Concrete U-Girder Gaining Traction Outside Colorado

摘要

Ahorizontally curved, precast-concrete, trapezoidal type of box-girder design, created more than a decade ago in Colorado, is gaining traction in Florida and Pennsylvania. Following the successful completion last year of an $85-million interchange in Orlando, where engineers estimated that the girders saved some $9 million, the girders have now been used on an Interstate 95 interchange in Jacksonville and adopted to code by the Pennsylvania Dept. of Transportation.
