The Utah Department of Transportation has initiated a State Environmental Study (SES) to identify alternatives that would improve traffic flow and safety on US-89 from Farmington north to I-84

Growing traffic demand has caused the US-89 corridor between Farmington and I-84 to become increasingly congested during the morning and evening peak travel periods. Traffic studies project and increase in traffic volume with congestion worsening in the future. The SES will develop and evaluate freeway improvement options to accommodate the growing traffic demand after inviting public input.

The alternatives will include concepts such as constructing an additional lane in each direction and consolidating access points in the study area.

The study will evaluate improvements to the existing roadway that would provide for current and future traffic demands in the region. The alternatives will be evaluated for potential environmental, social and economic impacts. The study results will be used to help UDOT plan transportation needs of the region.

The overall goal of the study is to provide a solution for adding capacity and improving operations and safety on US-89 through Davis County from Farmington to the I-84 Interchange.
