Question: What bridge is the London Assembly close to in River Thames?
Context: London Bridge City Pier (also known as London Bridge Pier and City Pier) is situated on the south bank of the River Thames in London, UK, close to London Bridge.  It serves as the main pier for the City of London and City Hall, headquarters of the London Assembly. The London Assembly is an elected body, part of the Greater London Authority, that scrutinises the activities of the Mayor of London and has the power, with a two-thirds majority, to amend the Mayor's annual budget and to reject the Mayor's draft statutory strategies.  The assembly was established in 2000 and meets at City Hall on the south bank of the River Thames, close to Tower Bridge.  The assembly is also able to investigate other issues of importance to Londoners (transport, environmental matters, etc.), publish its findings and recommendations, and make proposals to the Mayor. The Thames Conservancy (formally the Conservators of the River Thames) was a historical body responsible for the management of the River Thames in England.  It was founded in 1857, initially replacing the jurisdiction of the City of London up to Staines and later taking responsibility for the whole river from Cricklade in Wiltshire to the sea at Yantlet Creek on the Isle of Grain.  Responsibilities were reduced when the Tideway was transferred to the Port of London Authority in 1909 and in 1974 the Conservancy was taken into the Thames Water Authority. Culham Bridge is a mediaeval bridge crossing a present backwater of the River Thames in England at Culham, Oxfordshire, near the town of Abingdon.  The bridge crosses Swift Ditch which was at one time the main navigation channel of the River Thames until Abingdon Lock was built in 1790.  The bridge formerly carried the A415 road from Abingdon to Dorchester, Oxfordshire, but was superseded in 1928 by a modern road bridge. City Hall is the headquarters of the Greater London Authority (GLA), which comprises the Mayor of London and the London Assembly.  It is located in Southwark, on the south bank of the River Thames near Tower Bridge.  It was designed by Norman Foster and opened in July 2002, two years after the Greater London Authority was created. Noel Lynch (born 20 January 1947) is a politician living in England and a prominent member of the Green Party of England and Wales.  He represented the Green Party on the London Assembly between 2 May 2003 and 10 June 2004, after replacing Victor Anderson who resigned.  Due to a fall in the Green vote, he did not retain his seat at the 2004 London Assembly election, leaving Cllr.  Darren Johnson AM and Cllr.  Jenny Jones AM as the remaining members of the London Assembly Green Group.  He is currently Co-ordinator of the London Federation of Green Parties. North East is a constituency of the London Assembly.  It is represented by Jennette Arnold who was directly elected at the 2004 London Assembly election after previously being elected by the Labour Party list in the 2000 London Assembly election. Tower Bridge is a combined bascule and suspension bridge in London built between 1886 and 1894.  The bridge crosses the River Thames close to the Tower of London and has become an iconic symbol of London, resulting in it sometimes being confused with London Bridge, situated some 0.5 mi upstream.  Tower Bridge is one of five London bridges now owned and maintained by the Bridge House Estates, a charitable trust overseen by the City of London Corporation.  It is the only one of the Trust's bridges not to connect the City of London directly to the Southwark bank, as its northern landfall is in Tower Hamlets. The Garden Bridge project was a private proposal for a pedestrian bridge over the River Thames in London, England.  Consequent on an idea of Joanna Lumley, Thomas Heatherwick worked with Arup on a proposal by Transport for London (TfL) for a new bridge across the Thames between Waterloo and Blackfriars bridges.  The proposed concrete, steel, cupronickel clad structure was intended to carry pedestrians, with no cycles or other vehicles.  It was to have been located some 200 m from Waterloo Bridge and 300 m from Blackfriars Bridge, and have included some areas of planting.  The project included a commercial building, built on former green space at the southern end of the bridge.  The bridge could only be funded by raising over £140 million of private money (including charitable gift aid) and £60 million of promised public money, of which £30m was from Transport for London (£20m of this to be repaid over 55 years) and £30m from the Department for Transport, adding up to projected funding of over £200m in total, In January 2017 the trustees of the prospective owner of the bridge stated that costs would "substantially exceed" an earlier revised total of £185m and in April 2017 the report by Margaret Hodge (below) concluded, on the basis of the Garden Bridge Trust's own evidence to her, that the cost would be over £200m. The London Assembly election of 2012 was an election of members to the London Assembly which took place on Thursday, 3 May 2012, the same day as the London mayoral election, 2012, and the United Kingdom local elections, 2012.  Although Conservative candidate Boris Johnson won the Mayoral election, the Assembly election produced the Labour Party's best result since the inception of the London Assembly; this was subsequently surpassed by the party's performance in the 2016 election.
