The Thames Gateway Bridge was a proposed crossing over the River Thames in east London, England. It was first mooted in the 1970s but never came to fruition. In November 2008, Boris Johnson, the then Mayor of London, formally cancelled the entire £500 million scheme.
In 2009, a new scaled-down project was launched involving a potentially new crossing between Tower Bridge and the Dartford Crossing.
It was planned that the bridge should be built by 2013 and would have connected Beckton in the London Borough of Newham with Thamesmead in the Royal Borough of Greenwich linking the A406/A13 junction in Beckton with the A2016 Eastern Way and Western Way in Thamesmead and serve the new Thames Gateway development.
The bridge was to have a span of about 650 metres (0.4 mi), with a 50-metre (160 ft) vertical clearance for ships but be low enough not to impede the flight approach to the nearby London City Airport. The bridge was to have had four lanes for general traffic and two lanes for public transport use. It would also have had a cycle lane, a pedestrian walkway and the facility for a Docklands Light Railway crossing.
For pedestrians the nearest other crossings are the Greenwich foot tunnel, the Woolwich foot tunnel and Woolwich Ferry, or the Docklands Light Railway, from King George V station under the river to Woolwich Arsenal station, which opened in early 2009.
