Junction options


The consultation also sought views on junction provision. Three options were shown for junctions to provide access to Winterbourne Stoke as follows:

  • Option 1 - one-way junctions with the existing A303 at each end of the village

  • Option 2 - an all movement junction with the B3083

  • Option 3 - a half junction with the B3083 for eastbound traffic and single slip roads to the existing A303 at each end of the village for westbound traffic

Three options were put forward for the improvement of Longbarrow crossroads, an improved at-grade roundabout, a conventional grade separated junction and a half-cloverleaf junction to the west of the A360.

In addition three possible options were suggested for the improvement of Countess roundabout. These were, signal control of the existing roundabout with the A303 taken through the centre of the main island, signal control of the existing roundabout with adjustments to the carriageway and lane widths and grade separation.
