It runs east from Oban along the south bank of Loch Etive, through Lochawe and Tyndrum, Crianlarich, Lochearnhead, St Fillans and Crieff before passing through Perth, where it crosses the River Tay via Perth Bridge (West Bridge Street) to Bridgend.

It then runs concurrently with the A90 to the Swallow Roundabout, before diverging to follow the Invergowrie Bypass, Riverside Avenue and Riverside Drive before terminating in Dundee city centre.

The A90 road from Perth to Dundee was previously numbered A85;[1] on opening of an upgraded A94 to Aberdeen the A90 number was continued across the Friarton Bridge (previously M85) and on to the A85 route, then from Swallow Roundabout to Aberdeen.

[3] Some statistics seem to show that the stretch of the A85 between Oban and Tyndrum is among the ten most dangerous roads in Scotland.
