Monkey Island Bridge Project
Collett deliver a series of paired girder sections to construct the M4 Monkey Island Bridge project.
Over a series of weeks Collett deliver several bridge sections from Cleveland Bridge’s Darlington site to the Monkey Island development project in Berkshire. Ranging in length from 15m to 36m, and weighing 26 to 63 Tonnes, Collett delivered each of the paired girders the 295 miles to the delivery site.
Utilising specialist extendable flat trailers, our Team loaded each of the lengthy cargoes at their Darlington manufacturing facility ready for the journey south to the Slough construction site. With three at 26 Tonnes, three at 53 Tonnes and three at 63 Tonnes, our Team transported the loads in multiple convoys to site, providing timed deliveries to suit road closures already in place. Two of each were delivered in advance to the site compound for pre-erection prior to the last three of each of the loads being delivered directly to the M4 weekend motorway closure when the completed bridge was finally installed.
Fabricated by Darlington based Cleveland Bridge, Collett successfully delivered the nine braced pairs to site before being assembled and installed during a 54 hour period.
Each of the girders once constructed will form an 82m long, 400 Tonne steel bridge at Monkey Island as part of a major upgrade of the M4 motorway between junctions 3 & 10. The bridge forms part of a scheme that will eventually see a total of 11 bridges replaced along the M4 in Berkshire as the highway is upgraded to a smart motorway.
