About the I-15 Express Lanes Project

The 15 Express Lanes project will add two tolled express lanes in each direction on I-15 between Cajalco Road and SR-60, a distance of approximately 15 miles. Drivers will be able to enter and exit the tolled facility at multiple locations, and the project continues RCTC's ongoing commitment to expand the express lanes network. Construction in the median began in March 2018. The new lanes are expected to open in 2020. For more information visit the project webpage at

Due to the dynamic nature of construction, this information is subject to change.  If information is needed in another language, please contact RCTC at (951) 787-7141 for free translation services.
