Schedule 2 MAJOR STRUCTURE

The bridge carries the A69 Haydon Bridge Bypass over the Newcastle to Carlisle railway line, an access track alongside the railway and the River South Tyne and comprises a four span composite steel girder and insitu reinforced concrete slab deck supported on insitu reinforced concrete abutments and intermediate insitu reinforced concrete pier supports.

The four spans will be 42.5m, 39.7m, 41.5m and 41.75m measured on the centreline of the bridge. The bridge will be skewed at 50 degrees to the river supports and at 57 degrees to the railway supports. The deck will be continuous over the piers and fixed at the west abutment and with a movement joint at the east abutment and supported on bearings at the abutments and piers.

The overall width of the structure varies along some of its length due to the taper required for a traffic ghost island proposed to the west of the viaduct. The deck is a constant width of 11.80 metres from the east abutment until approximately Chainage 470m where it starts to widen towards the west abutment to a width of 13.70 metres.
