I-15 Washington Construction

The Utah Department of Transportation (UDOT) has started 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. Drivers should expect additional traffic impacts and delays throughout construction. For the latest information on traffic patterns and restrictions during construction, visit the UDOT Traffic website or download the UDOT Traffic app for iPhone or Android. Construction will continue through summer 2024. Construction schedules are weather-dependent and subject to change.
