The maintenance work was needed to ensure the flyover remains structurally sound and continues to serve the area for the next 20 to 30 years. Hogarth flyover, which is nearly 50 years old, is used by around 10,500 vehicles a day to go eastbound from the A316 to the A4 Great West Road.
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 to the structure, waterproofed and a new road surface, kerbing and parapets installed.
New LED lighting on the slip road from the flyover has also been fitted, helping to improve visibility for vehicles entering the A4.
Now the highway elements of the works are complete, we will begin to upgrade the pedestrian subways near the Hogarth Roundabout, as well as replant trees and flowers around the roundabout to improve the look of the area.
