M9 closures: Motorists warned as two-month long roadworks to begin on major road

Motorists are being told to expect travel disruption over the next two months while a programme of works get under way on a major Central Belt road.

Overnight carriageway closures will be in place on the M9 from February 19 through to March 20, with a contraflow on the motorway 24 hours a day on Saturday, February 21, and Sunday, February 22, while BEAR Scotland conduct a major programme of resurfacing, bridge works and road marking improvements.

During the works, access for emergency vehicles will be maintained at all times.

Tommy Deans, BEAR Scotland’s South East Network Manager, said: “We’re co-ordinating a series of major improvement projects on the M9 to make the most of the carriageway closures that will be required and to ensure the motorway continues to provide safe and reliable service.

“The section of the M9 southbound that we are resurfacing this month is nearing the end of its service life and it is essential that we replace the road surface now before it deteriorates.

“A weekend contraflow is necessary due to the depth of construction. The works have a design life of 20 years.

“We recommend checking Traffic Scotland’s website and listening to the radio for journey time information.

“We’re grateful to motorists for their patience and understanding while we complete these improvements.”

What work is being done?

Works will start with a major project to renew 0.5 kilometres of carriageway on the M9 southbound near Linlithgow.

This will be followed by joint replacement works on two bridges between Junctions 5 and 7 – the bridge carrying the motorway over the River Carron and the bridge carrying the motorway over the railway near Grangemouth.

Road markings will be renewed on the M9 Junction 5 southbound off-slip, using the same carriageway closure as for bridge works.

The southbound carriageway of the M9 between Junctions 5 and 1A will then be closed for road marking improvements.
