Scheme Outline
Upgrade of M4 junction 13, where the A34 currently crosses the route. The plans will divert the A34 to the west of the junction on three miles of new dual carriageway to pass under the M4 without a junction, with the present dual carriageway through the M4 junction becoming a connecting road merging with the A34 at each end of the new section.
