This simple diagram shows WCC's intended route for an Eastern bypass.

Observe how Westbury is already surrounded on two sides by railway tracks.

An eastern bypass would go through fresh land.   The town would be encircled.

From the Northacre trading estate, south towards the A36, journey distance via the eastern A350 bypass to Madbrook could be doubled.   In the other direction, the severe congestion on the A350 at Yarnbrook would be made much worse.

The eastern bypass is routed the long way around to the industrial estates.  Many heavy goods vehicles would still be driven through Westbury.

Yet interconnection with Westbury Station, where both the London to Plymouth and Cardiff to Southampton main rail lines intersect, where a road-rail freight interchange is to be, is short-sightedly ignored by Wilts county councillors.
