Bognor Northern Relief Road

The Bognor Northern Relief Road was part of the wider scheme to develop 1,350 new homes in Felpham and Bersted, north of Bognor Regis. The project involves the construction of a a viaduct structure over the floodplain and over the railway lines and Lidsey Rife watercourse. Additionally, an integral bridge carrying the service road and several culverts were constructed. Its value was £7.7m.

The structure comprises of 16 spans (33m long each), with only two expansion joints (at quarter-spans) supported on piers made of 5Nos 750mm columns each founded on 900mm CFA pile, up to 25m deep.

I have prepared the AIP for the bridge and all secondary structures (Lidsey Rife bridge and culverts) and I have undertaken the structural analysis of the viaduct using LUSAS. I have been also responsible for the design of all structural elements excluding the precast prestressed beams.
