The B8030 is a short loop off the A81 at Milngavie in East Dunbartonshire. It serves the town centre.
The route starts at Burnbrae Roundabout, where the northbound A81TOTSOs right and the B8030 takes over, running north along Main Street. Before long the B8050 comes in from the left at a signalised T-junction. Beyond the lights the B8030 widens to become a dual carriageway which soon becomes the Milngavie town centre relief road, which is known – beyond the point at which it curves away from the route's original course along the northern (town centre) part of Main Street – as Woodburn Way. The divergence is marked by railings on our left and a group of trees.
The relief road crosses the Allander Water by means of the Woodward Way Bridge, about 100 m south-east of the original Milngavie Bridge on Douglas Street (now pedestrian only). The new road and bridge both date from the mid-1970s. More traffic lights provide access to a Tesco store on the right, and then the road drops back to S2 past Milngavie railway station. As we curve round to the right on Woodburn Way, the B8050's original route along the now-pedestrianized Station Road comes in from the left, and so our road becomes the eastern end of Station Road outside the station. Just after passing the Town Hall, we return to the A81 and the route terminates at more traffic lights.
An amended OpenStreetMap trace for this route awaits uploading to the SABRE Wiki.
While the B8030 number was not issued in the original 1922 Road Lists, it seems probable that it was issued fairly soon after. While this could indicate that the A81 originally followed this route through Milngavie, the 1923 MOT map is quite explicit in showing the A81 on its present route. The fact that the B8030 number was issued before B8050 does, however, throw up an interesting point. Looking at an old map, it would seem logical to run the B8050 straight through to the A81. However, as that number was issued later, it must have always met the B8030 in the town centre, with the B8030 forming the loop that it still does.
