The new Sunday’s Hill Bypass near Winchester, Hants, off the M27 is nearing completion with the bridge beams now in position. The photos show a 450 tonne mobile crane lowering each of the 10 pre-cast concrete beams onto the bridge abutments. The bridge abutments and wing walls are founded on over 125 piles and earthworks cuttings have been stabilised with soil nails.
NRP have project managed this infrastructure project on behalf of a consortium of house builders [Bovis Homes, Linden Homes, Bloor Homes] under an NEC3 ECC contract suitably modified for Design and Construction. Breheny Civil Engineering have undertaken the design and built the new relief road as part of a planning requirement for a new 1,400 home scheme in Boorley Green, Hampshire.
The new relief road links the southern reaches of Hedge End at Heath House Lane to the new Pylands Lane roundabout at Junction 8 of the M27.
The new road cuts through a brownfield site and opens up a further housing development along its length, whilst maintaining local flora and fauna habitat in the Hoe Moor Creek which is a small ravine. The bridge height is specifically designed to allow bats to fly under the bridge along the watercourse and above the bridge within the tree canopy.
Many planning and engineering challenges have been overcome to deliver the road, which is being adopted by Hampshire County Council.
The road is due to be opened to the public in Summer 2018.
