The Colne Valley Viaduct (CVV) will cross Moorhall Road at a point between Korda Lake and Savay Lake, just south of the Grand Union Canal. The building of the support structures for the crossing, and the crossing of the road itself, require a series of traffic management phases starting with a single lane closure, followed by overnight road closures and then a full road closure during the day and night to allow this to be done safely.
Phased road traffic management on Moorhall Road from Saturday 15 July to Friday 27 October 2023, ranging from a single lane closure to a full road closure for all vehicles from Friday 28 July to Friday 18 August 2023.
The route 331 bus from Uxbridge to Ruislip (via Denham) will be rerouted during the periods of full road closure of Moorhall Road. Transport for London operate this bus service and full information of service changes will be provided at https:tfl.gov.uk/bus/status/ in advance of the road closures.
