BAM became the first construction contractor in Scotland to use 3D printing to create the staircase for the bridge, which will provide access on the southside of the new structure.

Once installed the steps were clad in granite to give a long-lasting and slip-free finish.

The main span of the new structure was installed during a 14-hour closure of the M8 motorway in summer 2021. The 2,420-tonne structure was pirouetted into place by BAM and heavy lifting specialist Mammoet.

The weathered appearance of the structure is a key part of its design. It aims to reduce maintenance costs and reflect both the area’s industrial heritage and the front of the local St Martin’s Primary School campus. It was manufactured using Cor-Ten steel.

BAM contracts manager, Ian Steele, said: “The project has pushed the boundaries of what’s possible within construction, using cutting-edge digital techniques and collaboration from everyone involved. We are proud to leave a sustainable legacy that will benefit the north of Glasgow for years to come.”
