SR 20 - Banta Rd - Intersection Safety Improvements

Project news

  • The new roundabout at SR 20 and Banta Road/Northgate Drive is open to traffic.
  • Temporary striping is currently in place. Crews plan to put down permanent striping, that will include strips with bumps and larger lane arrows, in early August.
  • People traveling SR 20 between Anacortes and Oak Harbor also should plan for overnight traffic delays over Deception Pass and Canoe Pass bridges.
  • You can sign up for weekly email updates about this and other Island County construction projects.

Overview:
This roundabout project will help improve safety during peak congestion and keep drivers moving through this area.

Needs & benefits

Why is WSDOT making safety improvements to this intersection?
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.

Island Transit also services stops on each side of the highway, the current intersection does not include safe pedestrian access across SR 20 for those using public transit. A roundabout will include pedestrian crossing areas and safe islands to help people safely cross the highway when accessing the nearby bus stops.

This roundabout will also allow 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.

The End Result
When this project is finished it will improve safety and keep drivers moving as traffic volumes in this area increase.

Project Benefits
Building a roundabout at this intersection will:

  • Reduce crashes.
  • 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.
