The Philip J. Fahy Memorial Bridge, or the New Street Bridge, is a 1,500- linear-foot steel truss bridge that spans the Lehigh River in Bethlehem, Pa.

 Currently, the bridge contains four vehicular traffic lanes, divided by a concrete median and a deteriorating pedestrian walkway, which was closed to the public in 2011.  

 While there are many technologies and services used to acquire critical data associated with railways and their rights-of-ways, some can be cumbersome and require logistical challenges that can increase risk to track workers.
