The A813 is a short A-road in Dunbartonshire, running parallel to the A82 through Alexandria.
Dumbarton - Balloch
At its southern end the road used to commence at the Barloan Toll (sometimes known as Bellsmyre Roundabout); however, it now starts at a new roundabout junction with the A82 a little further west. Heading north as Stirling Road it passes the Bellsmyre housing estate before leaving Dumbarton and broadly following the course of the River Leven, passing the Strathleven Industrial Estate and the large housing estates of Redburn, O'Hare, Pappert, Braehead, and Beechwood before entering the town of Bonhill as Main Street.
Continuing north past the Bonhill Bridge, the road passes Napierston and goes through Jamestown, becoming Carrochan Road, before ending at a roundabout junction with the A811 in Balloch, close to Balloch Bus Station.

The original route of the A813
The A813 used to run west of Balloch to meet the A82 rather than south. It has essentially swapped numbers with the A811.
For more information on the history of the A813, see the A82/Great Western Road page, as the two routes have been inextricably linked.
