IBC 20-17: Emergency Response and Repair of State Route 6 Bridge over French Creek following Over-Height Vehicle Strike
Frank Artmont, Ph.D., P.E., Modjeski and Masters, Mechanicsburg, PA; Andrew Adams P.E., Modjeski and Masters, Mechanicsburg, PA; Hadi Kenarangi, Ph.D., Modjeski and Masters, Mechanicsburg, PA; Christopher Smith, P.E., Modjeski and Masters, Mechanicsburg, PA; Mark Bredl, P.E., Pennsylvania DOT, Oil City, PA

In January 2019, an over-height vehicle struck a through-truss bridge carrying State Route 6 over French Creek in northwestern Pennsylvania, which caused severe damage to the truss verticals and necessitated the structureā€™s closure. This presentation will highlight the design stage work on the project, including the initial response, finite element analysis, and development of the repair schemes, which enabled the structure to be successfully repaired and reopened in under three months from the accident.

IBC 20-18: Rehabilitation and Widening of the Historic I-78 Mainline Spandrel Arch Bridge

As one of the largest bridge projects in Pennsylvania, the I-78/ SR 61 Interchange Improvement is a multi-phased project currently under design and construction. Rehabilitation and widening of the historic I-78 multiple-span arch bridge over the Schuylkill River is a part of this larger scope. Built in 1955, the existing bridge includes an eight-span, concrete spandrel arch bridge with typical spans of 157.5 ft with an overall length of 1742 ft. The widened spandrel arch bridge will add one lane on each of the existing westbound and eastbound roadways, to a total of six traffic lanes with shoulders.
