Drivers should plan for delays on SR 99 at Ward Street just north of the Battery Street Tunnel on Monday night, March 8. Crews will close lanes to prepare to build an overhead “sign bridge”. The overhead sign bridge will span the southbound direction of SR 99 and will support an electronic message sign. Crews will return in the spring to install the foundation for the sign bridge and the sign bridge itself.

Crews will close two of three left lanes on southbound SR 99 at Ward Street, and the far left lane of northbound SR 99 also at Ward Street, on Monday from 6 p.m. until 5 a.m.

This work is part of the Intelligent Transportation Systems project. The Seattle Department of Transportation (SDOT) is working in partnership with the Washington State Department of Transportation (WSDOT) to bring more real-time traffic information to drivers on SR 99, and major routes leading to SR 99 in Seattle. The electronic message signs will provide drivers with traffic information such as construction closures, lane status and travel times. Six new electronic message signs will be installed on SR 99 from the First Avenue S. Bridge to N. 137th Street.

Installing real-time traffic information systems now will help keep Seattle moving during construction to replace the Alaskan Way Viaduct in the near future.
