City Union Railway Bridge

The City Union Bridge is a bridge on the River Clyde in Scotland. It was opened in 1899. It was once a busy main route in and out of St Enoch station but that terminus closed in 1966 and was demolished in 1977, and since then the bridge is only used for empty stock movements, as the bridge forms a key link between Glasgow Queen Street and Glasgow Central. If a project known as Glasgow Crossrail goes ahead then the bridge and associated track will see passenger services once more.

The City of Glasgow Union Railway built the first railway bridge over the River Clyde in the City of Glasgow here, which opened in 1870. It consisted of twin-lattice parallel iron girders in seven spans; the engineers were John Fowler and J F Blair, and the contractor was Thomas Brassey & co. Deep foundations to the piers required—up to 100 feet—and cylinder caissons were lowered to firm rock by the use of a grab type excavator working within; the excavated face was kept under water.
