Find out about the Mannington roundabout project

Latest news and updates

Mannington roundabout is a key intersection in Swindon’s strategic road network, connecting the M4 Junction 16 to the town centre and beyond. Due to the increase in traffic on Swindon’s roads this junction has, over the years, become heavily congested at peak times.

Funding has been secured from the Swindon and Wiltshire Local Enterprise Partnership to develop a scheme aimed at alleviating the congestion and improving conditions for those using the roundabout. This project is part of a package of measures totalling £3.2 million which will deliver a Quality Bus Corridor from Wichelstowe to the town centre, providing more reliable journey times.

Phase 1-3 - complete

Work on the scheme began in February 2018 with the successful removal of the Wootton Bassett Road bus lane between Mannington Roundabout and the railway bridge. 

The work on Tewkesbury Way was completed in July 2018 and involved the removal of the physical traffic island and shortening of the bus lane in order to extend the 3 lane approach Mannington Roundabout, providing more queuing space.

Phase 3 was completed in February 2019, and contributes to the improved traffic flow from Great Western Way B4006 into Wootton Bassett Road (by the Fish Brothers garage).  The main construction for this phase of the project began on Wootton Bassett Road where the road was widened on the Northern and Easterly arms of the roundabout.

Phase 4 – starting June 2019

The final phase of the project will be based at Mannington Retail Park. Construction of a new merging on-slip lane from the retail park onto Great Western Way (A3102) will reduce the volume of traffic leaving the retail park at Wootton Bassett Road and entering Mannington Roundabout. Within the retail park itself, Telford Way will be widened to allow for two-way flow and new traffic signs will be installed, improving the internal flow to make it much simpler and efficient.

The speed limit will be reduced to 40mph for traffic heading westbound from Mannington towards Blagrove, to a point just past the Retail Park. We will also provide a new system of street lighting in this area. The speed limit will also be reduced to 50mph for eastbound traffic approaching Mannington from Blagrove. These changes seek to improve overall safety and reduce the number of road traffic accidents in this area.

During construction, traffic visiting the retail park will be diverted via the main car park whilst works take place to widen a section of Telford Way. There will also be two narrow lanes running on Great Western Way during the tie in of the new exit lane from the retail park. Exact dates will be confirmed nearer to the time and advanced notice boards will be erected on site two weeks prior to commencement.
