UDOT is hosting a public hearing to present the findings of the I-15 environmental reevaluation, provide
an opportunity to submit written or verbal comments, display the preliminary design of the project, and
answer questions from the public.
When: Wednesday, June 25, 2025, from 5 – 7 p.m.
Where: Dixie Middle School (929 S 100 E, St. George, Utah 84770)
The reevaluation of the I-15 South EA and the I-15 St. George Improved EA is being completed to include
the addition of the new overpasses and local connections at 400 East and 900 South that were not part of
the original studies.
A new I-15 interchange at 700 South will not be constructed as part of this project. The project will:
• Widen I-15 from two to three lanes between Bluff Street (Exit 6) and St. George Blvd. (Exit 8)
• Replace structures and raise I-15 at 100 South and 700 South
• Construct new structures over 400 East and 900 South to establish local street connections under
I-15
• Coordinate the realignment of several utilities and the installation of new utilities
• Improve various drainage facilities along and under I-15
The reevaluation process began in fall 2024 and is scheduled for completion by summer 2025, with
construction of the project planned to begin in summer 2026. Environmental documents are process-
driven, so the schedule is approximate and subject to change.
A public comment period for the reevaluation is open from June 18 through July 7, 2025.
