This bridge was definitely never used by the Reading, it was on the PRR's Schuylkill Division as a crossing of the Reading's Philadelphia-Pottsville mainline.
Forgot to mention by doing this your car will not be towed.
As mentioned in the Reading Eagle on 8-26-16 this is a warning to anyone parking to see this bridge on the trail.Make sure to park away from the Kernsville Dam which is posted with no trespassing signs because of people swimming around the dam.
The railroad categories are for both the roads on and below the bridge.
