I-15 and 700 South Environmental Assessment in St. George

Public encouraged to provide input during a formal 30-day public comment period.

UDOT is seeking public input on a potential new interchange at I-15 and 700 South to improve regional mobility in the St. George area. The public is invited to attend a public scoping meeting to share feedback about their transportation needs in this area, ask questions, and learn more about the process and timeline.

Both an online and in-person format will be available, with the same information presented at both meetings. Materials will be posted on the study website following the meetings.

  • Online Meeting: May 3 from 6 – 7 p.m. held via Zoom. Attendees should register in advance on the study website: udot.utah.gov/go/I15StGeorge.
  • In-Person Open House: May 4 from 4 – 6 p.m. at Atwood Innovation Plaza at DSU, 453 South 600 East in St. George.

UDOT is preparing an Environmental Assessment, according to the National Environmental Policy Act, to determine the need for a new interchange on I-15 and 700 South; evaluate potential interchange alternatives; and identify any corresponding impacts.

A public comment period is open from April 18 through May 17. The input provided to the team will help them understand the transportation needs and develop interchange alternatives. Comments can be submitted in person at the scoping meetings, online on the study website, emailed to i15stgeorge@utah.gov, or mailed to I-15 Study Team, 6605 S. Redwood Road, #200, Salt Lake City, UT, 84123. A public hearing is planned for fall 2022. The study is anticipated to be completed in winter 2022/23.
