The A85 is a major road in Scotland. 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. Its name between the latter two locations is the Crieff Road. It then multiplexes with the A90 to the Swallow Roundabout before diverging to follow the Invergowrie Bypass, Riverside Avenue and Riverside Drive before terminating at the Riverside Roundabout where it meets the A92.
