Susquehanna River Bridge Replacement

Rendering of new Susquehanna River Bridge

Jay Rohleder of Figg Bridge Engineers spoke to almost 50 ABCD / ASCE members on the design of the Pennsylvania Turnpike’s new Susquehanna River Bridge on Nov 18, 2004 . The 150 feet spans will total 5900 feet for the main river crossing and this bridge will be Pennsylvania ’s first segmental prestressed concrete construction project. The 1279 segments will weigh up to 175 kips each. The 6000 psi segments will be constructed using the truss launch method and can be erected at a rate of 2 spans per week. Preliminary load tests were conducted for the substructure units and contributed to a significant cost savings. Drilled Shafts with 6 foot diameters will be used. The drilled shafts would have been designed more conservatively and larger without this testing. The team of Kraemer / Wagman is the winning contractor and will construct the dual 3 lane structures for $82.4 million.

Mr. Rohleder directed his honorarium to Habitat for Humanity and the Boy Scouts of America.
