Improvements so far

Maintenance work was needed to ensure the flyover remains structurally sound.

Temporary closures of the flyover allowed engineers to replace the deck, repair the supporting steelwork and install upgraded parapets. The old deck was demolished and 86 new concrete panels craned onto the structure. The new deck was then secured, waterproofed and a new road surface, kerbing and parapets were installed. LED lighting on the slip road from the flyover was also fitted, helping to improve visibility for vehicles entering the A4.
