Buckle up for some traffic blues if your commute runs through Bothell. The Washington State Department of Transportation (WSDOT) is prepping for a full shutdown of southbound Interstate 405 from Friday, September 6, to the wee hours of Monday, September 9. This move is a part of the hefty I-405/Brickyard to SR 527 Improvement Project, which aims not only to extend the dual-express toll lanes but also to bolster access to the Sound Transit’s Stride bus service, tackle aging infrastructure, and mitigate ecological hurdles for fish populations, along with the installation of noise-preventing walls.
We're looking at a complete closure of the interstate between State Route 527 and SR 522, starting at 10 p.m. on Friday and lasting until 4 a.m. Monday. Travelers should expect ramp closures, including the SR 527 southbound on-ramp, Northeast 195th Street/Beardslee Boulevard southbound on- and off-ramps, and the SR 522 southbound off-ramp. This vital infrastructure, now showing signs of wear from constant use, requires an overhaul.
A detour will be clearly marked for those caught in the vicinity—though WSDOT warns that it’s not cut out for the regular rush of I-405 traffic, advising folks to "know before you go" or tweak travel plans to dodge peak hours or unnecessary trips during these dates, as per the guidance provided by the department. WSDOT's official announcement outlines the schedule and specifics for those impacted by the shutdown.
"Our crews have been patching as needed, but much of the pavement on this stretch of I-405 in Bothell has reached the end of its useful life and needs to be replaced," said Evelyn Pao, WSDOT's project director. She acknowledged the relentless passage of time and the ongoing cycle of repair and renewal. The closure aims to expedite the work safely and efficiently, as noted in the WSDOT statement. In a world that moves at the speed of the internet, a full closure like this is a rare slowdown—a momentary pause in the rhythm of city life that, while inconvenient, promises smoother travel in the future.
