The Utah Department of Transportation (UDOT) will widen I-15 from Green Spring Drive (Exit 10) to
Washington Parkway (Exit 13) in Washington, Utah. This project will include constructing an
additional travel lane in each direction as well as creating a new interchange at Main Street (new
Exit 11) in Washington City. The interchange will provide an additional connection from I-15 to the
rapidly growing northeast areas of Washington and the downtown area. Design is in progress and
construction is anticipated to begin in 2023.
