M90 motorway

The M90 is a motorway in Scotland. It runs from Inverkeithing, at the north end of the Forth Road Bridge, to Perth, passing Dunfermline, Cowdenbeath and Kinross on the way. It is Scotland's - and the UK's - most northerly motorway, the northernmost point on its spur into the western suburbs of Perth at Broxden.

The M90's arguably most impressive engineering feature is the Friarton Bridge in Perth, a tall concrete pillared structure which traverses the River Tay. The bridge carries eastbound traffic from Broxden towards Dundee and along the Firth of Tay.

The road constitutes most of the southerly part of the crucial A90 corridor from Edinburgh, through Perth, Dundee and Aberdeen to Fraserburgh along Scotland's North Sea coast.

The M90 is considered one of the UK's most sub-standard motorways. Junctions 1 and 2 share a tiny common sliproad, forcing a conflict between entering and leaving traffic at the junction with the A823(M). It lacks hard shoulders for an eight-mile section. In this section there are lay-bys at quarter-mile intervals instead. The M90 also has the tightest corner on the UK motorway network, for which traffic is forced to slow.

Near to its northern terminus, the motorway splits into two branches. One branch forms part of the western bypass of Perth, and meets the A9 at its end. The other branch heads in a north-easterly direction, flowing into the A90 at its end. The easternmost branch was formerly the M85 motorway, until the A85 was renumbered as A90.

The M90 forms part of Euroroute E15 which runs from Inverness to Algeciras.
