Renton, Wash. (Evening Washington News) August 28, 2026 — A multi-lane traffic obstruction triggered extensive morning commute delays along northbound Interstate 405 on Friday, following an early-morning vehicle collision near the Renton and Bellevue corridor. The incident, which centered around milepost 7 just south of Northeast 44th Street, drew an immediate response from emergency personnel and transportation officials as commuters faced mounting gridlock during the peak early-morning travel window.
What Caused the Initial Gridlock on Northbound I-405?
The disruption began before dawn when a collision occurred on the vital regional artery, prompting swift automated and manual alerts from state transportation authorities. As reported by staff writers at MyNorthwest, multiple lanes of northbound Interstate 405 were blocked early Friday morning after a collision occurred near Northeast 44th Street.
The Washington State Department of Transportation sent out the initial alert at 5:50 a.m., stating that a crash was blocking the HOV lane on northbound I-405, just south of Northeast 44th Street at milepost 7. Based on Department of Transportation traffic cameras, response vehicles and first responders quickly blanketed the scene, cascading closures across the roadway. While initial reports indicated the HOV lane was swiftly isolated, the scale of the obstruction expanded to encompass three right-hand general-purpose lanes as recovery teams worked to secure the area.
How Did Emergency Responders Manage the Scene?
Managing a major arterial blockage during a Friday morning rush hour requires precise coordination between transit monitors and field units. According to updates tracked by MyNorthwest staff, emergency crews and first responders remained heavily stationed at the scene through the early morning hours, keeping multiple lanes restricted while investigating the mechanics of the collision and clearing wreckage.
Visual monitoring via WSDOT traffic cameras provided critical real-time data to dispatchers, revealing that while emergency vehicles managed to clear the leftmost lanes relatively early in the incident lifecycle, the three right lanes remained stubbornly blocked by public safety personnel and towing apparatuses. The fluid nature of the scene meant that for more than an hour, no definitive or estimated reopening time could be reliably established, forcing regional transit networks to handle cascading delays that rippled backward toward State Route 167.

What Were the Alternate Routes Recommended for Stranded Commuters?
With vital transit capacity severely throttled, regional traffic authorities scrambled to provide alternate paths for motorists trapped behind the backup. As highlighted by KIRO Newsradio traffic reporter Chris Sullivan during his live broadcast coverage for MyNorthwest, drivers were strongly discouraged from attempting to push through the bottleneck.
As reported by traffic reporter Chris Sullivan of KIRO Newsradio,
“If you are coming up NB 167 and heading to Bellevue, go west on SB 405 to I-5 and take I-90. You do not want to get on NB 405 right now. Only the HOV lane is open north of 30th.”
This targeted advisory diverted thousands of commercial and passenger vehicles away from the central Renton-Bellevue corridor, utilizing Interstate 5 and Interstate 90 as a functional horseshoe bypass around the crippled stretch of highway. Commuters heading northbound from lower-lying valley zones found themselves heavily reliant on these alternate directions as transit dispatchers continuously updated their digital feeds.
When Were All Lanes Finally Cleared and Reopened to Traffic?
The protracted morning delay finally began to dissipate as field crews completed their on-site investigative sweeps and cleared the disabled vehicles from the roadway shoulders. According to official updates published by MyNorthwest, traffic flow was systematically restored as WSDOT phased out lane restrictions.
Initial updates from transportation dispatchers noted that on northbound I-405 just south of Northeast 44th Street in Renton, the HOV lane and left lane were cleared first, leaving only the two right lanes blocked during the secondary phase of the response. Shortly thereafter, concerted efforts by tow operators and highway maintenance teams successfully cleared the remaining obstacles. MyNorthwest staff confirmed that all impacted northbound lanes of Interstate 405 officially reopened just before 7:15 a.m., allowing residual backup to slowly unwind as standard morning travel speeds gradually returned to the vital Pacific Northwest economic corridor.
