It is located on the outskirts of Perth, and is one of the city's two major roundabouts – the other being Inveralmond Roundabout, where the A9 meets the A912 Dunkeld Road, 2.3 miles (3.7 km) to the north-northwest.

The roundabout, oval in shape, is an important hub of the Scottish road network, a major junction on the A9 north–south route, and the UK's northernmost motorway junction, being junction 12 of the M90 motorway.

Broxden is an interchange for several local bus and long-distance coach services, the latter provided by Scottish Citylink, Megabus, FlixBus, and Ember.

There is a park and ride area with a local bus service to Perth city centre.

The roundabout was originally designed with the future intention of connecting the northbound A9 and the M90, with the roundabout being replaced by a grade separated junction, and in 2008 Transport Scotland published proposals for the dualling of the A9 between Dunblane and Inverness including the replacement of Broxden Junction with a flyover.
