The Bainbridge Island City Council will get a briefing from state officials at possible improvements to Highway 305 — which include three roundabouts on Bainbridge — at its meeting this week.

Last week, Steve Roark, assistant region administrator for the Washington Department of Transportation, briefed the Poulsbo City Council on still-developing plans for safety and mobility improvements along a roughly 11-mile stretch of Highway 305.

Bainbridge council members will get a similar briefing at their study session on Tuesday, July 17.

The meeting starts at 7 p.m.

Three roundabouts are in the plans for Bainbridge Island on Highway 305: at Day Road, Ada’s Will Lane and NE Port Madison Road. Improvements between the ferry terminal and Hostmark Street in Poulsbo will be financed by $36.8 million that was set aside for Highway 305 as part of the “Connection WA Act,” approved by the Legislature in 2015.

Here are the conceptual drawings of the new roundabouts that are being examined, starting with the three on Bainbridge, followed by the roundabouts on the west side of the Agate Pass Bridge.
