A little history: The railroad bridge that was there was part of the Pennsylvania Railroad’s Washington Avenue Branch that came off the Northeast Corridor and ran down the middle of Washington Avenue. Right in the east side of the bridge was a large slaughterhouse. On old railroad maps it’s shown as an “abattoir”. The last business to occupy the building was the Penn Packing Company, which ceased operations sometime in the 1970s. IIRC, it processed chickens.

I’m old enough to remember seeing trains on Washington Avenue. My mom used to talk about having to wait for trains to pass so she could cross the street.
