Possibly the third structure at this location. Circa 1850, the Little Saw Mill Run Railroad built a wooden trestle over West Carson St to connect to its coal docks on the Ohio River. The West Side Belt Railroad, a subsidiary of the Wabash Pittsburgh Terminal Railway, acquired the LSMRR in 1897.
The portion of the WSB east of Banksville Junction (near western portals of the Fort Pitt Tunnels) was built in 1902 and 1903 -- for the most part with wooden trestles and a few plate girder spans. The entire WSB was updated c1909 with longer structures being rebuilt of steel and it is perhaps at this time that the wooden trestle over West Carson St was replaced with a deck plate girder bridge.
The Wabash railroad properties around Pittsburgh were purchased by the Pittsbugh & West Virginia Railroad in 1917.
Allegheny County opened the West End Bridge in 1932. In preparation for the influx of traffic, the West End Circle ramps and bridges were built in 1931. At this time, it appears the present Pittsburgh & West Virginia Railroad bridge was built -- this time as a pony plate girder span, to allow for greater underclearance on West Carson St.
