Project Details

Located on the Lycoming Valley Railroad between Montoursville and Williamsport, this structure replaced an 85-year-old bridge that was heavily damaged by Tropical Storm Lee in September 2011.
The new three-span, 476’ long steel bridge was designed to withstand frequent flooding on Loyalsock Creek by increasing the waterway opening by 50% and supporting the concrete foundation on steel piles driven to bedrock. The three-span configuration was selected to minimize the number of piers within the creek and to permit construction beneath overhead transmission lines at the site. Additional work performed included:

  • 1,700’ of track realignment, construction management and construction inspection
  • rehabilitation of an adjacent 2-span deck girder bridge
  • one at-grade crossing
  • one turn-out
  • various utility relocations


We have worked with Keller Engineers for structural and civil engineering support on six projects over the past five years and have been very pleased with the results. Our projects tend to be complicated phased renovation/ addition projects calling for creativity in planning and construction.  I have been particularity pleased with their responsiveness to issues that arise during construction which is of particular importance to us and our clients.
