Northbound I-5 in north Los Angeles County will be reduced to three lanes from two miles south of Vista Del Lago Road to two miles south of Smokey Bear Road over Labor Day weekend, Friday, August 30, at 5 a.m. to Tuesday, September 3, at 5 a.m. Motorists should expect delays and congestion and are advised to plan ahead, avoid the area, and use an alternate route.

Southbound I-5 is not affected — all four lanes will be open during the holiday weekend. The Frazier Mountain Park on-ramp, which has been closed, will also be open.

The lane reduction is due to a traffic split required for a pavement improvement project on I-5 between Vista Del Lago Road and the Kern County line. The split is necessary so that crews can pave the #3 lane. At the traffic split, motorists in the #3 lane will merge into either the #2 or #4 lane.

Closure information for this and other freeway projects is available on the Caltrans website: http://www.lcswebreports.dot.ca.gov/lcswebreports/

For the safety of the construction crew and motorists, please be attentive to closures and slow for the cone zone.
