Once more into the breach, dear friends! Or in this case, once more into a weekend with a full closure of I-405. If you’ve been following along the past few weeks, you know we’ve been working to remove the old SR 522 flyover ramp over I-405 in Bothell. This weekend is the final push to take down the remaining sections over the freeway. To safely do that work, both directions of I-405 will fully close in Bothell this weekend. Let’s get into the closure details:
WHAT THIS MEANS FOR DRIVERS: This closure overlaps with ongoing Revive I-5 work on the Ship Canal Bridge, where two northbound lanes remain closed and express lanes are running northbound only 24/7. Expect significant congestion across the region. Backups of several miles and delays of more than an hour are possible on I-405, and traffic may spill onto local streets and alternate routes that don’t typically carry freeway-level traffic. If you’re heading to weekend events like the Seattle St. Patrick’s Day Parade or a Kraken game, plan ahead, allow extra travel time, consider alternate routes, or take transit if possible. WHY ARE WE DOING THIS: Removing the old SR 522 ramp clears space for the next phase of the I-405/Brickyard to SR 527 project, which will widen I-405 through Bothell and add an express toll lane in each direction of I-405, direct access ramps to the ETLs and will help enable Stride Bus Rapid Transit service. These improvements will benefit drivers, transit riders and freight mobility across the region. Additionally, the project is addressing aging infrastructure, restoring stream connections, adding noise walls and new stormwater facilities. THE FINAL ACT: Take heart, dear travelers. This is the final weekend closure needed to remove the ramp over I-405. submitted by /u/wsdot |
