Dalmarnock Bridge (Railway) is a wrought-iron twin-track bridge on the Caledonian Railway (Dalmarnock branch) erected between 1859 and 1861. It comprised three tied-arch river spans of 70 ft and four 50 ft wrought-iron plate-girder land spans. The main girders were of bowstring construction 7 ft 712 in. deep at
the centre and crossed the river on a skew of 618 30’. Only its piers now remain. The engineer was George
Graham.An early example of pier founding using concrete-filled cast-iron cylinders sunk by open grabbing, in this instance to a depth of 14–22 ft below low-water level. There are three 512 ft diameter cylinders to each pier and five braced together at each abutment.
