The Highways Agency will be undertaking essential carriageway maintenance work, to address surface defects on the roundabout circulatory and westbound exit slip-road for the M4 at Junction 15 ( Swindon ). Work will also include repairs to the joints on each of the bridges, which cross the M4 motorway.
The work is scheduled to start on Monday 30 January 2012 for seven consecutive nights, weather permitting, and will be undertaken between 22:00 and 06:00 hours (Monday to Thursday, and Saturday nights), between 23:00 and 06:00 hours (Friday night) and between 20:00 and 06:00 hours (Sunday night).
To reduce disruption to road users and for the safety of our work force, work will be carried out with closures to sections of the roundabout circulatory and the slip-roads, during the hours detailed above. These will be split into south-side or north-side closures, and will involve:
- Northern-side: Full closure of the eastbound exit and entry slip-roads, the carriageway over each bridge (where it crosses the M4 motorway) and around the north-side of the roundabout
- Southern-side: Full closure of the westbound exit and entry slip-roads, the carriageway over each bridge (where it crosses the M4 motorway) and around the south-side of the roundabout
Weather permitting, the closures are currently programmed to take place on the following dates and are subject to change:
- Monday 30 & Tuesday 31 January - Northern-side closures
- Wednesday 1 & Thursday 2 February - Southern-side closures
- Friday 3 & Saturday 4 February - Lane closure on the westbound exit slip-road and around the roundabout circulatory
- Sunday 5 February - Southern-side closures

During all closures, clearly signed diversion routes will be in place.
