Drivers will see quicker, safer and more reliable journeys in Somerset under government plans to tackle congestion on the A303. The key route between Sparkford and Ilchester is being upgraded to relieve the over-congested road and create 30 miles of dual carriageway between Mere and South Petherton.

The £170 million plan is part of the government’s £15 billion investment in motorways and major A roads between 2015 and 2020 – the biggest in a generation.

More than 26,000 vehicles use this stretch of road a day, double the number it was designed for, and dualling the route will cut journey times and new junctions will enhance safety.

Transport Secretary Chris Grayling said: “Almost four million trips are made on the A303 every year and we are investing more than £2 billion to improve these motorists’ journeys, making them quicker and safer. Tackling congestion on this vital road will also help boost the economy in the south-west, unlock thousands of jobs and homes and promote tourism.” A consultation on building a tunnel for the A303 near Stonehenge is also underway. This will further improve journeys on the main road between London and the south-west. Further details on upgrading the A358 between Taunton and Southfields will also be revealed shortly.
