106 tonne concrete bridge beam lifted into place on Mersey Gateway project

Highways Reporters

The first of over 150 giant concrete beams has been lifted into place as work ramps up at a major road junction for the Mersey Gateway project.

A 550 tonne crane lowered the 106 tonne bridge beam into position at the Bridgewater junction in Runcorn, where the new Astmoor Bridgewater viaduct is being built over the Bridgewater canal. Two elevated slip roads are also being constructed.

This junction will form a key part of the new 9.2km link road, diverting traffic across the new Mersey Gateway Bridge to relieve congestion on the ageing Silver Jubilee Bridge.

Over the coming months, 156 beams will be placed between 24 bridge piers to create the base of the highway for the Astmoor Bridgewater viaduct and the two slip roads.

The giant beams measure around 40m long and weigh up to 106 tonnes – that's equivalent to the weight of 83 medium sized family cars.

Pre-cast in Ireland by specialist manufacturer Shay Murtagh Ltd, the beams are being shipped across the Irish Sea from Dublin to the Liverpool Docks and onwards to Halton by road.

Merseylink's south landside operations manager, Mike Davies, said: "This is a massive logistical operation as these heavy loads are nearly three times as long as a standard articulated lorry. We've done a huge amount of planning to ensure we can get the beams delivered safely to site with minimal disruption to local residents, commuters and businesses."

Richard Walker, Merseylink's Project Director, said: "Improvements to local highways are a key feature of this project and we are undertaking essential road infrastructure work at a number of major junctions in Halton. When it's finished, the new link road will provide a seamless route across the new bridge making it easier for people to travel between Runcorn, Widnes and beyond."

Councillor Rob Polhill, leader of Halton Borough Council and chair of the Mersey Gateway Crossings Board, said: "This is a hugely exciting moment for the project. Already we can see the pylons for the new bridge emerging from the river and now we will be able to see the brand new road network taking shape. I would encourage everyone to keep an eye on the website gallery and social media to see the rest of the beams make their way through Halton and get lowered into place."

The new bridge is scheduled to open in the autumn of 2017.
