There will be an overnight closure of the B4215 at it’s junction with the A40 on Monday night (8 Sept – 8pm to 6am) to carry out repairs to the kerb and footway on the corner of the junction.
A contraflow has been installed with one lane in each direction until completion of the work in November. Temporary traffic signals have been installed on Over roundabout to improve traffic flow onto the A417.
A4 Avonmouth – work on St Brendans and St Andrews roundabouts
Due to the continued development of Cabot Park Distribution Park, improvements to St Brendans and St Andrews roundabouts are being carried out.
The improvements include widening of the carriageway approaches to the two roundabouts to enable increased turning space for large goods vehicles, and the signalisation of the roundabouts to facilitate improved traffic flow.
Work will continue the end of September, during which time there will be 24-hour lane closures in place at various locations and a temporary limit of 30mph. A number of full overnight closures of the roundabouts will be required during mid-September for the erection of overhead gantries.
