Calls for a new East Thames crossing have been renewed.
It comes after an oil spillage in Blackwall Tunnel resulted in its closure leaving much of South East London gridlocked.
Many residents on both sides of the river are calling for a new road bridge. One such proposal is being currently being considered by the government - Silvertown Tunnel.
However, some politicians and architects say another road crossing is not good for London because it will cause more traffic and more air pollution. Instead they suggest pedestrian and cycle crossings will be better.
