Upgrade of the existing single carriageway road to dual two-lane carriageways with grade-separated junctions.

It avoids having to improve the A303 through the Blackdown Hills, but will increase the traffic load on the already-busy M5. Critics claim that it is inviting problems by concentrating all traffic for the south west on one long section of the M5.
