Dallas Streetcar, Union Station to Oak Cliff
In December 2010, the Federal Transit Administration (FTA) awarded a $23 million TIGER grant to support a proposed transit project to provide a streetcar from downtown Dallas to Oak Cliff. This project has been a collaborative effort between the City of Dallas, North Central Texas Council of Governments (NCTCOG), Dallas Area Rapid Transit (DART) and the FTA. After the grant was awarded, the project was further defined to consist of an approximate 1.6-mile streetcar route extending from near Union Station in downtown Dallas to the Methodist Dallas Medical Center in Oak Cliff.
DART selected the Stacy Witbeck/Carcon Joint Venture team with HDR as its lead designer for the Dallas Streetcar Oak Cliff Line, which will be the first modern streetcar in Dallas. We began working on this project in 2012 during the proposal phase when the design team, working with the contractor, refined the preliminary engineering design and developed several cost-saving innovations. We phased final design to sequence with construction and issued four design packages from February to December 2013. This allowed construction to begin on the Houston Street Viaduct and long-lead item procurement to begin in March 2013, enabling project construction to move forward as design was incrementally completed.
The Dallas Streetcar is a unique and challenging project, involving rehabilitation of a 100-year-old structure (Houston Street Viaduct), operating bi-directionally on a single track, connection to and operating non-revenue service on the adjacent light rail tracks and is the first modern streetcar or light rail transit project in the United States to have a substantial off-wire segment (approximately one mile with no overhead wires).
The 1.6-mile Dallas Streetcar starter line opened to revenue service on April 13, 2015.
Our success on the initial project resulted in DART retaining our team to provide design for the two planned extensions to the project. The south extension consists of approximately 0.7 miles of double track — extending the line to the Bishop Arts District, an area the city is focusing on revitalizing. This streetcar extension is seen as a key component to the success of the arts district. The north extension is currently under evaluation and is intended to better serve the convention center in downtown Dallas. Through this contract, our team will provide final design and construction support for both extensions.
