1904 AVR/Pennsy Brilliant Branch Cutoff Bridge over Allegheny River and UY Tower

Tower: (Satellite, not only is the tower gone, but so is the track on the eastern connection.)

The Water & Sewer Authority land used to have an elegant power plant. A different power plant was standing there in this Flickr Photo.

The Brilliant Branch Railroad Bridge was constructed for the Brilliant Branch of the Pennsylvania Railroad (PRR) and featured a 1,200-foot-long Warren truss bridge across the Allegheny River between Pittsburgh and Aspinwall, Pennsylvania.
The Brilliant Branch, also referred to as the Brilliant Cut-Off, was constructed by the PRR as a cut-off to avoid the busy Union Station and its yards downtown and as the final component of a railroad beltway around Pittsburgh. The bridge opened to traffic in 1904.
In the wake of the collapse of Penn Central (PRR’s successor) and in the midst of the U.S. Railway Association’s controversial $7.3 billion railroad revitalization plan, it was proposed to reroute 25 to 35 through freight trains from the Fort Wayne Bridge in downtown to the Brilliant Branch river crossing. But it was feared that it would cause congestion because of the steeper grades and sharper curves at the wye in Aspinwall. Instead, the Brilliant Branch was abandoned, only to be revived in 1995 for the Allegheny Valley Railroad (AVRR).
The line has only been minimally used since 2019 after the loss of AVRR's only customer north of the Allegheny River crossing.

There were 10-15 locomotives in this "light engine" move across PC's ex-PRR Brilliant Bridge, probably bound for Conway Yard some 30 miles west. That's UY tower just visible at the end of the bridge. 1975.

Ivan's photo not only clearly shows the cut-stone construction of the piers, he documents that there was a junction tower in the wye on the west side. So once again, I fire up the wayback machine to find the location of the tower.

It is off the eastern connection soon after it forks off the bridge.
