A little history from "Bean's 1884 History of Montgomery Co, PA" about the Gwynedd Tunnel that the bridge is built over.

...the North Pennsylvania Railroad, which was opened for travel to Gwynedd Station June 19, 1856. Nearly a mile above this is the Gwynedd tunnel, five hundred feet in length, and, including the cut, three thousand six hundred feet, its greatest depth being sixty feet. It was made through the hardest rock, involving considerable labor and expense, and it retarded for awhile the progress of the road, which was opened through to the Lehigh River January 1, 1857. It has a course through the township of about six miles, with stations at Penllyn and Gwynedd.
