Pape-Dawson was responsible for the complex geometric and structural design for this $5M elevated T-Ramp that allows direct, local access to the SH 288 toll lanes centered between existing SH 288 main lanes at Discovery Bay/Hughes Ranch Road in Brazoria County. With tolling operations prohibiting traffic from crossing SH 288 from east to west, we designed traffic control features that forced eastbound traffic to turn left and westbound traffic to turn right at the elevated intersection without blocking southbound turning movements. Replacing costly steel girders, the design team used a cast-in-place concrete span integral with the substructure. We also added carbon fiber wrap to protect the bridge from over-height vehicles. Services also included the design of local street reconstruction, retaining walls, storm sewer conveyance, four signalized intersections, signing, and pavement marking.
