New Highway Spurs Advanced Bridge Construction Technologies

Pennsylvania roadway bridges are not just designed to bear traffic, they must handle the extreme temperature fluctuations of the winter and summer cycles. Recent construction of Interstate 99, in central Pennsylvania, has provided an ideal arena for examining two popular bridge types that are the subject of separate studies by Pennsylvania State University.

Field Monitoring of Integral Abutment Bridges - As the success of integral abutment bridges (IABs) has led to increasingly longer spans, uncertainties in predicting the long- and short-term performance of these bridges and related design principles has warranted real-world validation.
