SR 20 - Banta Rd - Intersection Safety Improvements - Complete Sept. 2019

Overview

In 2019, The Washington State Department of Transportation built a roundabout at State Route 20 and Banta Road/Northgate Drive on Whidbeby Island. 

Improving safety on state highways is a top priority for WSDOT. Since 2011, law enforcement responded to 26 crashes at this intersection. Eleven of those collisions involved injuries. Statistics show that roundabouts help reduce injury and deadly crashes by more than 75 percent. This roundabout project will help improve safety during peak congestion and keep drivers moving through this area.

Island Transit also services stops on each side of the highway, the new roundabout includes pedestrian crossing areas and islands to help people safely cross the highway when accessing the nearby bus stops.

This roundabout also allows drivers north and south of the intersection to choose right-in right-out options from other intersections and driveways by providing a U-turn option at the new roundabout and will:

  • Reduce the number of injury crashes, supporting Washington's strategic highway Target Zero plan.
  • Keep drivers moving as additional vehicles are added to the road in this area.

Funding

The total estimated cost of this project was $3.2 million.
