by Sacramento, CA – Motorists traveling along Interstate 80 (I-80) between Natomas and West Sacramento should prepare for significant closures throughout September 2025, as Caltrans undertakes a major pavement rehabilitation project. The work is part of the agency’s ongoing $280 million effort to improve the safety and longevity of both I-80 and Highway 50.
Weekend Closures to Begin September 4
The first major closure will begin Thursday, September 4 at 9 p.m. and continue until Monday, September 8 at 4 a.m. This 55-hour weekend closure will affect westbound I-80 traffic from the Interstate 5 interchange in Natomas to the Highway 50 and westbound I-80 interchange.
During this period, Caltrans will close several ramps and connectors, including:
- Northbound I-5 to westbound I-80 connector
- Westbound I-80 to westbound I-80 and US 50 connector
- West El Camino on-ramps to westbound I-80
- Reed Avenue on-ramp to westbound I-80
Additionally, the westbound I-80 connector to eastbound Highway 50 will be closed 24 hours a day through September 18, requiring careful planning for commuters.
Nightly Closures After September 8
According to CBS News, Following the weekend shutdown, Caltrans will implement nightly closures from September 8 through September 18 along the same stretch of I-80.
- Weeknight closures: 9 p.m. to 3 a.m.
- Weekend closures: 11 a.m. to 5 p.m.
These closures are designed to allow crews to complete pavement repairs while minimizing disruption during peak daytime hours.
Detours and Travel Advice
Motorists are strongly encouraged to plan alternate routes to avoid delays. Caltrans recommends the following detours for westbound I-80 traffic:
- Take the connector ramp to southbound I-5, then exit onto westbound Highway 50, which reconnects to westbound I-80 over the Yolo Causeway.
- Travelers from West Sacramento can access westbound I-80 via the West El Camino on-ramp or the Harbor Boulevard on-ramp, which links to westbound Highway 50.
For those heading toward the Bay Area, Caltrans advises considering southbound I-5 or southbound Highway 99 as alternative routes to bypass congestion.
Project Scope and Goals
The ongoing I-80 and Highway 50 rehabilitation project focuses on repairing damaged pavement, improving roadway safety, and extending the lifespan of the freeway infrastructure.
According to Caltrans officials, the work will include:
- Resurfacing worn asphalt sections
- Reconstructing damaged lanes
- Upgrading ramps and connectors for smoother traffic flow
The agency emphasizes that these improvements, while causing temporary inconvenience, are crucial for reducing future maintenance disruptions and ensuring safer travel for thousands of daily commuters.
Tips for Commuters During Closures
Motorists are advised to:
- Check traffic updates daily via Caltrans’ QuickMap or local news outlets.
- Allow extra travel time when planning trips across the affected area.
- Use public transportation or telecommute if possible during peak closure periods.
- Follow all posted detour signs and traffic control measures to ensure safety.
Commuters are reminded that violating lane closures or construction zones can result in fines and penalties, and endanger both drivers and construction crews.
Community Impact
The closures are expected to cause significant delays for residents and commuters in Natomas, West Sacramento, and surrounding areas. Businesses along the corridor are advised to plan deliveries and staff schedules around the closures.
While temporary delays are anticipated, Caltrans reassures the public that the work will result in safer, more durable highways and improved connectivity across the Sacramento region.
