A4 carriageway surface

The existing carriageway surface on the Keynsham Bypass, from Broadmead roundabout through towards Hicks Gate roundabout, has reached the end of its life and as a result requires frequent maintenance intervention. 

Bath & North East Somerset  were successful with a Challenge Fund bid in partnership with Bristol City Council to the Department for Transport which will enable us to fully resurface the whole bypass and both roundabouts in two phases starting this September.  As this is a busy section of road, with a high volume of commuter traffic, works will be carried out overnight where possible in order to minimise delays and maintain public transport routes. During resurfacing, a day time lane closure with a speed restriction will be in place on the westbound carriageway to maintain safety on the temporary road surface.

Phase one of the works will see two kilometres of westbound carriageway and Broadmead roundabout resurfaced overnight, starting this September for up to three weeks.  This phase of work will also include vehicle restraint system (VRS) replacement & upgrade works, new traffic counter loops & replacement road markings.  During night time works, the bypass is planned to remain open and manually operated temporary traffic signals will be installed on the approaches to Broadmead roundabout to control traffic.  There will also be two nights which will require the approach to Broadmead roundabout to be closed from Keynsham.  A signed diversion route through Keynsham will be in place on this occasion.

Phase two, planned for April/May 2018 will include bridge deck waterproofing and eastbound carriageway resurfacing including Hicks Gate roundabout and its approaches from Bristol, Keynsham and the A4174 Ring Road (South Gloucestershire Council). Further details on the delivery of this phase of works will be published in the new year.

The project will substantially improve the road surface, reducing disruption from unplanned future maintenance and less road noise for adjacent residents.

The works are starting on 25 September and are expected to take up to three weeks to complete. Working hours will be 8pm to 6am. Any changes to delivery dates as a result of inclement weather or other delays will be updated on this page as the project progresses and alerts issued on the Council’s twitter feed.
