SR 522 Stage 1
The purpose of the project was to relieve congestion on SR 522 at the 96th Avenue NE intersection. The addition of transit queue lanes in each direction allows mass transit to bypass the traffic signals in the westbound direction or have signal priority in the eastbound direction at 96th Ave. NE after King County Metro installed its transit signal priority system. Other work in this section included installation of center medians; asphalt and concrete paving, a new gateway sign, and improvements in the Red Brick Road Park area. This project was funded by the City, Sound Transit, Washington State Department of Transportation, the State Transportation Improvement Board (state gas tax), Federal Highway Administration and King County. The project also received the Urban Vitality grant through the State Public Works Board, which administers Washington State taxpayer funds.
