonal (a winterbourne ). With a length of 215 mi (346 km), the Thames is the longest river entirely in England. (The longest river in the United Kingdom, the Severn , flows partly in Wales .) However, as the River Churn, sourced at Seven Springs, is 14 mi (23 km) longer than the section of the Thames from its traditional source at Thames Head to
6314-406: Was added in 1869 and in the 1870s the weir collapsed twice causing enormous damage. After the weir had been rebuilt in 1871, sluice bays spanned around 240 feet (73 m), similar to the tumbling bays. The footbridges were opened in 1889 and finally the barge lock, the largest lock on the river, was built in 1904–1905. 7,000 cubic yards (5,400 m ) of the extracted gravel was used to raise
6396-479: Was built at the site of London Bridge . London Bridge is now used as the basis for published tide tables giving the times of high tide . High tide reaches Putney about 30 minutes later than London Bridge, and Teddington about an hour later. The tidal stretch of the river is known as "the Tideway ". Tide tables are published by the Port of London Authority and are available online. Times of high and low tides are also posted on Twitter. The principal tributaries of
6478-562: Was constructed in the mid-nineteenth century in two stages: the first bridge was built by the Victoria Station and Pimlico Railway between 1859 and 1860 at a cost of £84,000 to carry two tracks into Victoria Station ; it was the first railway bridge across the Thames in central London. The engineer was Sir John Fowler . The bridge was widened by four tracks on the eastern side for the London, Brighton and South Coast Railway and London, Chatham and Dover Railway between 1865 and 1866, at
6560-458: Was frequently lethal. Some cases continued to occur into the early 20th century. Draining of the marshes helped with its eradication, but the causes are complex and unclear. The East End of London , also known simply as the East End , was the area of London east of the medieval walled City of London and north of the River Thames, although it is not defined by universally accepted formal boundaries;
6642-480: Was renewed separately, and put back into service before the next one was closed. The designer for this work was Freeman Fox & Partners , and the project engineer was A. H. Cantrell, chief civil engineer of the Southern Region of British Rail. It was said to be the busiest railway bridge in the world with 1000 trains crossing per day in 1968. On the north bank is Pimlico to the north and east and Chelsea to
6724-610: Was subject to minor redefining and widening of the main channel around Oxford, Abingdon and Marlow before 1850, when further cuts to ease navigation reduced distances further. Molesey faces Hampton , and in Greater London the Thames passes Hampton Court Palace , Surbiton , Kingston upon Thames , Teddington , Twickenham , Richmond (with a famous view of the Thames from Richmond Hill), Syon House , Kew , Brentford , Chiswick , Barnes , Hammersmith , Fulham , Putney , Wandsworth , Battersea and Chelsea .
