RAILWAY TRESTLE

PITTSBURGH, PENNSYLVANIA

IMAGE NUMBER 664c

In 1883 the Pittsburgh City Council required the Pittsburgh Junction railway to elevate their railroad on a trestle with 37 spans above 33rd street.  The trestle then leads to the Allegheny River bridge.  The railway is now disused and the tracks have been removed, but the trestles remain.  Interestingly, Uber's Pittsburgh technology centre is located on the Allegheny River adjacent to the trestles - Uber's driverless cars circulate beneath the trestles to and from the Uber facililty.  While taking these images, security staff from Uber insisted (unsucessfully) that Atticus should delete his images.
