A canal bridge and an invisible Roman post share the Glasgow Bridge site at Kirkintilloch. Glasgow Bridge includes a Roman fortlet (a small frontier fort) on the Antonine Wall, identified from aerial photographs rather than excavated remains.
The place is a useful overlap of Roman and canal history. Road users cross the Forth and Clyde Canal here, while cropmarks and photographs preserve the outline of a frontier post that can no longer be made out on the ground.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
The road bridge was built as a swing bridge and now carries the A803 across the Forth and Clyde Canal.
The bridge was reinstated in the 1990s when the canal reopened.
The Roman fortlet site has appeared in aerial photographs taken at various times since 1955.
The fortlet has not been excavated, so its interpretation depends on aerial evidence.
The fortlet lies between the Roman forts at Kirkintilloch and Cadder.
