|Route outline (key)|
The B825 is a medium-length B-road in the Central Belt. The road was originally unclassified but had gained its present number by 1932.
The road starts on the A89 on the eastern edge of Caldercruix and heads north, going under the Edinburgh to Airdrie railway line almost immediately. We pass to the east of the village, with a couple of roads leading there from the B825 before we bear right to head across country. A largely straight road is followed across grassland, until we bear sharply left to enter Limerigg, where we meet the B8022.
The road briefly skirts the Black Loch before climbing across the fields. The other end of the L-shaped B8022 is then met, after which the road descends to cross a small stream and enter Avonbridge. We meet the B8028 at a T-junction and that road is then the dominant partner in a multiplex through the village centre and across the River Avon. The B825 regains its number by turning right by the church. It soon leaves town and goes over a hill before passing through Standburn to reach a large roundabout on the A801 and B805.
We continue ahead and cross a narrow bridge over the Union Canal before a few bends take us to pass south of Whitecross. Soon we go under the Edinburgh to Falkirk railway line which is on a viaduct at this point; we zigzag through one of the arches. After leaving the railway the road returns to the River Avon and runs alongside to end at a T-junction on the A803 (former A9) immediately to the west of that road's bridge over the river.
