The B919 – a short link road in Kinross-shire – starts in Wester Balgedie, where it turns off the A911 by the Balgedie Toll Tavern to head off northwestward, descending as it does so, steeply at first. To begin with, it runs dead-straight but becomes more winding as it nears the bottom of the hill. Here the road crosses a dismantled railway line adjacent to the former Mawcarse station, which is just recognisable although very little now remains of it. The road then continues for a short distance across the fields to end on the A91 just to the east of the south-facing M90 J8.
Originally the B919 continued ahead, crossing the A91 and following the course of what is today an unclassified road for a little over 300 m to end at a second crossroads, with the old A90 (long since replaced by the M90). The coming of the motorway completely altered the road layout in this area, however, and all that now marks the site of the B919's original terminus is a sharp bend to the right in the present minor road, all trace of the former roads to left and straight ahead having totally disappeared from the landscape.
An amended OpenStreetMap trace for this route awaits uploading to the SABRE Wiki.
