Cambuslang Road Underbridge

Cambuslang Road underbridge

The Cambuslang Road underbridge will carry both carriageways of the M74 over the existing Cambuslang Road. The section of Cambuslang Road beneath the bridge will be widened to allow for the location of the Cambuslang Road /M74 junction. This will be a ‘full diamond’ junction, with on and off slip roads to the M74 in both directions.

The four span bridge is supported at each end by reinforced concrete supports (abutments) and at three intermediate locations by multiple circular reinforced concrete columns (piers). The bridge deck (superstructure) is made up of precast concrete beams with reinforced concrete cast in place over the beams. Once the main superstructure is in place, follow on work (finishes) are required to complete the bridge parapets, to waterproof the bridge and to lay the road surfacing.

There will be some minor impact to traffic on Cambuslang Road during construction of the bridge, the erection of the bridge beams and the widening of the road but, generally, two-way traffic will be maintained at all times. Short overnight and/or Sunday closures of Cambuslang Road will be required when the bridge beams are being lifted into position.
