|Route outline (key)|
The road starts at Bog Roundabout on the A9 in Laurieston. There's a brief D2 section south to the next roundabout, where we cross the A803, after which the road narrows. We then run alongside the Edinburgh to Stirling railway line across a roundabout and a burn and finally cross the line in Westquarter. The Glasgow to Edinburgh via Falkirk line is then crossed and we pass a Tesco before going over the Union Canal.
The road now skirts the southern edge of Polmont. We pass the YOI and then meet the B810 at a roundabout, after which there's a brief multiplex until that road regains its number by turning left. We continue vaguely southwards through Maddiston, after which a brief rural section takes the road to its terminus at the large Bowhouse Roundabout on the A801 and B825.
