Lane closures on I-405

As part of the I-405 Improvement Project, crews will begin testing the 405 Express Lanes system as early as mid-October. Testing will require closures of the I-605 and SR-22 HOV connectors, and may require intermittent lane closures on I-405.

Crews are also performing grinding work and barrier construction intermittently at night on northbound and southbound I-405. This work may be loud. For more information, visit 405expresslanes.com.
