Summary

Description
English: Adam Viaduct Adam Viaduct (built in 1946) near Wigan replaced the original (1848) Lancashire & Yorkshire bridge and carries the Wigan to Kirkby railway over the River Douglas. This is the first example in this country of a prestressed concrete viaduct carrying a railway. It has 4 spans of about 29' each, with 16 I-beams in each span. It was prestressed with the Freyssinet system. The advantages were claimed to be the speed of erection; ballasted track could be used and the heavier beams meant that the bridge was less lively. This bridge is still in use and has recently (1999) been listed by English Heritage.
