From Warminster And District Archive magazine, No.4, May 1990:
Bradley Bridge
This overbridge carries Bradley Road (an unclassified road) over the Bypass. The crossing is square to the Bypass and the road over is at an incline of 1 in 40. The deck consists of a 3 span continuous reinforced concrete slab with 1.7 metre wide side cantilevers supporting the service pipe bays and footpaths above. The deck is supported on integral reinforced concrete piers on reinforced concrete bases founding on Greensand approximately 2 metres below the Bypass road level. At the abutments the deck is supported on laminated rubber bearings on concrete plinths which are carried by an abutment capping beam and buried concrete columns and bases founding at the same level as that of the pier bases. The 3 continuous spans are 11.5 metres , 17.6 metres and 14.3 metres long making a total length of approximately 44 metres. Expansion joints are provided at each abutment. These are of the buried type consisting of a rubber bridging pad spanning a 30mm gap between top of deck and top of abutment wall with the road surfacing carried continuously over the joint. Painted steel parapets are provided on the outside of the deck which are designed to contain errant vehicles for this class of road. The embankments directly under the bridge are paved with precast concrete open blocks and grass seeded.
