Drivers beware: more nighttime closures are scheduled to begin Monday for the 405 freeway as construction crews demolish the northern side of the Sunset Boulevard bridge.
One side of the freeway will be closed at a time for up to one mile near the bridge, according to Metro.
Demolition work is scheduled for overnight hours in an effort to minimize traffic congestion. Ramp closures will start around 7 p.m. followed by freeway lane closures around 10 p.m., Metro said. Full freeway closures are expected between 12 a.m. and 5 a.m. weekdays, and 12 a.m. and 7 a.m. weekends.
Additional daytime closures for certain parts of the project are also planned.
"On any given day there can be 30 to 40 closures on the project, " said Dave Sotero, Metro spokesperson.
Street closures in the area will be in place from 9 p.m. to 6 a.m.
Northbound 405 traffic will be detoured off the freeway at the Montana Ave off-ramp to Northbound Sepulveda Boulevard, back to Northbound I-405 on-ramp at Moraga Dr.
Southbound I-405 traffic will be detoured from Sunset Boulevard off-ramp to Northbound Church Lane, to Southbound Sepulveda Boulevard, to Westbound Wilshire Boulevard on-ramp to Southbound I-405, Metro said.
The majority of the demolition will be done by mid-November followed by 12 months of reconstruction to the new north-side of the bridge.

The work is all part of the $1 billion I-405 Sepulveda Pass Improvements Project which will add a new 10 mile carpool lane on the northbound 405 between I-10 and U.S. 101.
Other improvements include improved ramp capacities at key locations, wider overpasses, and seismic upgrades to sevral bridges, Metro said.
