BEBO Arch, Heysham Bypass
Moore Concrete are proud to have been awarded the prestigious Certificate of Excellence at the 2015 Concrete Society Awards for The BEBO Arch at Heysham Bypass. The precast concrete units Moore Concrete manufactured were described by the main client Costain International as having “the best finish they’d seen on a precast bridge.” Moore Concrete made the arches for Asset International who are exclusive UK & Ireland Licensees for the BEBO ARCH system.
The BEBO Arch at Heysham Bypass, also achieved notoriety as it is currently the largest precast over fill arch in the world!
The T94 Arch Bridge Structure installed over the Milestone Canal, features a clear span of 28.6 metres at a rise of only 3.2 metres, and a total length of 36.735 metres using 60 individual precast units.
The units weighed 19.8 tonnes each and are joined by an insitu stitch at the crown and held at the bottom by a reinforced concrete footing strip on either side of the canal.
Custom made steel moulds were used to create the arch by local steel engineers KME.
The Concrete mix design was required to be a high specification 50% GGBS mix using self-compacting concrete. We developed a mix design that offers increased durability, reduced permeability, increased strength, lower heat of hydration, high resistance to chloride penetration, high resistance to sulphate attack and a lighter colour.
The majority of the environmental impact of concrete provided at the construction site derives from cement. Using GGBS as a partial replacement for Portland cement yields significant improvements in the environmental performance of concrete and is an important part of sustainable developments in concrete production.
The Heysham to M6 Link Road completed the long awaited connection from Heysham to the Morecambe Peninsula from Junction 34 of the M6, and will be a 4.8km dual carriageway with a footpath and cycleway along the entire route. The project involved the fully remodelled junction 34, with new slip roads, a new bridge over the River Lune and a 600 space park and ride site. The new road provides better access for residents, businesses and tourists to the area. The new road brings huge economic and transport benefits to the county. As well as easing congestion caused by traffic traveling through Lancaster city centre, the link road greatly increases the potential for future investment in the surrounding area
