FOR IMMEDIATE RELEASE
Placer County – Caltrans is alerting Interstate 80 (I-80) motorists of full overnight closures of the east- and westbound lanes in the Sierra over the next two weeks for bridge demolition.
I-80 is scheduled to be closed to east- and westbound traffic nightly between 8 p.m. and 8 a.m. Wednesday, May 4 through Thursday, May 5 at Cisco Grove for demolition of the second half of the overcrossing structure. I-80 will also be closed to east- and westbound traffic nightly between 8 p.m. and 8 a.m. Monday, May 9 through Thursday, May 12 at Baxter for full overcrossing demolition.
During the scheduled demolition work, all passenger and commercial vehicles will be detoured off the highway at the off-ramps and back on via the on-ramps. Motorists should expect slight travel delays in the area.
Crews are currently working to demolish and rebuild the east half of the Cisco Grove bridge overcrossing after completing the west half in 2021. An automated one-way traffic control signal will be in use around the clock on the overcrossing through October during construction work.
Further west on I-80, the Baxter Road Overcrossing will be closed to all traffic through August while the structure is rebuilt. Local traffic wishing to access I-80 eastbound should take Baxter Road to the Crystal Springs Overcrossing and use the eastbound on-ramp for I-80.
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 www.rebuildingca.ca.gov.
Project construction began in April 2021 with completion expected in summer 2023. Walsh Construction of Concord is the prime contractor.
Weather or unexpected events may delay or prolong the work. The department will issue construction updates on Twitter @CaltransDist3, on Facebook at CaltransDistrict3 and on the Caltrans District 3 website.
