South West – Weekly round up of road works in Wiltshire, Gloucestershire, Somerset, Bristol & Devon – 12/09/2008
M5 Avonmouth Bridge
Major resurfacing and waterproofing work started on the southbound carriageway of the M5 Avonmouth Bridge overnight on 2 September and will continue until January.
During the work there will be narrow lanes and a 50 mph speed limit controlled by speed cameras. At times there will be a contraflow. Three lanes will remain open in each direction throughout the work.
M4 J18 to J19 Eastbound
Geotechnical repairs and installation of new drainage to motorway embankment are being carried out over a period of four weeks to end of September. The hard shoulder will be closed with three narrow lanes and 50mph speed restriction.
A40 Over to Highnam (near Gloucester)
A 26-week scheme to reconstruct both carriageways and to build a new bus lane started in May. The scheme also includes renewing drainage, replacing lighting columns, new cabling and safety barriers.
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 until mid October, 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 late September for the erection of overhead gantries.
A419 Blunsdon near Swindon
There are narrow lanes and speed restrictions on the A419 near Swindon as part of the construction of the Blunsdon Bypass. Northbound traffic is now using the new bypass while southbound traffic continues to use the existing A419 through Blunsdon.
