To facilitate the installation of road lining over the recently refurbished bridge deck, the M9 westbound will be closed overnight between junction 3 and 4 near Linlithgow from 8pm on Friday, October 25 until 6am on Saturday, October 26.

Westbound traffic will be directed to leave the M9 at junction 3 and follow the A803, the A904, the A993 through Bo'ness, the A904 and the A905 to re-join the M9 westbound at junction 5. This will add an estimated 1.5 miles and ten minutes to journey times. The local road underneath the motorway will not be affected.

With the lining set to be finished on Saturday, October 26, this will signal the completion to a two month long refurbishment of the deck of the bridge carrying the M9 motorway over Bonsyde Road.

David Bishop, BEAR Scotland's South East Unit Bridges Manager, said: "The refurbishment of this bridge is essential to preserve its structural integrity and extend its service life for decades to come.

"Installing the road markings is final stage of the programme and means the project comes to an end on Saturday morning. We're grateful to road users for their patience and understanding while we undertook this project."

Motorists are encouraged to plan ahead before setting out by checking the Traffic Scotland website for up-to-date travel information and allowing extra time for their journey.
