Friarton Bridge

The Friarton Bridge is a road bridge across the River Tay in Scotland. It is situated on the northeastern outskirts of Perth, approximately 25 miles upstream of the Tay Road Bridge. It is part of the M90 motorway, and is one of the northernmost sections of motorway in the United Kingdom. It forms part of the important east coast road corridor from Edinburgh to Dundee and Aberdeen.

The bridge spans the river, a row of electricity pylons, a number of warehouses and the A85 high above the surrounding plain.

It is a two-lane dual carriageway; unusually for a motorway (although not unusually for the M90) each carriageway has no hard shoulder. It was built in 1978, when it was designated as the M85 motorway. When the A85 from the north end of the bridge to Dundee was renumbered in the early 1990's to A90 through to Dundee, the motorway's designation changed to M90 to provide a continuous route number from Edinburgh to Fraserburgh.
