Abstract:

The Nebraska Department of Roads is taking advantage of the new high-performance steel (HPS) to develop a modular, two-girder bridge that will employ standardized hybrid HPS components, specifically HPS flanges and conventional steel webs. The new bridge is an attempt to build a uniform structure that can be copied for future short to medium span bridges, as well as structures that will ultimately be updated, so that they will be cost-effective and simple to build. The bridge will feature a box girder cross section, a semicontinuous configuration approach, and a precast, highly durable deck system. It is hoped that these innovations will reduce cost and construction time, and increase the life of the bridge.
