SACRAMENTO – Caltrans is continuing a series of Extended Weekend partial highway closures on Interstate 5 for the SAC 5 Corridor Enhancement Project in September.

The weekend construction work involves closing two lanes for northbound and southbound directions from Friday night through early Monday morning.

Caltrans urges motorists traveling along I-5 to expect delays and plan for additional travel time. Caltrans suggests using State Route 99 as an alternative.

The around the clock construction work will require heavy equipment and commercial trucking. A contractor is scheduled for removal of PCC pavement, roadway excavation, placing aggregate base, HMA paving, and striping work.

Nearby residents can expect loud jack hammer type and commercial truck back-up beeping noises during day and nighttime hours.


From 9 p.m. Friday, September 18 through 5 a.m. Monday, September 21.


Northbound SAC I-5, work will be on the inside two lanes at the following locations:

  • 35th Avenue (Postmile 19.1)
  • Seamas Avenue(Postmile 19.3)
  • 25th Avenue (Postmile 19.9)

The #1 & #2 lanes will be closed from South of 43rd Avenue to North of 25th Avenue. Two lanes will remain open and no ramp closure.

Southbound SAC I-5, the work will be on the inside two lanes at the following locations:

  • North of Lincoln Hwy(Postmile 23.5)
  • Under Route 50(Postmile 22.5)
  • Broadway Blvd(Postmile 22.3)
  • Sutterville Rd(Postmile 20.5)

The #1 & #2 lanes will be closed from North of the West End of Viaduct to South of Sutterville Rd. Two lanes will remain open.

Construction work includes removing PCC pavement, roadway excavation, placing aggregate base, HMA paving, and striping.


  • None 

The ongoing work is part of a $370 million project to rehabilitate 67 lane miles of roadway and build 23 miles of carpool lanes, add additional sound walls and improve the existing electrical and drainage systems.

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. For more information on this project text 'FixSac5' to 81257 or visit FixSac5Caltrans encourages the public to follow construction updates on Twitter and Facebook @FixSac5.
