On 4 July 2010 Transport for London announced plans to develop a cable car crossing over the River Thames. It is the first urban cable car in the United Kingdom. Designed by Wilkinson Eyre Architects, Expedition Engineering and Buro Happold, it crosses the river at a height up to 90 metres, higher than that of the nearby O2 Arena. The cable car provides a crossing every 15 seconds, with a maximum capacity of 2,500 passengers per hour in each direction, about 50 busloads. Bicycles may be carried. Passengers can pay for their journeys with pay-as-you-go Oyster cards.
