Three northbound lanes on the 405 freeway through West Los Angeles will close for 55 hours starting Friday, and Metro officials told commuters to plan for traffic delays.
A 2.4-mile stretch of the freeway between Montana Avenue and Getty Center Drive will be reduced from five lanes to two as part of the Sepulveda Pass Improvements Project. The off-ramps will be closed during the 55-hour period.
All northbound freeway lanes and ramps will reopen to the public by 5 a.m. Monday, according to Metro.
If it rains, the work will be delayed by about one week.
Drivers will be able to bypass the closure by taking Westbound Wilshire Boulevard to Northbound Sepulveda and entering the northbound 405 again at Skirball Center Drive, according to the Los Angeles County Metropolitan Transportation Authority.
During the closure, crews will realign the freeway to incorporate a carpool lane that will eventually extend 10 miles between the 10 and 101 freeways.
