The first deck span has been completed for the elevated north approach viaduct of the £1.9bn Mersey Gateway.
The 60m long, 18m wide structure forms part of the six-lane toll bridge between Runcorn and Widnes being built by the Merseylink consortium.
A 34-hour, 1,146m3 concrete pour was required to build the span, using a movable scaffolding system (MSS) named Trinity.
Merseylink general foreman Declan Cannar said: “This is a real achievement for the project and a milestone that we’ve been looking forward to with anticipation. Our construction teams have put a considerable amount of time and effort into constructing this initial span so it’s great to see it finished. We’re now busy preparing the MSS so it’s ready to cast the next section.”
New Civil Engineer last year reported in depth on the seven stages of the Mersey Gateway project.
