Route of the A417 and A419

One of the few new cross-country routes created in recent years, the A417 and A419 together form a strategic link between the M4 and M5, connecting Swindon, Cirencester, Cheltenham and Gloucester, and longer distance destinations via the two motorway corridors.

Because this route seems only to have had attention paid to it relatively recently, it's not quite finished. For the A417's part, the obvious gap is near the Gloucester end, specifically around the Air Balloon Roundabout. Here the road becomes single carriageway for three steeply sloped and twisting miles, culminating in the roundabout at the bottom of the hill where the road doubles back on itself. The Highways Agency now has plans to fix this — but it won't be an easy job.

Further south on the A419, there's a new bypass of Blunsdon and a flyover at the Commonhead roundabout planned. Along with the scheme above, this will finally make the route a grade separated dual carriageway right the way from Swindon to Gloucester.
