I-15 Washington Construction

 

As early as Monday, March 27, the Utah Department of Transportation (UDOT) will begin construction on I-15 between Green Spring Drive (Exit 10) and Washington Parkway (Exit 13) in Washington, Utah. Improvements will include:

  • Widening I-15 to include an additional travel lane in each direction
  • Constructing a new interchange at Main Street (new Exit 11)
  • Implementing intersection improvements at Buena Vista Boulevard and Main Street

This project will improve safety and mobility throughout Washington County by providing additional connections from I-15 to the rapidly growing northeast areas of Washington and the downtown area.
