Hammersmith flyover

Hammersmith flyoverHammersmith flyover

This final phase of strengthening the Hammersmith flyover follows on from repairs made in early 2012. Completed in 1961, the Hammersmith flyover carries the four-lane A4 arterial road over the Hammersmith gyratory and links the west to central London.

Strengthening the flyover will prolong its life and mean no major maintenance will be required for many years, ensuring this vital part of the road network can continue serving London for years to come. Work to upgrade the central reservation is now complete, with strengthening to the structure now fully underway.

Hammersmith flyover - weekend improvement work finishes early

Following excellent progress with recent improvement work, we no longer require the two remaining scheduled weekend closures of the westbound Hammersmith flyover. This means that it will be open as normal this weekend.

We will continue to carry out work on the structure at other times, primarily overnight so that traffic restrictions are minimised to reduce disruption to road users and local residents.

      Why are we doing the work?

      In December 2011, structural investigations revealed that steel cables on a number of the flyover's 16 spans had deteriorated significantly, due to corrosion caused by water seeping into the structure.

      We carried out urgent strengthening work on the worst-affected spans, and now need to strengthen the remaining spans and undertake essential planned maintenance.

      The first of the new strengthening cables will start being installed from August 2014 and, later this year, steel bearings within the structure will also be replaced.
