|Route outline (key)|
As with all B76x roads, the B766 is an urban B-road in south Glasgow.
The road starts on the B768 in Battlefield at traffic lights opposite the Victoria Infirmary and then heads eastwards along Battlefield Road (the former A727) to go under a railway line and reach another set of traffic lights, where it TOTSOs right. The next set of traffic lights mark the original northern end of the road. From here it goes along King's Park Road to traffic lights. Originally it then turned right along Carmunnock Road under its railway bridges; now, however, it continues ahead to traffic lights. To the left is the A728 and the other two directions are B762. There is a short multiplex to the right along the B762 under a railway line before that road turns right at the next set of traffic lights and the B766 continues ahead. A short distance further on is a roundabout where the B766 joins its original route once more.
The road continues south and skirts King's Park. After a roundabout the road becomes dual-carriageway and runs to the west of Castlemilk, with no houses now opening onto the B766. Eventually another roundabout is reached. Originally the B766 continued ahead into Carmunnock, where there was a short multiplex along the B759. Now, however, the village is bypassed to the west and the B759 is crossed at a roundabout. The southern end of the bypass is reached and the B766 ends just afterwards at a roundabout on the A727 (former A726) to the north of Thorntonhall. For a few years after the A726 Glasgow Southern Orbital was built it was the A727 which ended here and the B766 turned left to end on the GSO on the western edge of East Kilbride. Logic has now won and so the B766 has returned to its original southern end.
