The first photo must be of the north end because the bridge is curved and the separate truss in the foreground is going over railroad tracks. The second bridge must be of the south end.

"The current Glenwood Bridge, which opened in 1966, is Pennsylvania's first all-welded, steel truss bridge."
 
"This bridge is unusual because most of the trusses are below deck except at the piers where they rise up forming a through truss design." [HistoricBridges]

To find a railroad tower that is still standing is rare.

Note that long ago, the tower didn't have any graffiti.

It appears to be a former-B&O tower because the upstream railroad bridge is a former-B&O bridge.
