Multiple lanes and a heavily used connector ramp on the westbound Pomona (60) Freeway between Eastvale and Ontario will be shut down this weekend and on successive weekends as part of the "60 Swarm" resurfacing and bridge replacement project.
Beginning at 10 p.m. Friday and continuing until 5 a.m. Monday, two of five lanes on the westbound 60 will be taken out of service between Interstate 15 and Archibald Avenue, a roughly two-mile stretch, according to Caltrans.
Spokeswoman Terri Kasinga said the closures are necessary to enable crews to expedite pavement replacement work.
The westbound HOV and No. 1 lanes will remain available during the 55hour closure, which will also require partially shutting down the I-15/60 Freeway Interchange in Eastvale.
The northbound I-15 connector to westbound 60 will be closed, with detours will be in place, according to Caltrans.
The same closures are scheduled again on the weekends of Sept. 26-27, Oct. 3-4, Oct. 10-11, Oct. 17-18 and Oct. 23-24.
The 60 Swarm got underway in July 2019, and since then, lane shutdowns have been a regular occurrence from Chino to the 60/91/215 interchange in downtown Riverside.

According to Caltrans, two of five lanes on the eastbound side of the freeway continue to be closed nightly, Monday to Friday, between Valley Way in Jurupa Valley and the 60/91/215.
Freeway entrance and exit ramps in the construction zone are being intermittently closed during the overnight hours, as well.
The work, which has resulted in traffic backups spanning several miles, even in the middle of the night, is a central part of the 60 Swarm, which altogether covers a 20-mile space.
The other part of the project is comprised of bridge replacements, costing $23 million. The Benson Avenue, Monte Vista Avenue and Pipeline Avenue overcrossings in Chino are being replaced with new spans. Alternating east- and westbound lane closures for the bridge work started over a year ago.
Most of the overnight lane closures related to the bridge replacements are occurring between Ramona Avenue and Reservoir Street in Chino.
