YOLO COUNTY, CA (MPG) – The California Department of Transportation (Caltrans) is alerting motorists of an update to the ramp closures for the ongoing Interstate 80 (I-80) and U.S. Highway 50 (US 50) Pavement Rehabilitation Project in Yolo County.
The Chiles Road on and off-ramps along westbound I-80 will be directly affected by the anticipated weather expected in the area. Since materials related to this repaving work can’t be placed in wet conditions, some current shifts have been cancelled, and the westbound Chiles Road off-ramp closure that was scheduled for this weekend has been postponed until next week.
Caltrans urges motorists to review the new schedule and to plan for additional travel time.
CHILES ROAD CLOSURES:
- The Chiles Road off-ramp (EXIT 78) closure from westbound I-80 has been rescheduled for 9 p.m. Friday, April 4 through 5 a.m. Monday, April 14.
- The Chiles Road on-ramp (County Road 32A) to westbound I-80 closure, which began Wednesday, will remain closed until 5 a.m. Wednesday, April 16.
Westbound Interstate 80 motorists can use Mace Boulevard (EXIT 75) as an alternate entrance and exit for Interstate 80 (see map below).

The work zone is from just west of the Yolo Causeway along I 80 and US 50 in West Sacramento. The speed limit has been reduced to 55 miles per hour 24/7 for the safety of workers and motorists. Work is scheduled to begin as listed but is subject to change due to traffic incidents, weather conditions, availability of equipment and/or materials, and construction-related issues.
The extended lane closures will help to minimize the duration of the work and improve workers’ safety.
This $280 million project includes $47 million from Senate Bill (SB 1), the Road Repair and Accountability Act of 2017. Senate Bill 1 provides $5 billion in transportation funding annually, shared equally between state and local agencies. Road projects progress through construction phases more quickly based on the availability of Senate Bill 1 funds, including projects partially funded by SB 1.

Caltrans District 3 is responsible for maintaining and operating 4,385 lane miles in 11 Sacramento Valley and Northern Sierra counties. Caltrans reminds motorists to “Be Work Zone Alert” and slow in construction zones for the safety of travelers and crews performing these improvements.
