Major Road Closure – A4 London

Transport for London have said that the Hammersmith flyover (A4) will remain closed in both directions for urgent structural repairs. The damage has been caused by water leaking into the structure, including salt water due to de‑icing salt laid during the winter months, which has corroded and weakened the cables that help support the flyover.

Safety is our top priority and we are working flat out, including inside the structure, to assess the damage and put in place a solution that will enable us to open the flyover as soon as possible and to identify the best long‑term solution.

Local traffic diversions are currently in place, along with Variable Messaging Signs and traffic signal plans are being developed to reduce disruption and ease traffic flow however if you drive in London, you are strongly advised to avoid the area and seek alternative routes.

We are working hard to complete the essential repairs. For live traffic news and advice please visit tfl.gov.uk/roadusers
