Washington State Department of Transportation crews will close lanes and ramps on SR 520 and I-90 next week.
Drivers should plan for possible delays and detours at night next week as crews close lanes and ramps between Seattle and Bellevue.
The work is part of a project to install sign bridges that will hold new electronic signs to display variable speed limits, lane status and real-time traffic information.
