The study also considered potential impacts to the local street grid and existing transportation infrastructure; current and future development plans, including Dallas Area Rapid Transit's (DART) D2 Subway Line; environmental impacts; and stakeholders' input. TxDOT conducted three series of public meetings between December 2019 and May 2022 to gather feedback and share preliminary information about the project.
TxDOT has identified a recommended alternative, known as the "Refined Hybrid Option," that reconfigures the design of IH-345 to put the interstate main lanes in a below grade/ trench configuration and provides existing and new city street connections above the interstate, including pedestrian and bicycle facilities.
