Placer County – Caltrans is alerting Interstate 80 (I-80) motorists to expect continued intermittent off- and on-ramp closures at Baxter and Cisco Grove through October for construction improvements.  

A newly reconstructed overcrossing on Interstate 80 in Placer County features mountain reliefs on the side, improved lighting and decorative wire fencing.Grinding and paving work is expected to continue through the end of the month on the I-80 Baxter off- and on-ramps. Ramps may be closed intermittently with motorists directed to use Crystal Springs (Exit 148A) for access to local roads. In addition, final polyester concrete overlay work on the new Baxter Overcrossing is scheduled October 31 and November 1. The structure will open to traffic following completion of this work.

At Cisco Grove, motorists should expect full daytime closures of all off- and on-ramps between 7 a.m. and 7 p.m. Wednesday, October 19 through Friday, October 21 for grinding and paving work. The full ramp closures will expedite construction work, but intermittent ramp closures may still be required through Monday, October 24.

The automated one-way traffic control signal on the Cisco Grove Overcrossing is also scheduled to be removed on Tuesday, October 18, permitting traffic flow in both directions across the rebuilt structure.

The construction schedule is subject to change based on weather, availability of materials or equipment, or other unexpected events.

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. For more information about other transportation projects funded by SB 1, visit Rebuilding California.

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