Preferred Alternative Announced for Future I-35 Interchange at SH-74/Grant Street in Purcell

PURCELL, OK — Following input from the public and stakeholders received earlier this year, the Oklahoma Department of Transportation (ODOT) and City of Purcell announce their preferred alternative for a new I-35 interchange to be constructed at SH-74/Grant Street on the north side of Purcell in McClain County. The project will now move forward to the next phases of development, which include detailed design and environmental review in preparation for future construction.

Alternative 3 adds a full diamond interchange at I-35 and SH-74/Grant Street with both north and southbound I-35 on- and off-ramps. SH-74/Grant Street will be reconstructed with an added center turn lane between Green Avenue and Westbrook Boulevard to help accommodate traffic at the new ramps. Alternative 3 was selected from three design proposals presented for consideration.

During evaluation of the various design concepts and feedback from the public, ODOT and the city found that Alternative 3 best met the performance goals of improved emergency vehicle access, reduced emergency incident response time, improved connectivity to the regional transportation network, and accommodation of continued growth in Purcell.

The estimated $28-million construction project to build the new interchange is scheduled in ODOT’s Eight-Year Construction Work Plan to go to bid in Federal Fiscal Year 2025.
