Diversions in place
Drivers of vehicles under 4.2 metres are being directed off the M4 at Junction 16 and should follow the Solid Diamond diversion symbol. The diversion takes traffic towards Royal Wootton Bassett before using the B4042 through the area of The Common and Brinkworth. Motorists then join the A429 and continue towards Junction 17, where they can rejoin the M4. A separate diversion is operating for vehicles measuring 4.2 metres or taller. Those vehicles are being directed via the A3102 towards Royal Wootton Bassett and Calne, before travelling along the A4 towards Chippenham and joining the A350 northbound to reach M4 Junction 17. National Highways said motorists affected by the closure should allow extra journey time, consider alternative routes or delay their journeys where possible. The nature of the collision and details of any casualties have not yet been confirmed. There is currently no confirmed time for the motorway to reopen. This is a developing incident, and UKNIP will provide further updates as information becomes available.
