Edinburgh roads: Overnight closures at M90 near Queensferry Crossing as automated barriers get serviced

The M90 will be closed in both directions north of the bridge next to Ferrytoll Junction between 10.30pm and 6am each night from Monday, October 21 to Saturday, October 26.

From October 28 to November 2, the motorway south of the bridge between Scotstoun and Queensferry Junctions will be closed in both directions between 10pm and 6am each night.

The final part of the project will see two full trials of the diversion system carried out with traffic in both directions rerouted over the A9000 Forth Road Bridge. This work will take place on November 9 and 10 between midnight and 8am. 

BEAR Scotland

David Bishop, BEAR Scotland’s south east unit bridges manager, said: “The system of automated barriers that we have installed 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.

“This autumn we’ll be servicing the system during overnight road closures and there will be two full overnight trials of the system. It is important that road users comply with red X signs above the carriageway when these appear, as the diversion cannot be opened until traffic on the motorway has stopped.”

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

The automated moveable barriers were installed in 2023 and ‘intelligent road studs’ that light up to guide motorists onto the diversion route were installed earlier in the year. BEAR Scotland advised a previous trial carried out in April saw the new diversion system was deployed in 19 minutes.
