The northbound 405 Freeway will be closed during the weekend as construction workers prepare for the final demolition phase of the Mulholland Bridge.
Northbound lanes and freeway ramps between Getty Center Drive and Ventura Boulevard will close at 11 p.m. Saturday. The lanes and ramps are scheduled to reopen at 9 a.m. Sunday.
Ramps might close as early as 7 p.m., according to transportation officials.
The project comes ahead of what has been dubbed Carmageddon II -- the Sept. 29 and 30 closure of the 405 Freeway for demolition work on the Mulholland Bridge. The 405 Freeway will be closed from the 10 Freeway to the 101 Freeway.
The freeway is expected to reopen on the morning of Oct. 1.
"The entire demolition operation is meticulously planned," said Metro spokesman Dave Sotero. "The contractor has the schedule buttoned down to a 15-minute schedule, so every 15 minutes they know where they need to be in the project schedule in order for the freeway to reopen. There will be no uncertainty as to what they need to get done when."
The southbound lanes of the 405 Freeway were closed through the pass last weekend.
