Construction of 532’ long four span continuous prestressed concrete I-beam bridge with a 39 curb-to-curb width.
The project involved the design of a new structure carrying new southbound lanes of S.R. 6015 over the Tioga River. The project is part of the enhancement of S.R. 6015 to a 4-lane limited access highway that will eventually become a part of the Interstate 99 corridor. This structure was built adjacent to an existing companion structure. Traffic was maintained on the companion structure during construction. The structure is founded on steel H-pile supported concrete abutments and piers. The piles extended up to 75 feet to bedrock through clay and gravel. The piers are a combination of multi-column bents atop a solid shaft. The structure was designed for load and resistance factor design (LRFD) criteria utilizing STAAD computer program structural analysis and design software in conjunction with Pennsylvania Department of Transportation (PennDOT) design programs and manual computations.
Larson Design Group performed complete structural design, drafting, and construction consultation for this project.
