Beginning summer 2021, WSDOT will build a key project for the SR 305 corridor on Bainbridge Island. Crews will begin construction of two modern roundabouts. One will be located at the intersection of Northeast West Port Madison while the second will be constructed at Northeast Adas Will Lane.

The following are design visualizations of the proposed roundabout at Northeast Port Madison Road.
