I-15 Hamilton Fort

 

Holiday Updates: 

For the Pioneer Day Holiday, Crews will be off the road on Thursday, July 24 through Sunday, July 20. 

 

Project Overview:

The Utah Department of Transportation (UDOT) plans to construct a 13-mile-long northbound climbing lane on I-15 from the Kanarraville rest stop to the South Cedar Interchange, milepost 43 to 56. The project will widen I-15 through this area from two to three northbound lanes. The project will also reconstruct the northbound side of the Hamilton Fort interchange with a roundabout constructed on the east side of I-15 at Exit 51.  

 

Construction is expected to require two construction seasons, beginning in Spring 2025 and ending by December 2026. Construction schedules are subject to change due to weather conditions and material availability.
