Railroad Construction is more than just railroadsTaking that out of context slightly...in general, that is quite true, especially historically speaking. The New York Central RR built the Miller Elevated Highway in Manhattan (now demolished due to deferred maintenance), the Erie Railroad built the I-87 overpass in Suffern, and most of the Pennsylvania Turnpike (I-76) was built by the South Pennsylvania Railroad.

It shares common piers with the Pennsy's Harsimus Branch bridge, which was designed and built by PRR enginering staff. Both structures were built concurrently, with the PRR bridge opening one day before the Wittpenn Bridge.
I am assuming that the Penn. RR did not build the Wittpenn Bridge out of generosity. The State probably financed it.
