A ROAD crash caused rush hour traffic chaos on one of Dorset's busiest routes this morning.

One north-bound lane of the A338 Spur Road was closed after the one-vehicle collision half-a-mile north of the Blackwater Bridge at 6.15am.

Police initially closed both lanes on a stretch of the road but re-opened the offside lane in time for the heaviest traffic flow of the morning.

The road fully re-opened at 10am.

No details of the vehicle have yet been released and the condition of the driver is unknown.
