Chiswick Flyover repairs underway

National Highways has begun several months of safety-critical work to the M4 Chiswick Flyover in West London.

Contractors Connect Plus will be carrying out concrete repairs to the reinforced bridge piers which support the elevated section of the M4 (A4 Great West Road/M4 Chiswick Flyover) until May.

So that work can be undertaken safely, lane closures will be in place on the A4 Great West Road, between Boston Manor Road and Lionel Road South, throughout the duration of our work. Structural repairs will take place during the week, mainly between 7:30am and 5:30pm. National Highways says this work will keep the structure safe and extend its serviceable lifespan.

Contractors will also erect scaffolding and debris netting around the piers and equipment will be on site to help monitor noise and dust levels.

A 30mph speed restriction will be in place for safety and some pedestrian crossing points may need to be suspended for public safety. Signed diversions will be in place to the next available pedestrian crossing where applicable.

The work will need some full overnight road closures at the beginning and end of the project to safely install and remove the required traffic management.
