PLACER COUNTY – Caltrans is alerting Interstate 80 (I-80) motorists to expect continued intermittent overnight closures for bridge reconstruction work in Placer County this week.

Beginning at 8 p.m. Friday, westbound I-80 will be reduced to one lane from Drum Forebay to Crystal Springs. A full closure of westbound I-80 is scheduled to go in effect from 10 p.m. Friday until 7 a.m. Saturday. All passenger and commercial vehicles will be detoured off the interstate at the off-ramps and back on via the on-ramps during the closure. Construction crews will be running cables through newly installed Baxter overcrossing bridge girders to ensure proper alignment and structural integrity.

After the Labor Day holiday, I-80 motorists may also expect intermittent overnight interstate closures near Cisco Grove and Baxter for continued bridge work. Mainline I-80 may be closed intermittently at night during concrete work on the overhead structures. The same ramp detours will be utilized throughout September with minor travel delays expected.

The work is part of a $57 million project to replace four I-80 bridge overcrossings in Placer County: Crystal Springs, Baxter, Drum Forebay and Cisco Grove. The structures are being demolished and rebuilt due to cracking and spalling of the concrete decks and high corrosive chloride content in the deck surfaces. All overcrossings are being widened to include 8-foot shoulders, 6-foot sidewalks and will include ramps that comply with Americans with Disabilities Act (ADA) standards.

The project includes $3.48 million in funding from Senate Bill 1, the Road Repair and Accountability Act of 2017. SB 1 provides $5 billion in transportation funding annually split between the state and local agencies. Road projects progress through construction phases more quickly based on the availability of SB 1 funds, including projects that are partially funded by SB 1.

Project construction began in April 2021 with completion expected in summer 2023. Walsh Construction of Concord is the prime contractor.
