Louetta Road Overpass—Lessons Learned

Open publisher page 0 citations

Abstract

This paper describes how the Louetta Road Overpass near Houston, Texas, is one of the first projects in the Federal Highway Administration (FHWA) national high performance concrete (HPC) bridge implementation program. The overpass, which consists of two parallel bridges, utilizes precast, prestressed and cast-in-place HPC in both the superstructure and substructure. This paper describes this overpass and discusses how the use of high strength concrete allows for longer span bridges.
