Emergency closure of M3 at Junction 9 after crash

The closure comes after a vehicle struck a safety barrier at Junction 9 early today (July 16).

In a post shared on Facebook by Winchester City Council, a spokesperson for National Highways said: "A vehicle struck the safety barrier at junction 9 this morning closing a lane.

"We need to complete urgent replacement of this barrier.

"We expect the closure tonight to take a few hours, but please be mindful it may be longer."

Drivers heading north should leave the M3 at Junction 9, take the A34 north to the A303 west.

Stay on the A303 until it re-joins the M3 at Junction 8.
