Alternative C:
Roundabouts and Medians
Overview
Alternative C constructs a two-lane Kitsap Way with a single lane in each direction of travel and a raised center median. Alternative C also constructs multiple roundabouts along the corridor to improve the safety and efficiency of the roadway, while providing U-turn locations for local street and driveway access. Roundabouts will include crosswalks. Pedestrian and bicycle facilities include raised bike lanes on both sides of the street with either a shared use path or a sidewalk for pedestrians. In Kitsap Junction, parking aisles provide access to existing private parking.

Key Features: Alternative C
Raised Center Median
At Kitsap Junction, roundabouts slow traffic, and a raised center median eliminates conflicts with left-turning vehicles. Parking aisles allow access to existing private parking, and wide shared use paths are provided for pedestrians and cyclists. Roundabouts at Northlake Way or Harlow Drive allow U-turns to access the businesses on the other side of the street and provide left turns on the side streets.

Raised Center Median and Raised Bike Lanes
A raised center median along the corridor eliminates conflicts with left-turning vehicles. Drivers use roundabouts along the corridor to make U-turns for access to local streets and driveways on the opposite side of Kitsap Way. Raised bicycle lanes are provided in both directions separating cyclists from the shared use path and sidewalk areas.
