M27 Westbound closed, heavy traffic due to investigation works closing the A31 (at Ringwood) between J2 A36 / A326 (Romsey / Totton) and J1 A31 / B3079 (Cadnam), congestion on M27 to J3 M271 (Southampton Docks).
Following a serious crash on the A31 at Ringwood last night the M27 has been closed to divert traffic onto the yellow square route. Expected to be closed all morning. The A31 is open between Cadnam and Ringwood but only for local traffic.
Diversion - via A337 to Lyndhurst, A35 to Christchurch then A338 to rejoin the A31.
