For Immediate Release

Sacramento — The California Department of Transportation (Caltrans) is continuing a series of weekend partial highway closures for the SAC 5 Corridor Enhancement Project this weekend.

This project includes $48.3 million in funding from Senate Bill (SB) 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.

Work on southbound Interstate 5 will temporarily close two lanes in the southbound direction this weekend from Friday night into early Monday morning. Signed detours will be in place, but Caltrans urges motorists to use State Route 99 as an alternate route to navigate around the closure and to plan for additional travel time.


9 p.m. Friday, July 9 through 5 a.m. Monday, July 10.


Southbound SAC I-5 from north of Seamas Ave. to 43rd Ave. (Two lanes will remain open.)


Seamas Ave (Exit 515) On- and Off-ramps closed

43rd Ave. (Exit 514) Off-ramp closed


Use Florin Rd exit (Exit 513) to turn around back onto northbound I-5 to Seamas and 43rd

The around the clock construction work will require heavy equipment and commercial trucking. Nearby residents can expect loud construction type noise and commercial truck back-up beeping noises during day and nighttime hours. The contractor is scheduled to perform paving and striping.

The ongoing work has added sound walls in 2020 and scheduled to rehabilitate 67-lane miles of roadway, will build 23 miles of carpool lanes, and improve the existing electrical and drainage systems along this corridor.

Motorists traveling through the work zone should expect lane restrictions and should be aware of commercial work vehicles traveling in and out of the area. The work zone speed limit has been reduced to 55 mph and the California Highway Patrol will be present for traffic enforcement.

Work is scheduled to begin as listed but subject to change due to traffic incidents, weather, availability of equipment and/ or materials, and construction related issues.
