Stretch of I-80 to close in Sacramento area for 55 hours. See when and where

Construction will close a key stretch of Interstate 80 for more than two days, according to the California Department of Transporation.

The 55-hour closure will affect access to westbound I-80 from the Interstate 5 interchange to the eastbound Highway 50 interchange in Yolo County, Caltrans said in a news release, as well as various on- and off-ramps in West Sacramento.

Caltrans contractors are working to “complete demolition and pavement work,” the state roads agency said in the release.

Here’s what to know:

What is Interstate 80 construction project?

The Yolo Interstate 80 and Highway 50 Pavement Rehabilitation Project aims to “rehabilitate and repair” the roadway in and around West Sacramento, Caltrans said, to “improve safety and ride quality.”

The construction zone on Interstate 80 stretches from eastbound Highway 50 from the Yolo I-80 ramp to Jefferson Boulevard in West Sacramento.

Which part of I-80 will be closed? When?

Westbound I-80 will be closed from 9 p.m. Friday, Sept. 26, through 4 a.m. Monday, Sept. 29, according to Caltrans.

Here’s which ramps and connectors will be blocked to traffic during that time:

• Northbound I-5 to westbound I-80 connector
• Westbound I-80 to westbound I-80 and Highway 50 connector

These freeway exits off westbound I-80 will also be closed:

• El Centro Road and West El Camino Avenue on-ramps
• Reed Avenue on-ramps
• Enterprise Boulevard on-ramp and off-ramp

“Schedules are subject to change due to weather conditions, availability of equipment or materials,” Caltrans said, as well as “other unexpected events.”

Which detours can I take to avoid roadwork?

Caltrans recommended taking the fpllowing detours to avoid roadwork:

From westbound I-80:

• Take the connector ramp from WB I-80 to SB I-5.
• Continue to southbound I-5

From southbound I-5:

• Continue on I-5
• Take the connector ramp from southbound I-5 to westbound Highway 50
• Continue to westbound Highway 50

For Enterprise Boulevard and West Capitol Avenue:

• Use westbound Harbor Boulevard off-ramp, traveling northbound to West Capitol Avenue
• Use westbound Harbor Boulevard off-ramp to southbound Industrial Boulevard

Caltrans said drivers should slow down in construction zones for “the safety of travelers and crews performing these improvements.”

How much will construction cost? When will it be completed?

The $280 million project includes $47 million in funding from Senate Bill 1, the Road Repair and Accountability Act of 2017, Caltrans said.

SB 1 provides $5 billion in transportation funding annually, shared equally between state and local agencies.

Caltrans estimates that construction will be completed in May 2026.

Tips for driving safely in work zones

Caltrans provided some helpful tips for driving safely in construction zones and avoiding high fine tickets.

Here’s what to know:

• Don’t change lanes unnecessarily.
• Avoid using your phone while driving in work zones.
• Turn on headlights so that workers and other drivers can see you.
• Be especially alert at night while driving in work zones.
• Expect delays, especially during peak travel times.
• Allow ample space between you and the car in front of you.
• Anticipate lane shifts, and merge when directed to do so.
• Watch for workers, and drive with caution.
