The new bridge, which carries the A814 was built as part of the Dumbarton inner relief road. It is a fairly typical late 20th century concrete structure which was built in 1972-5. There are 5 box girders across three spans carrying the roadway. It was built following the clearance for redevelopment of the Artizan area of Dumbarton, and provided a bypass for the narrow and congested old bridge. Despite the approaches from either side being dualled, the bridge is only a single carriageway. The A82 had long since been diverted to the north, but with so much traffic crossing the Leven every day all of the bridges were jammed with traffic at peak times.
