This conveyor belt spans the northbound lanes of I-15 near Hidden Valley Parkway in Norco. The conveyor belt was built to carry concrete from the batch plant, over the roadway, to waiting trucks, which then carry to the concrete to the paving machine. This overhead transfer system eliminates the need for concrete-carrying trucks to cross I-15, requires fewer trucks to supply the paving machine with material, and speeds up the paving process for the 15 Express Lanes Project.


Crews will be placing girders and closing 6th Street at I-15 on Thursday, July 18, from 7 p.m. to 6 a.m. There will be nightly lane reductions from 8 p.m. to 5 a.m. weeknights for demolition work.


The 91 Express Lanes will be closed intermittently from Friday night, July 12 to Tuesday morning, July 16 for toll system upgrades. A complete closure schedule is listed below:
