For Immediate Release

Placer County – Caltrans is alerting Interstate 80 (I-80) motorists of full closures of the east- and westbound lanes at Cisco Grove this week for bridge girder installation.

I-80 is scheduled to be closed to east- and westbound traffic nightly between 9 p.m. and 8 a.m. Wednesday, July 28 through Thursday, July 29 at Cisco Grove. All passenger and commercial vehicles will be detoured off the highway at the off-ramps and back on via the on-ramps during construction work. Motorists should expect slight travel delays in the area.

Crews are currently working to reconstruct the bridge overcrossing at Cisco Grove. Work this week will include the installation of pre-cast girders that will form the roadway base for the new overcrossing. Around the clock one-way traffic control is currently in effect on the overcrossing during construction work.

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 RebuildingCA.

Project construction began in April with intermittent lane closures and local detours occurring during the day and at night. Walsh Construction of Concord is the prime contractor. Project completion is expected in summer 2023.

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.
