|Langbank Roundabout and Dumbarton Rock|
Langbank Roundabout lies on the A8 just over 1km west of the terminus of the M8. As such, it is the first interruption to free flowing traffic after the end of the motorway. The A8 here is a dual carriageway, and has been built out along the shore to replace the old line which runs through the small village of Langbank. The roundabout connects the two, the old line of the A8 now being the B789 eastwards to the old junction between the two, whilst the old Greenock Road through Langbank is also sometimes numbered as the B789 this appears to be an error.
There are only 3 exits from the junction, the River Clyde preventing any road to the north. Immediately south of the roundabout, the road into Langbank takes priority, with the B789 therefore (probably) TOTSOing to the left. The old road runs west parallel to the new A8, between it and the railway, before rejoining at a junction with the westbound carriageway only further west. There are also two side turnings which cross the railway to reach the rest of Langbank on the hill above.
