Environmental Assessment Public Comments Closed

The public comment period for the I-15 Spanish Fork Interchange Study Environmental Assessment (EA) is now closed. Thank you to all the community members who submitted comments. We are currently reviewing all comments to see if changes to the EA are necessary and will provide responses in the decision document, which is expected to be published in Spring 2025.

There is currently no funding for final design or construction, so construction timing is unknown.

Preferred Alternative: Center Street Interchange

UTA South Valley Transit Study

While UDOT prepares an EA, the Utah Transit Authority (UTA) will conduct the South Utah Valley Transit Study to evaluate options for expanding FrontRunner transit service in the southern portion of Utah County, which includes Spanish Fork.

The UDOT study and the UTA study are being conducted independently of each other, but both agencies will be collaborating throughout the study process to inform each agency's respective decision-making process.
