Plan ahead, adjust your travel times, and share the ride — that’s the message from the Los Angeles County Metropolitan Transportation Authority.
The 405 Freeway Wilshire ramp closures started at 10 p.m. Friday night. Construction of the westbound and northbound on and off-ramps from Wilshire is expected to take 90 days.
Reconstruction of all eight Wilshire ramps is expected to take more than one year.
These closures and the subsequent reconstruction of the other six Wilshire ramps are expected to create significant temporary impacts to Wilshire Boulevard and adjoining streets, such as Federal Avenue, Sepulveda Boulevard and Veteran Avenue. Sunset Boulevard and Santa Monica are recommended alternatives.
Building the new ramps will reduce the conflict between Wilshire Boulevard and the I-405 as it crosses Wilshire Boulevard. In turn, this should reduce backup at other north/south streets, such as Westwood Boulevard and Veteran Boulevard.
Below is a detailed schedule of upcoming work and the resulting detours for the “ramp-jam” blockades.
