Crews will begin assembling a paving machine in the roadway median next week. Paving will start soon in the median near Limonite Avenue.


If you have been driving on the northbound I-15 near the Hidden Valley Parkway off-ramp, chances are you’ve noticed construction of a portable concrete mixing plant or batch plant.

The batch plant will mix the necessary supplies to create the concrete for the 15 Express Lanes. Having the source of the concrete close to the project site will reduce the number of concrete trucks necessary to be on the I-15 and adjacent streets.

The plant is expected to be completed next month, and a conveyor belt will be installed in the fall. The belt will transport the mixed concrete to the I-15 median, reducing the need for cement trucks to travel outside of the construction area.


Check out the latest video on the 15 Express Lanes, featuring information about the project’s soundwalls and the criteria for placing walls at specific locations.




Alternating northbound and southbound I-15 closures are scheduled for the City of Corona’s Cajalco Road Interchange Project later this month.
