SEDA-COG Joint Rail Authority, Lycoming County
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.

We have teamed with Keller Engineers on several design-build projects for PennDOT. When selecting a designer, the more critical factors are trust and competence, more so than a low price.
