I-20/I-30 Operational Improvements

The proposed project would include three new interchanges on I-20 and one new interchange on I-30. Portions of the existing frontage roads along I-20 and I-30 would be reconstructed, and shared-use paths for bicycle and pedestrian accommodations would be provided. The project would also include operational improvements to existing cross streets, main lanes, ramps, and auxiliary lanes. The existing facility would be upgraded to meet current TxDOT design criteria. Additionally, the project would evaluate necessary drainage improvements. The first construction phase is anticipated to begin in 2023. Phase 1 would include two proposed interchanges on I-20, frontage road improvements, shared-use paths, and ramps reconfigurations on I-20 and on I-30 from I-20 to Walsh Ranch Parkway. Future construction phases are subject to funding availability.

The proposed project would, subject to final design considerations, require approximately 13.9 acres of additional right of way and would potentially displace one non-residential structure. Phase 1 ROW would be acquired through early acquisition.
