Multiple lanes on the Pomona (60) Freeway will be shut down Monday evening and every night until Friday morning in Jurupa Valley for the ongoing “60 Swarm.”
Beginning at 9 p.m., two of four lanes on the eastbound Pomona Freeway will be taken out of service, and up to four of five lanes on the westbound Pomona Freeway will be closed while crews work on a series of infrastructure improvements that began last summer.
According to Caltrans, the closures on the eastbound side will generally be from Valley Way in Jurupa Valley to the 60/91/215 interchange in downtown Riverside. On the westbound side, the closures will run from Country Village Road in Jurupa Valley to Euclid Avenue in Ontario.
The closures will be lifted at 5 a.m. Tuesday, and another round of shutdowns will repeat Tuesday night to Wednesday morning, Wednesday night to Thursday morning, and Thursday night to Friday morning, during the same hours, according to Caltrans.
The work, which has resulted in traffic backups spanning several miles, even in the middle of the night, is a central part the 60 Swarm.
Altogether, the swarm covers a 20-mile stretch, from Chino to downtown Riverside.
The other part of the Swarm consists of bridge replacements, costing $23 million. According to Caltrans, the Benson Avenue, Monte Vista Avenue and Pipeline Avenue overcrossings in Chino are all set to be razed and replaced with new spans. Alternating eastbound and westbound lane closures for the bridge work started in July.
Most of the overnight lane closures related to the bridge replacements are occurring between Ramona Avenue and Reservoir Street in Chino.
