Motorist alert!: upcoming 10-hour northbound 405 closures this weekend

Here's the news release from Metro:

Full 10-Hour Northbound I-405 Freeway Closures at Santa Monica Boulevard in West L.A. Planned May 17, 18

The I-405 Sepulveda Pass Improvements Project contractor is scheduled to conduct two additional full 10-hour northbound I-405 freeway closures from the Santa Monica Boulevard off-ramp to the Santa Monica Boulevard on-ramp in West Los Angeles on the nights of Friday, May 17, and Saturday, May 18, 2013 from 11 p.m. to 9 a.m.

Because these closures are twice as long as the normal five-hour night-time freeway closures, motorists are advised to plan ahead, avoid the area or take alternate routes to avoid traffic congestion.

The contractor will continue to repair the approach slab at the connection between the I-405 freeway and the Santa Monica off-ramp. Similar work was completed last weekend on May 10.

• Northbound Santa Monica Boulevard off and on-ramps will remain open.

• Detour: Exit at the Santa Monica Boulevard off-ramp, go straight through traffic light and enter the Santa Monica Boulevard on-ramp.

• Traffic control officers will be deployed.

• CHP will be monitoring the area surrounding the closure.

The following ramps will be closed during the 10-hour closures:

• Northbound Olympic Boulevard on-ramp

• Santa Monica Boulevard from Sawtelle Boulevard to Sepulveda Boulevard

• I-10 west connector to northbound I-405

• I-10 east connector to northbound I-405

What to expect:

• Construction schedule is subject to change based on daily progress and field conditions.

• Notification of ramp closures will be provided on a daily basis through the PM Closure e-mail notices. Subscribe to daily e-mail alerts at​

  1. And while we’re at it, why is east-west traffic on Santa Monica Blvd. not closed off to allow northbound 405 traffic to free-flow through the detour? The NB 405 backed up to Artesia Blvd. last weekend. And finally, why is Metro closing EB Pico on the same weekends that thiere are major 405 closures? You should have seen Olympic and other nearby streets in WLA. This is not brain surgery.

  2. Last weekend, the 405 freeway was not reopened until 10:30 due to wet cement. So be it. But I could help but noticing that on the same weekend that Metro had the 405 north closed, Caltrans had (a) half of the northbound 101 lanes closed at Sunset for the entire morning, and (b) poor little State Route 27, Topanga Canyon Blvd., operating with flaggers and one lane for guardrail repair. My question is this: do Caltrans and Metro do this on purpose, to spite one another? Or are they just unable to look at the big picture and coordinate major closures like this?
