Nighttime 405 lane closures for Crenshaw/LAX Line construction begin July 31

Fifteen nights of full and partial closures on the I-405 freeway will begin Monday, July 31, to accommodate construction of a bridge for the Crenshaw/LAX Line. The work is being done by Walsh Shea Corridor Constructors, the contractor building the project for Metro.

The lane closures are needed for the safe removal of the wood framing used to build the 800-foot-long bridge that spans the 405, Hyde Park Avenue and La Cienega Boulevard.

The nightly full and partial directional closures will be from 10 p.m. to 5 a.m. Monday through Friday. The freeway will be fully open during the weekends.

Closure Schedule:

  • July 31 to Aug. 4: northbound lanes will be completely closed between Century and La Tijera Blvd.
  • Aug. 7 to Aug. 11: partial closure of the north and southbound High Occupancy Vehicle (HOV) lanes and the 1 and 2 lanes.
  • Aug. 14 to Aug. 18: southbound lanes will be fully closed between the La Cienega off-ramp and La Tijera on-ramp.

Detours:

  • If traveling southbound, exit the 405 at the Florence/Manchester off-ramp, proceed south on La Cienega and return to freeway via the Olive Street on-ramp.
  • Motorists heading to Los Angeles International Airport can remain on La Cienega to access Century Boulevard or re-enter the 405 and use the westbound 105 and Sepulveda Boulevard to reach LAX.
  • If traveling northbound, exit at the Florence/Manchester off-ramp, turn left (west) on Manchester, turn right (north) on La Cienega, then left on Centinela and then left on La Tijera and continue to the northbound 405 on-ramp.

 

Closure dates are tentative and subject to change based on construction progress and weather conditions. The bridge is expected to be completed in 2018 and the Crenshaw/LAX Line to open in fall 2019.

LAX encourages passengers to arrive at their terminal two hour before boarding time for domestic flights and three hours before boarding time for international departures.

Metro apologize for the inconvenience that these nightly closures may cause and urges motorists to plan ahead and to expect some delays.

  1. Another possible detour southbound to LAX would be to exit the 405 earlier on the Howard Hughes Parkway, and take the first left on Sepulveda. The turnoff for the airport is just after you pass the north runway (where it joins with Lincoln Blvd).

  2. (1) There is no southbound 405 offramp to La Cienega. five different southbound 405 offramps provide access to La Cienega (Florence/Manchester, Century west, Century east, Imperial, El Segundo).
    (2) It is physically impossible for the south 405 to be closed from ANY of those offramps to La Tijera, which is encounter BEFORE one encounters any of the ramps that can access La Cienega (but which are not marked La Cienega).
    (3) Your map shows the southbound closure will not start at La Tijera, like your copy infers. It says the closure will start at Florence/Manchester and end just south of Manchester.

  3. La cienega exit pases under the bridge that they are working wont this exit also be affected by the construction.
