This short length of the A90 was required at this point as motorway regulations would have prevented certain classes of traffic from using this section of road.

The crossing opened as part of the motorway on 30 August 2017; the bridge is configured as a dual two lane carriageway and has a speed limit of 70 mph (110 km/h).

[9] Previously, the M90's most substantial engineering feature was the Friarton Bridge in Perth, a tall concrete pillared structure which traverses the River Tay.

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

A large part of the northern section of the motorway follows the route of the former main railway line between Perth and Edinburgh via Glenfarg, Kinross and the Forth Bridge, which was closed in 1970 despite this not being recommended by the Beeching report.

The Kinross and Milnathort Bypass, the 8-mile (13 km) section of the M90 between Fruix and Arlary, was the first motorway in Britain to be constructed using concrete pavements that were not reinforced.

The Broxden to Muirmont slip road at the centre of the interchange has a radius of 136.4 m (448 ft), necessitating maximum superelevation of 7%.

This corner also coincides with one of the steepest sections of the motorway,[12] for which north-bound HGVs are sign-posted to stay in a low gear and often brake continuously through the turn.
