I-15 The Point – Single Point Urban Interchange Upgrade
The I-15 The Point project rebuilt the interchange at 14600 South, replacing the former diamond layout with a modern Single Point Urban Interchange (SPUI). This fast-track design-build effort widens the corridor and keeps traffic moving between Salt Lake and Utah Counties. CMT Technical Services
Why the Upgrade Matters
By converting the junction to a SPUI with three lanes in each direction, the project eases peak-hour congestion and shortens travel times along one of Utah’s busiest stretches of I-15. State reports show the new layout relocated frontage roads and expanded capacity through the Point of the Mountain growth area.
