The route of the A303 has been changed a couple of times. The oldest route passes through the centre of the village past the Old Inn, and is a narrow lane. The village was bypassed by a new route a hundred yards to the north, and has since been bypassed again by the creation of a dual carriageway a few yards further north. To reach Holton it is necessary to leave the modern A303 at Wincanton (2 miles to the east) or, if arriving from the west, leave at Blackford (1 mile to the west), then join the older route.
Governance
The parish council has responsibility for local issues, including setting an annual precept (local rate) to cover the council’s operating costs and producing annual accounts for public scrutiny. The parish council evaluates local planning applications and works with the local police, district council officers, and neighbourhood watch groups on matters of crime, security, and traffic. The parish council's role also includes initiating projects for the maintenance and repair of parish facilities, as well as consulting with the district council on the maintenance, repair, and improvement of highways, drainage, footpaths, public transport, and street cleaning. Conservation matters (including trees and listed buildings) and environmental issues are also the responsibility of the council.
