This report describes the construction of an integral bridge on the M1-A1 Link Road. The bridge deck has two spans totalling approximately 50m and comprises prestressed concrete beams composite with a 200mm thick reinforced concrete slab. The deck is structurally connected to full height reinforced concrete abutments. Field instrumentation and measurements during construction are described together with seasonal effects arising from thermal expansion of the deck during its first three years in service. The findings are relevant to further updating of BA42 (DMRB 1.3) on the design of integral bridges. (A)
