Loyalsock Creek Railroad Bridge

Owner

SEDA-COG Joint Rail Authority, Lycoming County

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
