Removing trucks and cars from Cleveland Bridge, Bath

Build a simple, low cost, SLOW bypass, not the usual over designed high speed and obtrusive multi-lane type to connect trucks and cars from the M4 and Chippenham directly to the A36 rather than the present route through Bath which creates massive pollution and is destroying the Cleveland Bridge.
