Study Overview
The Utah Department of Transportation (UDOT) completed an Environmental Assessment (EA) to evaluate a new interchange at I-15 and Center Street and other improvements to improve safe and efficient access to and across I-15 for all users in central Spanish Fork and surrounding communities by accommodating travel demand in 2050, planned land use, and other planned transportation improvements.
The EA considers current and future transportation needs while taking into account the expected impacts to the natural and built environments.
UDOT identified the Center Street Interchange Alternative as the Selected Alternative and has issued a decision on the EA, which is a Finding of No Significant Impact (FONSI).
Hard copies of the FONSI will be available at the Spanish Fork Library until September 2025.

UTA South Valley Transit Study
While UDOT prepared an EA, the Utah Transit Authority (UTA)l conducted 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 were conducted independently of each other, but both agencies collaborated throughout the study process to inform each agency's respective decision-making process.
