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


For over 20 years I have had the privilege of working with Keller Engineers and their staff of surveyors, and civil and structural engineers on over $150 million worth of work. During these project relationships and partnering opportunities, my architectural teams have received nothing but premium professional services and courtesy towards my own staff, clients and prospective clients with stellar attention given to building and site details, client responsiveness and peer respect. I look forward to many more teaming opportunities and urge any other architectural firms, municipalities or clients who have not worked with Keller Engineers to do so. You will be pleasantly surprised! Richard L. Karcher, AIA, NCARB
