Description	In the early 1990's Texas State Highway 249 was upgraded from a four-lane, at-grade road to a limited-access freeway. Consequently, two overpass structures were built at Louetta Road to carry three lanes in each direction, plus shoulders and ramp transitions. The superstructure consists of simple-span pretensioned trapezoidal-shaped 54-inch U-beams as well as precast pretensioned deck panels supported on the U-beams' top flanges with a cast-in-place composite concrete topping. The bridges are three spans each, nominally 130 ft. per span. At the interior bents, each beam is supported by a single post-tensioned pier. All beams and piers were designed and fabricated using high-performance/high-strength concrete.
