A new precast, prestressed concrete beam was recently developed by the Texas Department of Transportation. Aesthetics and economy were primary design considerations for this open-top trapezoidal beam. Two U-beam bridge projects are currently under contract, with production of the U-beams due to begin in the fall of 1993. This paper discusses the development of the U-beam, including design, production and construction aspects. Cost comparisons with other bridge systems are also given together with anticipated usage of the U-beam.
