One of the Ring Road’s busiest roundabouts could be turned into a £5.9m ‘throughabout’

Plans to create traffic lanes through the notorious Wraxall Road roundabout on the Ring Road at Warmley – and signalise the roundabout – have gone out for public consultation.

The junction with Tower Road and Wraxall Road is currently the only one on the A4174 Ring Road without traffic signals.

The roundabout, also known as the Woodstock roundabout, currently experiences congestion during the busiest hours on weekdays, with queuing causing delays to traffic on the Ring Road and also vehicles entering the roundabout using Tower Lane and Wraxall Road. This includes local bus services.

The delays are expected to increase as traffic levels grow, due to the extra housing and jobs planned for the Bristol area.

About five years ago a traffic lights scheme was considered for the roundabout but that was ruled out after analysis by South Gloucestershire Council’s highway experts showed the roundabout was too small to accommodate queuing traffic on it and that traffic lights would make the problems of queuing on Wraxall Road and Tower Lane worse.

Screening has since been installed to reduce the “excessive visibility” on the ring road approaches in order to slow ring road traffic coming up to the roundabout, so reducing accidents and giving the side road traffic an easier entry onto the roundabout.

This new £5.9m improvement scheme involves works to convert the existing roundabout into a fully signal controlled ‘throughabout’ – a roundabout with lanes running through the middle of it. It includes widening of the roundabout approaches into the verge to provide three lanes for the straight ahead/through movements.

The objectives of the improvement scheme are to:

  • Reduce the number and severity of collisions at the roundabout;
  • Improve traffic flow along the A4174 Ring Road and reduce delays on approaches to the roundabout;
  • Improve air quality in the vicinity of the roundabout;
  • Maintain capacity, or reduce delays where possible, on the Wraxall Road and Tower Road approaches; and
  • Enable growth from housing and other development schemes.

The idea is part of a wider package of improvements to Ring Road junctions proposed in the draft Joint Local Transport Plan 4 (2019 – 2036) for the West of England.

The West of England Combined Authority has approved the outline business case for a preferred scheme. Public consultation on this will support the development of a full business case, which is required for funding to be secured to deliver the scheme. Construction is subject to receiving funding and a date for construction is yet to be determined.


The council is holding two drop-in sessions at Warmley Community Centre where plans of the scheme will be on display and representatives from StreetCare will be present to answer questions. The first is on Wednesday 6th March from 5pm to 7pm and the second is on Wednesday 13th March from 5pm to 7pm.
