D2 Subway


  • DART and the FTA completed the Supplemental Draft Environmental Impact Statement in May.

  • The agency has finished preliminary engineering design to the 20% level and will reach 30% by year end.

  • DART is working with TxDOT to integrate the D2 Subway design with plans for I-345.


DART is seeking to finish the project development phase of the D2 Subway project, also known as the Dallas Central Business District (CBD) Second Light Rail Alignment.

In partnership with the Federal Transit Administration (FTA), the agency completed the Supplemental Draft Environmental Impact Statement (SDEIS) in May. The SDEIS contains several appendices, including 20% Preliminary Engineering design plans. A 45-day public comment period for the SDEIS ran from May 15 to June 29.

DART also is meeting regularly with the Texas Department of Transportation, the North Central Texas Council of Governments and the city of Dallas regarding the D2 Subway interface with Interstate 345. TxDOT is conducting a two-year feasibility study of options to rebuild or remove the elevated highway. DART plans to locate D2's east tunnel portal under the elevated I-345. To date, TxDOT options include D2 Subway as currently designed.

The agency is working closely with FTA to advance the project into the engineering phase of the Capital Investment Grant program to support a future grant. DART will also monitor other stimulus programs that could be announced in the future.

By the end of the 2020, DART plans to complete the 30% design level and work with FTA to issue a combined Final Environmental Impact Statement and Record of Decision. These project milestones will ensure that the D2 Subway is ready to move forward at the appropriate time.

FTA awarded DART $1 million to plan for transit-oriented development at the five D2 Subway stations. DART is coordinating with the city of Dallas and will engage key stakeholders around the stations. The effort will support an implementation plan that outlines potential zoning changes and defines multimodal accessibility improvements.
