DART narrowing alternatives for eastern end of D2 Subway project
Dallas Area Rapid Transit (DART) continues to evaluate options for the eastern end of the $1.3 billion D2 Subway project as the agency prepares a staff recommendation for October to present to the Dallas City Council.
D2 Subway – East End option
On March 24, 2021, the Council directed the city to work in cooperation with DART, the North Central Texas Council of Governments (NCTCOG), and the Texas Department of Transportation (TxDOT) to define and evaluate potential refinements, enhancements, and modifications within the eastern end of the D2 Subway corridor to address and mitigate technical, environmental, and alignment concerns.
Seventeen alignment alternatives were developed, in three “families”:
- Family 1 – Enhancements/refinements/modifications keep the wye triangular junction in the Swiss/Good Latimer area.
- Family 2 – Moves the wye junction to a new location or underground along Good Latimer.
- Family 3 – Moves the wye junction and alignment to a new location along I-345 and underground.
Of the 17 alternatives, eight will be advanced to the second level screening with the goal of forming a shortlist of two to three alternatives after getting stakeholder feedback.
The overall vision will be based on looking at the D2 Subway, Interstate 345, local street network, and other related infrastructure projects to minimize right-of-way needs and maximize economic development potential.
DART anticipates briefing the Dallas City Council by November followed by drafting an interlocal agreement between the city, DART, NCTCOG, and TxDOT by January 2022. A City Council resolution is scheduled for March 2022.
