I-405 Metro Banner 



Updated on August 23, 2012




This webpage is dedicated to providing travelers, motorists and airport employees with information, resources and tips so you can PLAN AHEAD to avoid as much as possible the severe traffic congestion expected the weekend of Saturday, September 29 through early morning Monday, October 1, 2012. The traffic delays will be due to a scheduled 10-mile (16-kilometer) closure of the I-405 San Diego Freeway between the I-10 Santa Monica Freeway on the south and U.S. 101 freeway on the north. This segment of freeway is known as the Sepulveda Pass. The closure is the second phase of the demolition of the Mulholland Street Bridge overpass. The first phase demolished the south side in July 2011, which also required the complete closure of the I-405 through the Sepulveda Pass. Last year’s demolition and forecasts of severe traffic congestion and delays lead to the project being dubbed “Carmageddon.”

The I-405 is the busiest freeway in the entire United States. It is a major north-south artery that connects the San Fernando Valley and northern Los Angeles County to other parts of Los Angeles. The I-405 freeway also serves the densely populated Los Angeles Westside and Southern California coastal communities, and is the primary freeway serving LAX. Half a million motorists drive this portion of the I-405 over a typical weekend.

Traffic on the I-405 in both directions will be diverted around the closure onto surface streets and to other freeways in the region which merge near downtown Los Angeles. Click here for map of area:  

I-405 Freeway Closure Schedule: 

  • Friday, September 28 as early as 7 p.m.: ramps and connectors to the freeway begin closing
  • Friday, September 28 as early as 10 p.m.: freeway lanes begin closing to ensure full freeway closure at midnight
  • Saturday, September 29 at 12 a.m. (midnight): full freeway closure all day
  • Sunday, September 30: full freeway closure all day
  • Monday, October 1 at 5 a.m.: freeway lanes begin opening
  • Monday, October 1 by 6 a.m.: ramps and connectors finish reopening

Impacts to Air Travelers, Motorists, and Airport Employees  

General Airport Operations:

LAX is forecasted to serve more than 172,000 passengers each day on September 29 and 30. A daily average of 66,000 vehicles are expected to come to LAX that weekend. While less than on weekdays, approximately 20,000 airport-wide employees are scheduled to work each weekend day. Operationally, the airport-wide community will be challenged to ensure weekend employees of airlines; airline contractors who provide baggage handling, aircraft cleaning, catering, and other services; federal security screening and immigration/customs agencies; law enforcement; ground transportation providers, etc. report to work on time so passengers do not encounter delays due to lack of staff.

Friday nights and Monday mornings are two peak travel periods at LAX. On Friday night beginning at 7 p.m., when on- and off-ramps and the number of lanes are gradually reduced to full closure, thousands of passengers are expected to arrive and depart LAX. The passenger volume especially peaks for departing international flights between 7 p.m. to 1 a.m. On Monday morning beginning at 4 p.m. to 9 a.m., when the freeway will gradually reopen, thousands of passengers are expected to arrive at LAX for the morning wave of domestic departures.

Flight Operations:

Flights at LAX are expected to operate normally the weekend of September 29-30. Passengers who miss their flights without advance notice or cancellation to their airlines are generally expected to pay fees that airlines charge for rebooking flights. So, it is important that passengers ensure they arrive on time for their departure flights.

Traffic Conditions:

Motorists driving northbound or southbound I-405 will be redirected to other regional freeways. NO special consideration will be given to whether the motorists are driving private vehicles or public transportation vehicles, such as taxi cabs, municipal and long-distance buses, door-to-door shuttle vans, limousines, etc.).

Motorists driving to or from the north of LAX (i.e., San Fernando Valley, northern Los Angeles County, and further north of the metropolitan L.A. area) should expect to be redirected to other regional freeways – most of which lead to downtown Los Angeles. From downtown L.A., freeway traffic will be diverted back to westbound I-10 Santa Monica Freeway to return to the L.A. Westside and beach communities. This detour is approximately 25 miles (40 kilometers).

