A major programme of works to refurbish the deck of a bridge carrying the M9 motorway over Bonsyde Road near Linlithgow is due to commence on Monday 30 June.
The works are expected to last for three months and will require lane restrictions on the M9 between Junctions 3 and 4 as well as a series of overnight closures.
The hard shoulders of the motorway will be used to ensure that two lanes in each direction remain open to traffic, however a 40mph speed limit with continuous alternative lane closures and a contraflow will be in place throughout the works.
The first overnight closure is planned for the night of Monday 30 June between 20:00 and 06:00. A diversion route will be signposted in both directions between Junctions 3 and 5, via the A904, the A993 through Bo’ness, the A904 and A803, adding an estimated 1.5 miles and ten minutes to journey times.
Details of further overnight closures will be announced when timings are confirmed.
The local road underneath the bridge will not be affected by the works.
Consultation has taken place with relevant stakeholders in advance of these works to make them aware of the traffic management arrangements and to minimise any inconvenience.
David Bishop, BEAR Scotland’s South East Unit Bridges Manager, said: “This programme of refurbishment is essential to preserve the structural integrity of this bridge and extend its service life for decades to come.
“The works have been planned to minimise disruption to road users as far as possible. Although a reduced speed limit and lane restrictions will be in place, we’ll keep two lanes open in each direction and do not expect traffic to experience significant delays.
“Some overnight closures are however unavoidable, to allow for the installation and removal of temporary safety barriers.
“We’re grateful to motorists for their patience and understanding.”
