SR 305/West Port Madison, Agatewood Rd, Adas Will Ln – Safety Improvements

From 8 p.m. Monday, Oct. 7 to 6 a.m. Tuesday, Oct. 8, travelers can expect to see intermittent traffic stops of five minutes or less. From 8 p.m. Tuesday, Oct. 8 through Friday, Oct. 11 to 6 a.m. each following morning, travelers will see one-way alternating traffic on SR 305. During this time, contractor crews will prepare the roadway and then put down permanent roadway markings. This work is weather-dependent and could be rescheduled.

Project overview

WSDOT will build two modern roundabouts on Bainbridge Island at the intersections of SR 305 and Northeast West Port Madison and SR 305 and Northeast Adas Will Lane. The improvements include a feature at the intersection of Agatewood Road Northeast which will become a right in/right out intersection. This feature reduces the potential for collisions as a right in/right out eliminates left turns in front of oncoming traffic.

What to expect

Travelers may see intermittent traffic holds to allow trucks to enter and exit the highway. Traffic is typically held for one minute or less.

The roundabouts at both Adas Will Lane and West Port Madison/Seabold Road are operational. In August, crews will complete remaining drainage and electrical work and place the island at Agatewood Road. Final paving is currently scheduled for early September, with final striping to follow in early October.
