|Junctions related to the A358|
Southfields Roundabout, also known as Horton Cross, is the junction between the A303 and A358. The B3168 also connects to this roundabout. It is particularly busy as it is the link between Taunton and the M5 (via the A358) and the A303, which provides access to the M3 and eventually London. Plans have been released to upgrade this junction, but little progress appears to have been made.
