A358 Taunton to Southfields

Closed 16 Jul 2017

Opened 28 Mar 2017


This consultation closed on the 16 July 2017. 

About this scheme

The A303/A358 corridor is the most direct main route between the south east and the south west. Tens of thousands of people use the route every day, including tourists on their way to some of the nation’s favorite holiday destinations.

But for now the road is not great at getting people from A to B. It is regularly congested and is frustrating for motorists who try to avoid tailbacks by diverting onto unsuitable local roads. This makes life hard for local communities too.

The aim is to transform the A303/A358 corridor into an expressway, a new type of strategic road which is as safe and reliable as a motorway and where ‘mile-a-minute’ journeys are the norm.

In its Road Investment Strategy, the government has identified eight separate sections of road along the A303 and A358 to Taunton where upgrades are needed, and has made funding available for the first three to get under way.

This website is about our public consultation on one of these schemes, the A358 Taunton to Southfields.

Why do we need this scheme?

The A358 between Taunton and Southfields roundabout currently comprises of a mix of dual and single lane carriageway, which leads to localised congestion, impacting adversely on journey times and journey time reliability.

We are proposing to create a dual carriageway link from the M5 near Taunton to the A303.

The proposed scheme provides a number of benefits to road users, businesses, the local community and tourists, they include:

  • relieving traffic congestion on a vital link to the South West peninsula
  • providing more reliable journey times
  • improving safety and reducing driver stress by providing a more free-flowing network
  • providing safer local access provisions for pedestrians, cyclists and other non-motorised users
  • helping the local economy to grow through the creation of a modernised and reliable road that reduces delays and makes the south west more accessible for tourism and business
  • supporting major development opportunities in the area south of Taunton through a proposed new junction at the M5 motorway (Junction A)
  • improving the environment by reducing pollution from queuing traffic, particularly during the busy summer months
