Coordinated Weekend Closures Hit I-5, I-405, and SR 520 Across Puget Sound
Multiple major road closures and lane reductions are scheduled across the Puget Sound region from Friday night through Monday morning, affecting Interstates 5 and 405, State Route 520, and State Route 99. The disruptions stem from simultaneous infrastructure projects, including bridge preservation, drainage improvements, and paving work. Drivers are advised to expect significant congestion and plan alternative routes, particularly for trips to Seattle-Tacoma International Airport and the eastside.
