Start prepping your alternate routes now, Angelenos! The I-405 freeway is planning lane closures from September 5 through September 8 in order to repair the Sepulveda Pass.
CalTrans shared the news on August 18. “The freeway will be reduced to three lanes in each direction, and motorists are strongly encouraged to seek alternate routes and explore public transportation options to reach their destinations,” reads the website.
The construction is reportedly part of a $143.7 million pavement rehabilitation project announced in April, fixing streets from Westwood to Van Nuys. It’s set to begin at 10 pm on Friday, September 5, but the entire project will take up to four years to complete.
What lanes will be closed?
Northbound Interstate 405
- Northbound I-405 will be reduced to three lanes between Santa Monica Boulevard to just north of Sunset Boulevard
- Santa Monica Boulevard on-ramp closed
- Wilshire Boulevard off-ramp closed
- Eastbound and westbound Wilshire Boulevard on-ramps to northbound I-405 closed
- Sunset Boulevard on/off-ramps closed
- Sepulveda Boulevard/Moraga Drive off-ramp closed
Southbound Interstate 405
- Southbound I-405 will be reduced to three lanes just north of Sunset Boulevard to eastbound Wilshire Boulevard
- Sunset Boulevard/Church Lane on/off-ramps closed
- Westbound Wilshire Boulevard on-ramp to southbound I-405 closed
What routes should you take instead?
CalTrans recommended alternative routes include:
- Santa Monica Boulevard to northbound I-405: Travel east on Santa Monica Boulevard and north on Sepulveda Boulevard to the on-ramp to northbound I-405 at Moraga Drive
- Sunset Boulevard to southbound I-405: Travel north on Church Lane, south on Sepulveda Boulevard, west on Santa Monica Boulevard to the on-ramp to southbound I-405
How long will the construction last?
The block of work will last from September 5 through September 8, but CalTrans warns that extended weekend lane reductions will occur about every two weeks along various sections of I-405 for approximately 25 weekends. The schedule is also subject to change depending on weather or operational reasons.
Residents and businesses located near the site of construction could experience noise, vibrations, and dust during construction times.
