The A90 is a major road in Scotland. It runs from Edinburgh to Fraserburgh in Aberdeenshire.

From Edinburgh, it travels west and over the Forth Road Bridge, before turning into the M90 motorway. At Perth, the M90 again becomes the A90, now running north east to Dundee, Forfar, Brechin, Stonehaven, Aberdeen and Peterhead on its way to Fraserburgh.
