Viaduct work is complete at last
● puts a huge demand on the road surface and structure of the viaduct, so it’s important finishing works are completed to the absolute highest standards.
“We’re working hard to complete these elements, and remain on target to open the bridge this autumn.
“The work required in conducting concrete pours is highly technical, and I would like to thank everyone involved for their contribution.
“Each of them is playing a vital part in bringing Halton’s iconic new bridge to life.”
A range of specialist equipment has been used to build the North Approach Viaduct, including the 280-tonne wing traveller machine, which was used to build the outer road lanes on either side.
It followed Trinity, the 1,700-tonne, 157m long, moveable scaffold system, which built the central part of the carriageway.
The viaduct runs across the Widnes saltmarsh and will incorporate the roads for the entry and exit approaches to the Widnes side of the Mersey Gateway bridge.
Last month, construction of the bridge deck and stay cables also passed the halfway point, with construction moving forward at speed, ahead of the bridge opening this autumn.
Structural work continues on the South Approach Viaduct in Runcorn, which is expected to be finished in the summer.
Once complete, the two elevated approach viaducts will stretch across the saltmarsh on either side of the River Mersey, connecting the new bridge to the main road networks in Runcorn and Widnes. ●
