The Adam Viaduct is a grade II listed concrete underbridge in Wallgate, Wigan. The bridge, constructed in 1946, is the earliest 'post-tensioned' prestressed concrete railway bridge in the United Kingdom, with only some examples in Switzerland being earlier.[1][2] It is bridge number 54 on the Kirkby branch line and is at a line distance of 18 miles 1,032 yards (29.91 km).[3]
