A steel gantry weighing 55t and measuring more than 50m long has been installed across the east and westbound carriageways of the M62 at Junction 23 to the east of Huddersfield.
The gantry spans over the six lanes and two hard shoulders of the motorway, and two lanes of the exit slip road of the junction. It was delivered to the site in two sections by steelwork contractor Briton Fabricators, then assembled on the ground and lifted into place by a 450t capacity mobile crane.
The gantry forms part of Birse Civils’ £11.8M project for the Highways Agency for works on the M62 Junction 22-25 upgrade. This includes new infrastructure along a 20km stretch of motorway which traverses the Pennines.
One of the key challenges in the scheme was the weather conditions on what is the highest motorway elevation on the national motorway network. Frequent changes in plan were necessary to deal with sudden changes in the weather.
