Drivers should plan possible delays and detours at night this week as crews working for the Washington State Department of Transportation close lanes and ramps on SR 520 and I-90 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.
