Essential road improvement works to Hogarth Flyover in London will take place this summer.
The flyover is nearly 50 years old and now requires essential maintenance work to ensure it continues to serve the area for the next 20 to 30 years.
If the works are not done soon, then the structure may become unsafe, which would require Transport for London (TfL) to close the flyover at very short notice.
From 19 July until 31 August, the single lane eastbound only flyover, which carries traffic from the A316 onto the A4 Great West Road, will be closed to traffic to allow engineers to replace the deck, repair parapets steelwork, and improve lighting on the slip road. The essential refurbishment works have been phased and coordinated to take place during the summer when traffic levels are significantly lower, helping to reduce the impact on road users.
Garrett Emmerson, chief operating officer for surface transport at TfL, said: "London is living with the legacy of life expired 1960s roads infrastructure; now we need to prepare for the next 30 years. These important works to the Hogarth Flyover will ensure that this vital structure can remain open for years to come, reducing the need for further works in the future while ensuring traffic can continue to flow into and around London.
"Whilst there is obviously no perfect time to close such an essential piece of road infrastructure for major maintenance, doing it during the school summer holidays when traffic levels are up to 15% lower, and working 24 hours, seven days a week to complete the works in just six weeks, will minimise disruption for Londoners on this important road corridor."
Additionally in the area, Wandsworth Council are carrying out essential works to refurbish Putney Bridge from 14 July.
