The A102 has reopened as firefighters continue to battle a fire in a motorcycle repair shop near the Blackwall Tunnel.
The closure caused delays along Commercial Road and the A13.
Six fire engines and 35 firefighters from Poplar and elsewhere are tackling the blaze at the shop in Peterboat Close in Greenwich.
The London Fire Brigade has set up a 200m hazard zone over the risk of gas cylinders at the shop exploding, and advise people to avoid the tunnel and nearby roads.
The fire was reported to the LFB at 6am this morning, and has caused heavy traffic near the tunnel and shut the A102 going northbound at Shooters Hill Road.
