What we did

We replaced the Power Road Bridge as part of our programme to improve London's roads and public spaces.

The bridge, which was built in 1922, had reached the end of its operational life. Not replacing the bridge would mean permanent closures of footway and cycle tracks, lane closures and restrictions on the type or weight of vehicles that use the bridge.


The new structure replacing the existing bridge has been designed to last at least 120 years.

The new bridge has improved footways, lighting and better facilities for cyclists on the western side, making this section of the A406 safer for all users.

Final works

Minor works to the underside of the bridge and railway embankments, which may not be visible from street level, are scheduled for summer 2019.

How your travel might be affected

The nearby A406 Gunnersbury Avenue safety scheme has caused some temporary changes to the road.

  • The A406 Gunnersbury Avenue is currently down to one lane northbound towards Popes Lane until mid-June 2019. Both lanes southbound are open to traffic. Expect delays if driving, especially during morning and evening peak hours
  • A temporary 30mph speed restriction is in place between the Chiswick Roundabout and Park Place Drive
