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 was recognised as an impact not only on through traffic but also in causing delays for local traffic. In 2017 and 2018, with the support of a grant from the Local Growth Fund, Bath & North East Somerset Council is improving these junctions in a two-stage process which will significantly reduce queue lengths. The first improvement at the A39/B3116 junction (Two Headed Man) was undertaken in 2017, with the A39/A368 junction (Bences Garage) being delivered in early 2018.


Two Headed Man junction – completed November 2017

The light-controlled junction at the Two Headed Man used to feature one lane in each direction. Vehicles turning here held up traffic while they waited for the opportunity to turn. Modelling showed that widening the carriageway of the A39 on each approach to two lanes and providing dedicated turning lanes would substantially reduce peak time queues. The changes have significantly improved both capacity and flow at the junction, improving journey times and reducing emissions.

Bences Garage junction – 2018

This three-armed junction has traffic flows of around 1800 vehicles per hour at peak times. The current junction’s layout cannot manage the levels of traffic flowing through it and significant queues result.

The improvements will see the southbound carriageway widened to accommodate two lanes, with separate ahead and left turn options. A drop-in session will be taking place at Marksbury Village Hall on 27 March between 5.30pm and 7pm. More information will be published on this page as it becomes available.
