CAJON PASS (KABC) -- Southern California drivers heading to Las Vegas this weekend should plan ahead because of the so-called "Cajon Crawl."
Two northbound lanes of the 15 Freeway, between Highway 138 and Oak Hill Road, closed around 10 p.m. Friday and will not reopen until 3 p.m. Monday.
For most of the weekend, traffic will be reduced to two lanes. But during off-peak hours, only one northbound lane will be open.
The Cajon Pass Rehab Project is replacing old concrete slabs. According to Caltrans, paving over 55 hours allows the concrete to settle, which creates a longer life span.
This is the first of five weekends of extended closures on the 15 Freeway. The only upcoming weekend without lane closures will be Labor Day Weekend.
Southbound lanes through the Cajon Pass will not be affected.
