Jamzilla is coming: Unprecedented 80-hour paving operation planned for northbound 405 Presidents' Day weekend

Los Angeles transportation officials are alerting I-405 and regional freeway motorists of an unprecedented 80-hour northbound I-405 freeway lane closure operation in the Sepulveda Pass this Presidents’ Day weekend, February 14 to 18, 2014.

The Los Angeles Metropolitan Transportation Authority (Metro), in conjunction with California Department of Transportation (Caltrans), Los Angeles Department of Transportation (LADOT), and a host of law enforcement and emergency response agencies throughout L.A. County are giving the public advance notice that if they do not have a critical need to travel northbound through West Los Angeles and the Sepulveda Pass during the Presidents’ Day three-day weekend, they should eliminate unnecessary auto trips, avoid the area and/or divert to other freeways to avoid major traffic delays.

Traffic conditions on local streets and freeways within the region of Los Angeles County and beyond could become severe, with significant, hours-long delays if motorists do not cooperate with authorities and limit northbound freeway trips.

Motorists who must travel during this weekend are advised to prepare their itineraries in advance, monitor real-time traffic conditions prior to beginning their trips and follow alternate routes that are provided. Motorists will be continually informed of the closure in advance by Caltrans-operated freeway message signs.

The I-405 contractor will be paving a major segment of the future northbound I-405 High-Occupancy Vehicle (HOV) lane in the Sepulveda Pass. The work is considered key to meeting the project’s scheduled completion date of 2014.

Work over the Presidents’ Day weekend will eliminate the need for several consecutive 55-hour freeway closures from the project schedule. This closure operation will save significant time and minimize future closure impacts to the community and traveling public.

The closure operation consists of a partial day-time lane reduction and a full night-time directional freeway closure on the northbound I-405 between Getty Center Drive and Ventura Boulevard.  The closure area is approximately 5.6 miles long, or nearly two-thirds of the entire I-405 project area.

During daytime hours, two northbound lanes will remain open while the remaining three lanes will be closed.  During night-time hours, all five northbound freeway lanes in this area will be closed.

The southbound I-405 will remain fully open during the day, but some southbound lanes may be closed during night-time only paving operations.

Work is scheduled to begin Friday night, February 14 starting at 11 p.m. and will last until Tuesday, February 18 at 6 a.m.

Ramps within the project area will begin to close as early as 7 p.m. Traffic officers provided by LADOT will help guide motorists at each I-405 northbound on-ramp.

Full northbound night-time freeway closure times are as follows:

  • Friday night, February 14 – 1 a.m. to 6 a.m.
  • Saturday night, February 15 – 2 a.m. to 7 a.m.
  • Sunday night, February 16 – 12 a.m. to 5 a.m.
  • Monday night, February 17 – 12 a.m. to 5 a.m.

The designated alternative route for night-time full closures will be for motorists to take the Wilshire northbound to westbound off-ramp to northbound Sepulveda Boulevard, returning to northbound I-405 at the Greenleaf northbound on-ramp.

Sepulveda Boulevard also will be fully open with two lanes in each direction during the paving operation.  However, Sepulveda Boulevard will not have the capacity to accommodate all diverted northbound freeway traffic, and could become severely congested. Freeway motorists should instead divert to other freeway routes.

I-10 connectors to the northbound I-405 also will be closed. Motorists detouring from the closed I-10 connectors should use freeway detour routes rather than local streets.

The connector detour routes will be as follows:

  • For eastbound I-10 to northbound I-405 – use northbound I-110, northbound US 101, to northbound I-405.
  • For westbound I-10 to northbound I-405 – use northbound I-5, westbound SR 134, northbound US 101, to northbound I-405.

The construction schedule is subject to change, and paving work is dependent on favorable weather conditions. In the event of inclement weather during the 80-hour closure, the project will commence continuous 55-hour weekend closures of the northbound freeway starting the following weekend, February 21 for up to four weekends to complete the originally intended work.

The I-405 Sepulveda Pass Improvements project has now concluded most major freeway widening work between the I-10 and U.S. 101. The contractor is now building the future northbound HOV lane that will connect West Los Angeles with the San Fernando Valley.

The project will officially complete the last remaining gap in the entire I-405 lane network.  Additional project benefits include improved freeway safety through standardized lane and shoulder widths, greater ramp capacities at key locations, new sound and retaining walls, widened overpasses, widened and seismically updated bridges.

The project is a joint effort between Metro and Caltrans, and is being constructed by Kiewit Infrastructure West Co.

  1. Biggest waste of tax payer dollars since the bridge to nowhere… And this is a freeway to nowhere…. The misery can only be described by someone with a lot more artistic attributes that I do

  2. This whole project is so stupid. Nobody wanted a dumb carpool lane. If you would have build additional regular lanes AND mass transit, Id be ALL for this. How is there no direct rail system from WLA to the SFV? Who thinks of this stuff? I swear its all political graft.

    Even the new “Crenshaw” rail line you guys have screwed up! No airport connector and it doesn’t even start at Wilshire anymore. FAIL!

  3. Who is the moron city planner that decided to close the 405 the same weekend at the Northern Trust Open at Riviera country club! That event by itself puts the Westside in gridlock, now add a restricted 405 – the Westside will be in meltdown!

  4. Any idea when they are going to do the Southbound lanes? Not sure if a holiday weekend is any better than any other weekend. It is going to be a mess on the Westside of LA.

  5. I wish they’d build a train going through the middle of the freeway like the 105 and 210 have.

  6. luckily, once this is complete, the hundreds of thousands of people that use this corridor daily will have an alternative, traffic-free, environmentally-friendly, safe and reliable method to travel between the Valley and the Westside (and points further south)… OH WAIT! This project will do NOTHING in that respect at all – it will simply provide yet another lane that will be congested within days of opening. And we will still not have a reliable TRANSIT link between these major areas. Good job, Metro, you’re spending over $1 billion for more traffic congestion.

  7. All the money, misery and human suffering that they’ve inflicted upon the public by keeping the 405 under continuous construction for a dozen years will soon be over, because they’ll finally finish building a stupid carpool lane. And what will they undoubtedly do with OUR carpool lane once it’s been built on the billions of hours of human suffering and dollars? Undoubtedly they’ll sell OUR lane to some private company who wants to implement congestion pricing so wealthy bastards can have their own private freeway lane and the rest of us can continue to enjoy INCREASED suffering in WORSE traffic! YAY the wonks say it’ll be great to give the rich their own private lane of freeway, the benefits of the rich having their own private lane will TRICKLE DOWN to the rest of us. Just like the wonks said it’ll be great to give the rich massive tax breaks because the benefits the rich will enjoy will trickle down to the rest of us. But the outcome will be the same, we are all going to be much worse off when they sell OUR lane off to the plutocracy.
