The A39 is a key commuting route, with two key traffic light controlled junctions with the B3116 and A368 which have to manage over 5,000 vehicles per day. Congestion at these two junctions has an impact not only on through traffic but also in causing delays for local traffic. With the support from the Local Growth Fund, Bath & North East Somerset Council is improving these junctions to keep traffic moving and cut queue lengths which affect air quality.
What is happening?
The first improvement at the A39/B3116 junction (Two Headed Man) was undertaken in 2017. We are now planning improvements for the A39/A368 junction (Bences Garage). The existing signal controlled junction experiences long queues at peak times. It is proposed to widen the A39 southbound carriageway to two lanes, with separate lanes for ahead/left turn traffic, enabling more green time at the signals which is anticipated to reduce queue lengths.
What are the benefits?
Cutting the queues will speed up journey times, reduce emissions and alleviate pressure on minor roads which currently experience rat running.
When is it taking place?
Initial site setting up works will start after the August Bank Holiday weekend. The existing signals will be de-commisioned and replaced with temporary signals on Monday 3 September. The works are expected to take up to 12 weeks to complete.
