Asking for location research purposes. Can't find a height on Google. Doesn't have to be specific, just need a benchmark figure. Thanks in advance!

Thank you soo much! Exactly what I wanted to know. Sounds like you know a lot more about bridges than I do!

I thought this was a simple enough question, but PennDOT's GIS site only has deck area, lanes, and length, but no clearance or height information. Weird. I'm glad the other commenter thought of using the topo maps.

I thought it was odd as well! No official info to be found on my part.

He's a more detailed topo map using 5' intervals. The northern approach is at 950', and the old ravine floor where saline street used to be is approximately 830'. So the 120' height above ground holds, but not sure how much that changed when the parkway was build. Probably not more than a couple feet, which is within the margin of error anyhow due to 5' intervals. Doubt penndot did much more than grading.

Based on Topographic Maps, and counting 20' interval contour lines - looks like its about 100 to 120' high from I-376 to the crest of the valley.
