A road in Swindon is partially blocked due to a crash, causing traffic to build on the A420.

The crash occurred on Thornhill Road, just before the Gablecross Roundabout onto the A420, near White Hart Roundabout and was reported to the AA at around 6.40pm.

This has left the southbound side of the road partially blocked, resulting in traffic moving slowly heading onto the roundabout.

The AA have also reported slow traffic on the Gablecross Roundabout and coming off the roundabout onto Thornhill Road. This has backed up onto the A420 heading east from White Hart Roundabout.

In an update, the AA said: “Partially blocked and slow traffic due to crash on Thornhill Road southbound before A420.”
