Value Engineering Arbor Road Bridge with Curved Precast Concrete Girders

The Arbor Road Bridge is an Interstate-80 overpass in Lincoln, Nebraska, consisting of 2 spans that are approximately 142 and 136 feet long, respectively. It is a horizontally curved bridge with a skew of 31 deg. The original design used Grade-50 weathering steel plate girders and haunched segments spliced over the pier. Due to the high cost of steel girders at the time the project was bid, a value engineering proposal using a precast concrete alternative was approved by the owner. This paper describes a number of innovative designs used in this project, including curved precast concrete girders and precast concrete deck panels. Also presented are the girder analysis and design procedures, a description of the production of the precast concrete girders and deck panels, the construction sequence, and a cost comparison between the concrete and steel alternatives.
