B830 Link in Dumbarton
Bonhill Road

The B830 is a relatively short road in Dumbarton, which seems to have been reduced in importance over the years.

We start on the A814, just to the west of the Retail Park, at a roundabout, although the original southern end of the B830 was further south at the other end of Church Street. Heading north from the roundabout is Townend Road, a road we shall come back to! Instead, we leave on Strathleven Place, heading eastwards, before curving to the north and passing under the railway - the bridge here was replaced in October 2018 during a 54hour operation, restricted by the need to reopen the railway line. Beyond the bridge, the B830 follows Bonhill Road, heading roughly north to the Bellsmyre Roundabout on the A82. Until recently, the A813 used to continue opposite, but it has now been moved further west to a new roundabout, the old road only serving Bellsmyre.

Now, you are wondering about Townend Road? Well, the strangest thing about the B830 is that it seems to have been quietly demoted. At the A814 roundabout, traffic is signed along the unclassified Townend Road in preference to Bonhill Road, and at the northern end, just before reaching the roundabout, the B830 actually has to give way to Townend Road. The explanation is fairly straightforward - Townend Road passes under the railway retaining its two-way width, while Bonhill Road has to manage with an S1 underbridge, forcing a pinch point and an 'oncoming traffic in middle of road' situation. The new bridge retained the same abutments, and so does not appear to have improved this situation.

Online mapping from Open Street Map is now showing Townend Road as the B830, and whilst West Dunbartonshire Council list the route described above, the list is from 2012, and 'currently being updated'. It is therefore unclear whether the route has changed or not.
