The Wilshire Boulevard ramps will be demolished and reconstructed to build a 10-mile carpool lane on the northbound I-405 between the 10 and 101 freeways as part of the I-405 Sepulveda Pass Improvements Project.
Westbound Wilshire Boulevard on-ramp to the northbound I-405: Drivers are encouraged to travel northbound on Sepulveda Boulevard to access the Moraga Drive on-ramp, or travel southbound on Sepulveda Boulevard to access the Santa Monica Boulevard on-ramp.
Northbound I-405 off-ramp to westbound Wilshire Boulevard: Motorists should exit the freeway using the Santa Monica Boulevard off-ramp, then head northbound on Sepulveda Boulevard to Wilshire Boulevard.
As an alternative, drivers traveling northbound on the I-405 and westbound on the 10 Freeway will be directed to exit at Bundy Drive to reach their westbound Wilshire Boulevard destinations.
Officials said crews will be working night and day to finish the project as quickly as possible.
