A UDOT Study

Purpose and Need

Growing traffic demand has caused the US-89 corridor between Farmington and I-84 to become increasingly congested. By 2040, traffic volume will increase by 35%, from 37,700 to 50,800 vehicles per day. This will exceed the current capacity of US-89.
More Info

Under the No-Action scenario, peak commute times will increase from about 11 minutes to upwards of 50 minutes between Main Street and I-84. In addition, more than 400 crashes have occurred in the last 3 years, 10 resulting in serious injury or fatality.
