• Overnight carriageway closures 5 to 7 November 2025

• Full practice deployment in early hours of 9 November 2025

A series of overnight carriageway closures is planned on the M90, to allow routine servicing and maintenance of the automated barriers that direct motorway traffic over the Forth Road Bridge if the Queensferry Crossing needs to close. This will ensure the system is fully operational and ready for winter.

On the nights of Wednesday 5 and Thursday 6 November between 22:00 and 05:00, the northbound carriageway of the M90 will be closed next to Junction 1B Ferrytoll, to allow the system on the north side to be serviced. Northbound traffic will be diverted down the Ferrytoll off-slip and immediately back onto the M90 via the Ferrytoll on-slip.

On the night of Friday 7 November between 22:00 and 05:00, the A90/M90 will be closed in both directions between Scotstoun and Queensferry Junctions, to allow maintenance and servicing of the barriers on the south side:

• Southbound traffic will be diverted from Junction 1A Queensferry via the A904 to Echline Junction, then via the southbound Public Transport Link onto the A90 into Edinburgh, Maybury Road and Glasgow Road to M9 Junction 1 Newbridge.
• Traffic joining the M90 northbound from the A90 will be diverted up the northbound Public Transport Link then onto the B800 towards Echline Junction, the A904 and Queensferry Junction.
• Traffic wishing to join the M90 northbound from the M9 eastbound will be diverted off at M9 Junction 2, onto the B8046 and then the A904 to M90 Junction 1A Queensferry.
• Traffic wishing to join the M90 northbound from the M9 westbound will be diverted on to M9 Junction 3, and then back eastbound to exit at M9 Junction 2, onto the B8046 and then the A904 to M90 Junction 1A Queensferry.
• The M9 Junction 1B Winchburgh eastbound on-slip will be closed, with traffic diverted from M9 Junction 3.

In the early hours of Sunday 9 November between 00:01 and 04:00, a full practice deployment of the diversion system will be undertaken to ensure all elements are in operation. Traffic in both directions on the M90 will be diverted over the Forth Road Bridge.

David Bishop, BEAR Scotland’s South East Unit Bridges Manager, said: “The automated barrier system on the M90 significantly reduces the time it takes to open a diversion via the Forth Road Bridge, should the Queensferry Crossing need to close for any reason.

“These overnight closures will allow us to test the system and identify and address any issues so that it is ready to be used if required this winter.

“It is important that road users comply with red X signs above the carriageway when these appear, as the diversion route cannot be opened until traffic on the motorway has stopped.

“If there are red X signs above all lanes, you must come to a stop.”

Road users using the Queensferry Crossing or Forth Road Bridge during these works are encouraged to plan ahead by checking the Traffic Scotland website www.traffic.gov.scot for up-to-date travel information and allowing extra time for their journey.
