The Bridge Between Something Old, Something New

This article describes how engineers and contractors are employing new designs and equipment to replace old bridges to make them safer. The author describes situations where heavy rail traffic was stalled when bridges failed due to fire or to a shifting center peer, and how the railroads dealt with it. Railroads are showing more interest in design/build projects which allow a contractor to use more cost-effective techniques and complete jobs within a tighter time frame. Many designs are incorporating precast concrete instead of steel stringers on steel caps to eliminate welding.
