1891 Trail/US Steel/Pennsy+B&O Bridge over Monongahela River at McKeesport, PA

(Bridge Hunter; Historic Bridges; pghbridges; 3D Satellite)

This bridge is also known as the Riverton Bridge, the Union Railroad Bridge and the Mckeesport Connecting Bridge. pghbridges has the date of 1890, whereas Bridge Hunter claims 1891. (Update: Brian G's comment indicates the builders plaque has 1891, so I changed the date in the title.) 

I'm not researching every big railroad bridge I see. For example, I didn't do the Arthur Kill Bridge until I learned it has the longest lift span in the USA. But this truss bridge is special for a couple of reasons. One is that it was converted to a trail bridge in 2007. [Wikipedia] (Bridge Hunter implies it became part of the trail in 2008.) It is part of a trail system that connects Pittsburgh with Washington D.C. The second reason is that it is yet another RR bridge over the Monongahela River that connects two steel making facilities. In this case it connects the US Steel Duquesne Works with its Dorothy blast furnace to the National Tube Works in McKeesport. It also connected the Pennsy on the south (McKeesport) bank with the B&O on the north bank. [pghbridges]

McKeesport Connecting Railroad Bridge


The McKeesport Connecting Railroad Bridge was built in 1890 and once carried Union Railroad trains between US Steel's Duquesne Works and the National Tube Works in McKeesport. It has recently been converted into part of the Steel Valley Trail of the Great Allegheny Passage to Cumberland, Maryland.

The bridge, now part of the trail, provided the rail connection between the National Tube Works at McKeesport and the USS Dorothy Six blast furnace of the Duquesne Works

Union Railroad crossing the McKeesport Transfer Bridge on June 28, 1997. Originally built by the PRR, the Union acquired trackage right over the bridge in 1965 and outright purchased it in 1976. US Steel donated the bridge to the local rails to trails and today you can walk (or bike) over it.
Ian Bowling Steven J Raith do you remember when the last train ran across this bridge? I remember in the early 2000’s that me and my dad saw one going across it at night. That was the last and only time I seen one go across this bridge.
Steven J Raith I want to say around 2006 or 2007? not 100% sure.
Ian Bowling Steven J Raith okay that’s about the time I can remember seeing it. I would’ve loved to catch it in the daytime. Awesome photo!!
[If Steven's dates are correct, then the bridge was converted to trail use within a year or two of the last train running on it.]

InterestingPennsylvania has more photos from and of the bridge. It appears the bridge owners think that it will take rust a long time to reduce the strength of a railroad bridge to be less than that of a trail bridge because the bridge looks rather rusty.

  1. Builder's plaque on the bridge states a construction date of 1891.
