And you thought things couldn't get worse on the 405 Freeway.
Full-lane closures will begin Jan. 12 as crews begin to widen the road through the Sepulveda Pass. It's the start of a project that will create a 10-mile northbound carpool lane between the Santa Monica (10) and Ventura (101) freeways.
Although the closures will occur during overnight hours, the project is likely to result in about two months worth of added challenges for motorists. Metro's statement warns: "Commuters, residents and businesses in the vicinity should now anticipate upcoming freeway construction impacts and begin planning needed travel alternatives and schedules."
Work will be done on weekdays only, 7 p.m. to 6 a.m. The first month will consist of setting up temporary traffic lanes along the 10-mile Sepulveda Pass freeway segment.
Caltrans will close all lanes on various segments of the northbound stretch as work schedules require, according to Metro. But full freeway segment closures will only take place between the hours of midnight and 5 a.m., according to the transit agency.
Beginning about Feb. 15, workers will begin placing concrete barriers on the 10-mile freeway shoulder to isolate the work zone from existing traffic, resulting in temporary lane closures. That part of the project is also estimated to take about four weeks and will also be done between the hours of 7 p.m. and 6 a.m.
Drivers should expect ramp closures to start as early as 7 p.m., followed by freeway lane closures at 9 p.m.
