A NINE vehicle pile-up is causing traffic chaos on the A303 and M3 this morning - with experts predicting delays of up to two hours.

The crash happened earlier this morning, near to the junction between the M3 and the A303.

One lane of the road was closed, but has since been re-opened.

There are also long delays on the M3 southbound before junction eight, for the A303, and slight northbound delays due to drivers slowing to look at the incident.

Hampshire's traffic management service, ROMANSE, is warning of two hour delays on the M3 southbound.
