SR 20 - Sharpes Corner Vicinity - Interchange

Status

October 2009

  • The 2009 legislative budget has delayed this project. It will no longer go to construction in 2011. The project has been shelved, and design will resume when funding is again allocated to the project.

Overview
We will improve the Sharpes Corner intersection in Anacortes to relieve congestion and increase safety. We looked at six design options to improve the intersection. We completed a value engineering study that concluded that a modified roundabout would be the best solution to improve safety and relieve congestion at the intersection.

Why is WSDOT improving the Sharpes Corner intersection?
SR 20 is the only direct land access to the city of Oak Harbor, the Whidbey Island Naval Air Station, and the rest of Whidbey Island. The SR 20 spur is the primary access to Anacortes and ferry service to the San Juan Islands and Vancouver, BC. As a consequence, the intersection of these two roadways is of significant regional importance.

On average, more than 30,000 vehicles pass through the Sharpes Corner intersection every day creating heavy traffic congestion. Backups can be severe and increase the chance of collisions. Traffic turning west towards Whidbey Island often backs up beyond the turn lane, leaving vehicles stopped on the highway, increasing the chance of rear-end collisions.

We also need to incorporate any changes to the Sharpes Corner intersection to include Fidalgo Bay Road, where it connects at the intersection.

The End Result
When construction is complete, the intersections will move traffic in a faster, safer manner. We will pick the best option to relieve congestion and improve safety. 

We have heard from many of you that bike/pedestrian improvements are very important, and we are doing as much as we can to include improvements in our design. We have applied for a grant which would help us pay for a trail near the golf course.

Project Benefits

  • Safety: Improvements to these intersections will increase traffic flow and decrease rear-end collisions, making the roadway safer for drivers. Bicycle and pedestrian improvements will increase safety and mobility in the area.
  • Improve traffic flow: Drivers will see significant increases in roadway capacity and traffic flow. This means shorter drive times and less time sitting in traffic.
  • Environment: We will make improvements to stormwater culverts and detention ponds where necessary to meet current WSDOT environmental standards. 

What is the project timeline?
May, 2009 - The 2009 legislative budget has delayed this project indefinitely. It will no longer go to construction in 2011. The project has been shelved, and design will resume when funding is again allocated to the project.

Sept. 25, 2008 - We hosted another open house in Anacortes to update the community on our design progress to date.

Feb. 25, 2008 - We held an open house in Oak Harbor to update the community on plans to build a roundabout at Sharpes Corner.

Jan. 31, 2008 - The Value Engineering team chooses a modified roundabout as the best choice to improve the intersection.

Jan. 2008 - We held a Value Engineering study to evaluate all the options and look for ways to improve on the recommended option.

Nov. 15, 2007 - We hosted an open house in Anacortes to showcase six design options.

2005 - The Legislature provided funding to improve the intersection as part of the 2005 Transportation Partnership Program.
