Evening work to snarl traffic on I-5, I-405 this week
Apr 2, 2024, 4:55 PM
Drivers beware. An abundance of evening work will snarl traffic on Interstate 5 (I-5) and Interstate 405 (I-405) this week.
Bellevue work ahead
For the next two weeks, contractors working for the Washington State Department of Transportation (WSDOT) will repair sections of guardrail and replace guardrail protective end caps, or crash cushions at the I-405/State Route (SR) 520 interchange in Bellevue.
This is part of the Northwest Region Breakaway Terminal Cable Replacement project, across King, Snohomish and Whatcom counties. The project aims to repair and update damaged guardrails and end caps to withstand today’s heavier electric vehicles.
Between 9 p.m. and 5 a.m., drivers will see nightly closures at the I-405 north exit ramp to SR 520 west. A detour will send drivers SR 520 east to the 148th Avenue Northeast exit, from there drivers can access SR 520 west.
Work is scheduled on weekdays only, wrapping up Friday, April 12.
