Lower is better
The Gallows Corner junction and its flyover will be fully closed overnight on Thursday 17 September and then experience a total shutdown from Friday night through to Monday morning. The closures are part of the last resurfacing stage that will restore the carriageways of the A127 and A12.
Schedule of closures
District line service cancelled between Edgware Road and Embankment on 24‑25 Oct 2026
The shutdown also closes Fulham Broadway, Turnham Green and several tram routes, disrupting commuters and football fans across west London.
During the overnight shutdown on 17 September, traffic can still use the roundabout and access to the A12 eastbound, Straight Road and Main Road will remain open. From 10 pm on 18 September all vehicle movements through Gallows Corner will be prohibited, including routes to the A127 Southend Arterial Road, the A12 Colchester Road and the A118 Main Road. Diversion signs will guide drivers onto alternative routes for the three‑day period.
Work scope and contractors
Essex & Suffolk Water has finished its underground work, allowing Costain, the contractor appointed by Transport for London, to start the final reinstatement phase. Costain will lay new surfacing, apply white line markings and commission pedestrian crossings. The work will be carried out in sections to keep disruption to a minimum, but the full weekend closure is required to complete the resurfacing and related safety checks.
