C133 (South Lanarkshire)

This article is about the Class III road numbered C133 maintained by South Lanarkshire Council.
For other roads numbered C133, see C133.

The C133 starts on the A723 at Netherholm just south of Browns Bridge over the Avon Water. It then heads south west, loosely following the meandering river. Most of the time the road is high on the hillside, but as it crosses the tributary Dykes Burn, it runs along the bank of the Avon for a short distance. The C133 turns away from the river, into the valley of the Glen Gavel Water and meets the B745. After a short multiplex across the bridge, the route resumes, slowly converging on the infant Avon, until it reaches the Avon Bridge, which also marks the county boundary. The road itself continues the short distance to meet the A71 near Allanton Plains.
