The proposed SR 16 Nalley Valley Interchange.
This computer-enhanced photo image shows how the Nalley Valley Viaduct will look once the Westbound Nalley Valley project is complete, but before the next two Nalley Valley projects are done. Note westbound traffic will be moved onto the new westbound structure. The green shaded roadway connecting eastbound SR 16 with the old westbound viaduct represents a temporary detour that will be put into place during the Eastbound Nalley Valley project.
Benefits of this first project, which will be under construction between 2008 and 2011, include building a new westbound Nalley Valley viaduct, preparing for future connections of HOV lanes between I-5 and SR 16, rebuilding ramps connecting SR 16 to and from Sprague Avenue, replacing ramps from I-5 to westbound SR 16, constructing stormwater collection and treatment facilities, upgrading signing and illumination, and installing communications devices into the highway to help WSDOT manage traffic and relay traffic conditions to the public and media via WSDOT's website.
