Motorists are being warned of severe delays after part of a road tunnel was shut after a bus was destroyed by fire.
The fire on Sunday destroyed the bus
Transport for London (TfL) said the Limehouse Link Tunnel was likely to remain closed for at least a week and advised motorists to avoid the area.
Engineers are still assessing the extent of the damage to the eastbound section.
The driver escaped unhurt when the empty double-decker broke down and burst into flames on Sunday morning.
The westbound carriageway reopened a few hours after the fire but drivers have been warned to expect severe delays in the surrounding area.
Traffic is being diverted from Tower Bridge and Lower Thames Street via Mansell Street and the Aldgate one-way system.
TfL's Peter Hendy said: "There is a lots of smoke and smoke damage from the fire... they need to look at the structure of the tunnel to check if it's damaged".
The Limehouse Link Tunnel connects central London with the Docklands.
