Interstate Exit Number Changes Almost Completed

Mileage markers have now been updated along Utah freeways and highways and some Interstate exit numbers are being changed to make them consistent with the new numbering system. This website has specific information.

Utah’s highways were built over many decades. In a few places inaccuracies and inconsistencies were introduced, which are now being corrected. Most changes are on I-15 from Nephi north. Initial plans called for the freeway to be routed through town, and numbers were calculated accordingly, but the interstate was actually routed around the community.

The entire project will be completed during the next couple months.

Travelers need to be aware that maps and guidebooks keying on mile markers and/or exit numbers may no longer be accurate. Check with local businesses for accurate information about their areas.
