The I-15/Cajalco Road Interchange Improvement Project features the reconstruction of the interchange located on Interstate 15 (I-15) at Cajalco Road from Temescal Canyon Road to Bedford Canyon Road. The $45 million-dollar investment includes the widening of Cajalco Road from a two-lane bridge to a six-lane overcrossing bridge with a new alignment north of the bridge. In addition, the bridge will include a striped median, outside shoulders and a sidewalk on the southern side.

“It is an exciting day in Corona to see this important phase of the project come to completion,” said Public Works Director, Nelson Nelson. “The improvements will increase the capacity of the bridge and ramps in order to reduce congestion and accommodate projected growth in the area. We look forward to the completion of the entire road system estimated for Fall 2019.  The landscaping and hardscaping will be completed shortly afterwards.”
