The M90 is a motorway in Scotland. It runs from Junction 1A of the M9 motorway, south of the Queensferry Crossing,^[2] to Perth. It is the northernmost motorway in the United Kingdom. The northern point goes to the western suburbs of Perth at Broxden. A small part of the M90 (across the Friarton Bridge to the southeast of Perth) was originally numbered as the M85 motorway.
