The Washington State Department of Transportation (WSDOT) is planning to close a section of I-405 in Bothell, Washington in early March 2026 to safely remove the northbound I-405 to SR 522 ramps. The closures are expected to cause two to three-mile backups, impacting local businesses, residents, and commuters in the area. While the project aims to enhance the highway, the disruption has raised concerns about the human cost of progress and the need for better public engagement and creative solutions to minimize the impact on the community.

Why it matters

This closure is part of a larger infrastructure project to expand and enhance 4.5 miles of I-405, highlighting the ongoing tension between urban growth and the capacity of our transportation systems. The situation underscores the need to rethink how we approach infrastructure projects, explore less disruptive construction methods, and invest in alternative modes of transportation to reduce our reliance on highways.

The details

The upcoming closures are necessary to safely remove the remaining northbound I-405 to SR 522 ramps. WSDOT expects two to three-mile backups during the closures, with the southbound detour funneling traffic through the already congested Bothell Everett Highway. This will have a significant impact on local businesses, residents, and daily commuters in the area.

  • The I-405 closures are scheduled for early March 2026.
