Very late night or early morning drivers should expect full closures on westbound SR 520 in Bellevue and eastbound SR 520 in Redmond this week.

For the next three nights WSDOT crews will close westbound SR 520 in Bellevue to install three overhead sign bridges. These sign bridges will hold high-tech electronic signs that will be activated next summer as part of the new smarter highways system.
