"It moves us another step closer to completion of the Albion Park Rail bypass," Mr Ward said, "which will deliver the final link in an upgraded road between Sydney and Bomaderry, bypassing 16 intersections and wiping 30 per cent off travel times through the area."
Of the 13 bridges being built there are five waterway crossings, one access crossing, one railway crossing, three road crossings and three bridges being built as exit/entry ramps to the motorway.
The bridge is made up of 10 Super-T girders, each of which is 1.5-metres deep and weigh more than 60 tonnes.
