The Medical District Drive project improves traffic and pedestrian access to Dallas’ Medical District area by expanding the section of the roadway between Southwestern Medical Avenue and IH 35E in Dallas. The federally funded, Complete Streets expansion entails six through lanes, turning lanes, bike lanes and 6’-8’ wide sidewalks. Other improvements include eliminating the sub-standard vertical clearance by phase-constructing the steel thru-plate girder Trinity Railway Express (TRE) Bridges (complex structures) and alleviating flooding in the area. This street serves as the main entrance to the newly renovated Children’s Medical Center of Dallas and provides a conduit for both vehicular and pedestrian traffic. Pedestrian traffic to the area is generated from the new DART Light Rail Station east of Harry Hines at the current TRE commuter rail station, which is located north of the TRE Bridge over Medical District Drive. The project improves traffic and pedestrian access to the area by expanding the section of the roadway between Southwestern Medical Avenue and IH 35E. Financing for the project included Federal STP-MM funds and Federal Congressional Demo funds administered by TxDOT, Dallas County and City of Dallas. The City of Dallas designated Dallas County as a project lead and this Dallas County project included many stakeholders including FHWA, TxDOT, North Texas Council of Government, City of Dallas, Dallas Water Utilities, Trinity Railway Express, Dallas Area Rapid Transit, Herzog, Southwestern Medical District, Texas Trees Foundation, Children’s Medical Center, UT Southwestern Medical Center, Parkland, Trinity Strand Trail, Oncor, ATMOS, AT&T, Time Warner/Spectrum and the contractor, Structural Assurance LLC.
