The A303, a major road through southwest England, passes through the village. A bypass, called the Marsh Diversion, opened in 1976.[2][3] It is the only section of the A303 to be upgraded to dual carriageway through the Blackdown Hills. As a result, the village has also been mentioned in several strategic route plans, including the "Ilminster to Marsh improvement" and "Marsh to Honiton improvement".[4]
