Roadworks are set to begin this week in Greenwich at Blackwall Lane which could see disruption in the area.
Bus routes 108, 188 and 422 will be diverted with TfL warning about the potential of longer gaps between buses. Bus diversions will begin on Saturday 28th.
TfL state its gas works while other sources state Thames Water are behind the closure.
The Blackwall Lane southbound will be closed from the Peninsula including the section below the A102 flyover approaching the Blackwall Tunnel.
Works are expected to take around two weeks to complete.
