The M4 motorway has reopened in both directions a week after it was closed for emergency repair works.
The road was shut last Friday between junctions 2 and 3 after cracks were discovered on a bridge.
Engineers have completed the repair work and it was opened to the traffic around 5.30am.
A Highways Agency spokesman said: "An exceptionally delicate and difficult operation to repair cracks in the Boston Manor Viaduct on the M4 has been successful and the motorway has now reopened between junctions 2 and 3 to all cars."
The M4 is expected to be one of the busiest routes during the Olympic Games, and hundreds of athletes are due to start arriving at Heathrow from Monday.
