Dubbed “Jamzilla,” the closures affected a nearly six-mile stretch of freeway from Getty Center Drive to Ventura Boulevard.

The work was scheduled to be completed at 6 a.m. on Tuesday, according the Los Angeles Metropolitan Transportation Authority.

However, the CHP tweeted around 5 a.m. that all lanes had been reopened.

The construction was part of a $1.1-billion project to build a northbound carpool lane through the Sepulveda Pass.

Closing the northbound portion of the freeway over the weekend allowed crews to pave and re-stripe the highway, where the high-occupancy vehicle lane was being added.

“We expect that, in the summer, that we’ll be all done with the 405 work,” said Paul Gonzalez, spokesman for Metro. In “July or August, we should see the whole thing open. When that occurs, you’re going to have this brand-new, modern freeway that’s going to meet our needs for the next 50, 60 years.”

By 10 p.m. Sunday, traffic began backing up in the northbound lanes near Getty Center Drive, two hours before all five lanes were again scheduled to close for construction overnight.

The shutdowns through the Sepulveda Pass will allow workers to pave and re-stripe the highway where a carpool lane is being added.

While there were some delays on Saturday night, official said motorists  mostly heeded their warnings, and avoided the area.

“We see a lot of red on the maps on PCH, the 101 and 110. So we know people are going around the area, but maybe they are not cutting back on their trips like they did with Carmageddon 1 and 2,” said Patrick Chandler of Caltrans.

The closures were set in motion for construction on the freeway.

The work began on Friday night at 10 p.m., and was expected to be finished around 6 a.m. Tuesday, according to the Los Angeles Metropolitan Transportation Authority.

Officials urged motorists to avoid the freeway during the long Presidents Day weekend.

“We do encourage everyone to stay away from the area.  Enjoy your time at home and let’s get through the ‘Jamzilla’ together,” said Battalion Chief Don Reyes of the Los Angeles Fire Department.

Earlier, officials had expressed concern about congestion on the suggested detours and alternate routes.

“You see a lot of red on the maps, on” Pacific Coast Highway, the 101 Freeway and the 110 Freway, said Caltrans spokesman Patrick Chandler. “So we know people are going around the area, but maybe they’re not cutting back on their trips like they did for Carmageddon I and II,” he said, referring to previous closures on the 405 Freeway.

Dubbed “Jamzilla,” the current closures were slated to affect a six-mile stretch of northbound lanes from Getty Center Drive to Ventura Boulevard.

Southbound lanes were expected to remain open during the day, though transportation officials advised that there may be some lane closures on that side of the freeway at night.

The connector ramps from the 10 Freeway to the northbound 405 Freeway would also be closed, according to Metro.

The shutdowns through the Sepulveda Pass will allow workers to pave and re-stripe the highway where a carpool lane is being added.

Final preparations were underway early Friday for an 80-hour closure of lanes along a six-mile stretch of the 405 Freeway this Presidents Day weekend.

The closures, which have been dubbed “Jamzilla,” will affect the northbound portion of the 405 Freeway through the Sepulveda Pass. They are scheduled to begin Friday night at 10 p.m. and last through Tuesday morning at 6 a.m., according to Los Angeles transportation officials.

Just two northbound lanes between between Getty Center Drive and Ventura Boulevard will be open during the day, while all lanes will be closed in that direction at night.

The full and partial closures were being enacted so that crews could finish a new carpool lane.

Work crews were busy Tuesday preparing for another big 405 Freeway closure as part of an ongoing construction project in the Sepulveda Pass, officials said.

The closure, unofficially dubbed “Jamzilla,” will block off multiple northbound lanes of the freeway from February 14 to 18, according to the Los Angeles County Metropolitan Transportation Authority.

To prepare for the Presidents Day weekend closure, the contractor has been busy installing electrical equipment at Bel Air Crest Road, transit officials said.

Bel Air Crest Road was scheduled to be reduced to one lane with flaggers, from Tuesday, January 28 to Friday, January 31, according to the MTA.

The work was scheduled to take place each day between 9 a.m. and 3 p.m., officials said.

Once the February closure gets underway, a 5 ½ mile stretch of the freeway will be blocked off between Getty Center Drive and Ventura Boulevard for 80 hours, the MTA said.

Two of the route’s five northbound lanes will be closed during daytime hours, officials said.

All five lanes will be closed between 12 a.m. and 7 a.m.

The southbound I-405 will remain open, but one or two lanes will be reduced during paving operations in the evening.

The February closure comes more than two years after “Carmageddon” and more than one year after “Carmageddon II,” in which sections of the freeway were shut down while bridges at Mulholland Drive and Sunset Boulevard were rebuilt.

Another days-long closure — unofficially dubbed “Jamzilla” — has been scheduled for the 405 Freeway as part of an ongoing construction project in the Sepulveda Pass.

Multiple northbound lanes will be temporarily closed Feb. 14-18 during the 80-hour closure, according to the Los Angeles County Metropolitan Transportation Authority. A 5 ½ mile stretch of the freeway will be closed between Getty Center Drive to the south and Ventura Boulevard to the north.

Two of the route’s five northbound lanes will be closed during daytime hours, officials said. All five lanes will be closed between 12 a.m. and 7 a.m.

The southbound I-405 will remain open, but one or two lanes will be reduced during paving operations in the evening.

“The alternative to one 80-hour closure would be conduct six separate 55-hour closures over six consecutive weekends,” Metro said in a statement.

The February closure comes more than two years after “Carmageddon” and more than one year after “Carmageddon II,” in which sections of the freeway were shut down while bridges at Mulholland Drive and Sunset Boulevard were rebuilt.

Correction: An earlier version of this article originally gave the incorrect timeframe for “Carmageddon” and “Carmageddon II.”
