LOS ANGELES, CA — Traffic is expected to be impacted on the 405 Freeway this weekend when construction shuts down several lanes on both sides of the interstate near the Sepulveda Pass. The roadwork will also shut ramps at three major boulevards on the Westside.

The freeway will be reduced to at least three lanes in each direction roughly between Westwood and the Getty Center beginning 10 p.m. Friday and continuing through 5 a.m. Monday. Additionally, ramps at Santa Monica, Sunset and Wilshire boulevards will be impacted, according to Caltrans.

Several detours will be in effect and motorists are advised to avoid that area of the 405 Freeway where possible.

  • The northbound freeway will be reduced to three lanes between Santa Monica Boulevard and just north of Sunset Boulevard
  • The Santa Monica Boulevard on-ramp will be closed
  • The Wilshire Boulevard off-ramp will be closed
  • The eastbound and westbound Wilshire Boulevard on-ramps to the northbound 405 will be closed
