Motorists traveling through the Sepulveda Pass will encounter overnight lane, ramp and connector closures beginning Monday evening as crews continue work on a $143.7 million pavement rehabilitation project along the San Diego (405) Freeway.
The closures will occur nightly from 9 p.m. to 6 a.m. through Friday, according to Caltrans.
Up to four northbound lanes of the 405 Freeway will be closed between Wilshire Boulevard and Skirball Center Drive/Mulholland Drive, while up to four southbound lanes will be closed between the Ventura (101) Freeway and Skirball Center Drive/Mulholland Drive.
The northbound Getty Center Drive on- and off-ramps and the northbound Skirball Center Drive/Mulholland Drive off-ramp will also be closed.
On the southbound side, the Sepulveda Boulevard and Ventura Boulevard on- and off-ramps will be closed, along with the northbound and southbound 101 Freeway connectors to the southbound 405.
Caltrans said the overnight closures are needed for K-rail installation and paving work. The speed limit will be reduced to 55 mph in certain sections of the northbound and southbound freeway because of the ongoing work.
More extensive restrictions are planned beginning at 10 p.m. Friday, when the southbound 405 Freeway will be reduced to three lanes between Ventura Boulevard and Mulholland Drive through 5 a.m. Oct. 5.
During the extended weekend reduction, the Ventura Boulevard on-ramp to the southbound 405 will be closed, along with the southbound 405 off-ramp to Valley Vista Boulevard/Sepulveda Boulevard and the Valley Vista Boulevard/Sepulveda Boulevard on-ramp to the southbound freeway.
The northbound 405 off-ramp to Getty Center Drive will also be closed.
Residents and businesses near the construction may experience noise, vibrations and dust, Caltrans said.
The work is part of the I-405 Pavement Rehabilitation Project between Van Nuys and Westwood through the Sepulveda Pass. The project is intended to improve safety and mobility and extend the life of the freeway pavement.
