Watch: Timelapse video of bridge demolition over A90

That means there will be road closures around the south end of the Forth Road Bridge between Saturday evening and Monday morning.

Work started last weekend and Transport Scotland has released a video showing last weekend’s work to remove the B800 flyover.

This weekend work will start at 8 pm on Saturday and continue until 6 am on Monday morning. During that time the A90 and M90 (M9 Spur) will be closed.

Diversion routes to cross the Forth for A90 traffic travelling south and north will be via the M9 (A904/5 for non-motorway traffic), Kincardine Bridge and the A985 to Rosyth and further afield. Diversion routes for traffic travelling north from Edinburgh will be via the M8 and M9 to Kincardine Bridge.

The road closure will be in place between Echline Junction, south of the Forth Road Bridge and north of Barnton at the B924 Dalmeny junction on the A90. In addition, the M90 (M9 Spur) will also be closed in both directions between M9 Junction 1A and the A90 Scotstoun Junction at Queensferry. The B800 and B924 will remain open for local access only.
