As early as Sept. 6, crews are scheduled to reduce southbound I-15 to three lanes at the Orem Center Street interchange. Southbound I-15 is already reduced to three lanes at the 1600 North and 800 North interchanges. Auxiliary lanes connecting the on- and off-ramps will be provided to allow drivers the opportunity to enter and exit I-15 safely. This restriction allows crews to finish preparations for the dividing of the southbound lanes of the freeway toward the end of September.
