The road is mostly a two-lane single carriageway and runs through residential and some industrial areas upon reaching its northern end.

Beechboro Road South commences as a continuation of Whatley Crescent at a traffic light controlled T-junction with Rose Avenue in the Bayswater town centre.

Following this flyover the suburb is now within the residential suburb of Bennett Springs, encountering a roundabout with Orchid Avenue and Bridgeman Drive and a T-junction with Bennett Springs Drive, all within 750 metres (2,460 ft) before intersecting with Marshall Road at traffic lights.

After 0.3 kilometres (0.19 mi) beyond Marshall Road the road encounters a roundabout providing access to Ballajura railway station and then crosses over the upcoming Ellenbrook railway line (as part of the Metronet project) 0.4 kilometres (0.25 mi) further.

Beechboro Road North ends at a roundabout interchange with Tonkin Highway, continuing westwards as Hepburn Avenue.

[2] The southern terminus of Beechboro Road South was later realigned during the rebuild of Bayswater railway station in 2023.

Prior to the rebuild Beechboro Road South commenced as a continuation of Railway Parade 200 m east of a traffic light controlled T-junction with Coode Street in the Bayswater town centre.

Since the rebuild of Bayswater as an elevated train station Beechboro Road South now connects directly under the line to Whatley Crescent.
