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 light rail project. 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 La Cienega/Manchester off-ramp, turn left (west) on Manchester, turn right (north) 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.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 urge motorists to plan ahead and to expect some delays.