Motorists driving to or from coastal communities north of LAX (i.e. Venice, Santa Monica, Malibu, etc.) should expect Lincoln Boulevard and Pacific Coast Highway to be congested.

Motorists driving to or from Santa Barbara and Ventura counties west of Los Angeles will find the I-405 completely closed. Motorists have the option of using north-south surface streets from US 101 to Pacific Coast Highway to Lincoln Boulevard leading to LAX.

Motorists driving to or from east or south of LAX may initially believe they will be unaffected because they are coming from directions away from the freeway closure area. However, airport officials advise motorists prepare for traffic congestion as they approach the exits from the primary freeways serving LAX: the I-405 and the I-105 Century freeways. Major surface streets leading to/from LAX may also be congested: Imperial Highway and Century Boulevard on the east; and Sepulveda, Aviation and Hawthorne boulevards on the south.

General Travel Advice  

Plan ahead. Use public transit, especially a combination of local or regional rail and the LAX FlyAway® nonstop bus service at Union Station. If you must drive, avoid impacted areas and minimize the number of vehicle trips.

Following are general guidelines for checking in for a departing flight:

  1. Arrive in your airline ticketing/check-in lobby two hours before departure time for domestic U.S. flights and three hours before an international flight.

  2. Save time at the airport by checking in on your airline’s Internet website within 24 hours of your departure time to obtain an electronic boarding pass. This will allow you to go straight to federal passenger security screening. You can also pay any fees charged by airlines for checked luggage and obtain boarding passes before coming to the airport. Airlines have separate lines for passengers who already have their boarding passes and simply need to check their luggage.

  5. Special Tips for Arriving Passengers

    Passengers flying into LAX during the weekend of September 29-30 should expect traffic congestion on the roadways and freeways after they exit LAX. For the most part, arriving passengers leave the airport using one of the following ways:

    1. Friends, relatives or business colleagues pick them up in personal vehicles.

    2. Tour operators meet them with buses.

    3. They take shared-ride public transportation such as a taxi, door-to-door shuttle van, long-distance bus, LAX FlyAway® bus, Metro Rail Green Line, municipal bus, and hotel courtesy shuttle van.

    4. They rent a vehicle.

    5. They use their own vehicle parked at or near the airport.

    6. They connect on an outbound flight and have no need for local transportation.

      If you are familiar with Los Angeles and someone would normally meet and pick you up at LAX, help reduce his/her drive time and the number of vehicle trips to and from LAX by taking shared-ride public transportations from LAX to your home, hotel, business or public transit stop closest to your local destination. For public transit options, see the sections above on:
      A. Leave your car in the garage and share a ride.
      B. Ride the rails and take the LAX FlyAway® bus at Union Station.  

      If you are renting a car, the car rental company’s employees will be monitoring real-time traffic conditions and can provide you with the best route to your local destination. Ensure the rental agency employee provides you with a map showing the location of the freeway closure, the recommended diversion routes, and up-to-the-minute information on traffic conditions before you set out. If traveling with children, ensure items you would normally bring on a car trip with children (such as snacks, beverage, toys music, etc.) are within easy reach.

  6. Fly by helicopter

Project Background  

The Los Angeles County Metropolitan Transportation Authority (Metro) and the California Department of Transportation (Caltrans) are undertaking a $1-billion I-405 Sepulveda Pass Improvements Project that will reduce congestion, improve mobility and increase safety. The project will add a high-occupancy vehicle (HOV/carpool) lane, standardize traffic lanes, and improve on- and off-ramps along a 10-mile-long stretch of the I-405 San Diego Freeway between I-10 Santa Monica Freeway on the south and US 101 Ventura Freeway on the north. In July 2011, the demolition of the south side of the Mulholland Street Bridge overpass was undertaken, requiring the closure in both directions of I-405. Mulholland Street Bridge is one of three overpasses to be demolished and reconstructed as part of the overall project. The scheduled I-405 closure in both directions on September 29-30, will allow demolition of the other side of the bridge. For more info:
