Seattle Traffic Alert: Water Main Break Causes Major Delays on SR 99 & E. Marginal Way (2026)

Water Main Break Causes Chaos on Seattle's E. Marginal Way

A burst water main on E. Marginal Way in Seattle has caused a major disruption during rush hour, snarling traffic along the northbound lanes of SR 99. The incident occurred just after 7 a.m., with the Seattle Department of Transportation (SDOT) quickly alerting commuters to the situation.

SDOT's tweet at 7:15 a.m. stated, 'Water main break at East Marginal Way S & Diagonal Ave S blocking 3 NB lanes. Use caution and expect delays.' This was followed by the Seattle Police Department (SPD) closing off E. Marginal Way S. between Hudson Street and Diagonal Avenue S. at around 9 a.m., further exacerbating the congestion.

The impact of this break is significant, with S. Alaska Street also closed as of this report. Commuters are advised to plan for delays or consider taking an alternate route. This situation is a stark reminder of the vulnerability of our infrastructure and the potential for everyday disruptions to cause widespread chaos.

As of this writing, the story is still developing, and updates will be provided as more information becomes available. Stay tuned for further details on this developing story.
