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 - complete
Work on the scheme has already begun with the successful removal of the Wootton Bassett Road bus lane between Mannington roundabout and the railway bridge. This was done overnight in order to minimise disruption to traffic and the new layout on Wootton Bassett Road is working well. Some vegetation has also been cleared by the Mannington Retail Park which had to be completed before bird nesting season began in March.
Phase 2 – started April 2018
The work on Tewkesbury Way is nearly finished. After the discovery of an unknown cable when we started to remove the traffic island on Tewkesbury Way, we are pleased to say that work is now progressing quickly. Although we couldn’t identify who owned the cable, we’ve now been able to work around it, though this has extended the programme slightly.
Although we have maintained two-way traffic throughout the project so far, we will have to completely close Tewkesbury Way to resurface the road. This will be done overnight between Monday, 16 July and Thursday, 19 July. Tewkesbury Way will be closed between Mannington roundabout and Toothill roundabout between 9.30pm and 6.00am each night. If the project does extend for longer, for example, if we have bad weather, any further work will be carried out under lane closures.
Phase 3 – starting 23 July 2018
This phase will seek to improve the traffic flow from Great Western Way into Wootton Bassett Road (by Fish Brothers). In preparation for this phase, we will need to move some Vodafone and SSE cables out of the way before we make changes to the kerb line. BT cables running along Wootton Bassett Road will also need to be moved ahead of these works. The moving of the BT cables is planned to take place during the week commencing Monday, 23 July. This will be done under off peak lane closures between 9.30am and 3.00pm to minimise disruption and it is anticipated that it will take 3 to 4 days. Once this is completed, we intend to move the SSE and Vodafone cables before starting work to change the kerb line to its new alignment.
A further update will be provided once dates have been confirmed with SSE and Vodafone.
Phase 4 – starting January 2019
The final phase of the project will be based at Mannington Retail Park and will begin after the main Christmas period has finished. Construction of a new merging on-slip lane from the retail park onto Great Western Way will reduce the volume of traffic leaving the retail park at Wootton Bassett Road and entering Mannington roundabout. In the retail park itself, Telford Way, which is a public highway, will be widened and new traffic signs will be provided to make the internal flow much simpler and more effective.
Included in this scheme is a total refresh of all the road markings on the roundabout and a reduction of the speed limit both on the approach to Mannington Roundabout from Blagrove roundabout to 50mph, and on the exit from Mannington roundabout past the Retail Park to 40mph. This seeks to reduce the number of road traffic accidents in this area.
