Northbound 405 Offramp to Sunset Blvd. Closes for 4 Months

The closure begins Aug. 3. Detours will be in place, including advisories via portable message signs.

The contractor for the 405 Freeway widening project is scheduled to begin a 120-day closure of the northbound I-405 off-ramp to Sunset Boulevard in West Los Angeles beginning Aug. 3.
The closure is required to complete building a longer off-ramp that, when complete, will be 60 percent longer than the current off-ramp, according to Metro.

Northbound freeway motorists that normally use the Sunset off-ramp to access Westside destinations are encouraged to plan ahead to determine alternate routes, allow extra time to reach destinations, eliminate unnecessary trips to avoid peak congestion and/or consider ridesharing and public transit options.
The new configuration will feature two northbound right-turn lanes to eastbound Sunset and one northbound left-turn lane to westbound Sunset.
Detours:
Westbound Sunset

• Daytime: Northbound I-405 off-ramp to westbound Wilshire Boulevard, to northbound Sepulveda Boulevard, to eastbound Sepulveda Way, to westbound Sunset Boulevard.
• Alternate: Moraga Drive off-ramp, to southbound Sepulveda Boulevard, right on Church Lane to Sunset Boulevard.
• Nighttime: Northbound I-405 off-ramp to westbound Wilshire Boulevard, right on northbound San Vicente Boulevard, right onto north Barrington Avenue, left onto westbound Sunset Boulevard.

Eastbound Sunset

• Northbound I-405 off-ramp to eastbound Wilshire Boulevard, to northbound Veteran Avenue to eastbound Sunset Boulevard.

  

Existing Conditions During 120-Day Closure

• Sepulveda Way acceleration lane will remain open as is.
• Sepulveda Boulevard and Church Lane intersection will see lane reduction and height restrictions.
• Temporary false work bent at the median will be added at Bronwood and Sepulveda; left-turn restrictions will apply.
• Sepulveda Boulevard will operate at full capacity in peak directions during peak hours.
• Sepulveda Boulevard fully closed from Montana Avenue to Moraga Drive at night from 10 p.m. to 6 a.m. 

The project team will deploy traffic control officers to key locations in the morning and afternoon peak period, and traffic control strike teams will patrol and monitor the area. Portable message signs will be used to advise motorists of the closure in advance. 
Project improvements at Sunset Boulevard, including complete reconstruction and widening of the Sunset Bridge over the I-405, widening of the Church Lane undercrossing and construction of area retaining walls constitute some of the project’s most significant roadway improvements.
