SR 20 - Sharpes Corner Vicinity - Interchange

Countdown to Construction
Project Facts
  • Skagit County traffic increased by 19 percent on state highways between 1996 and 2004 as the population grew by approximately 13,000 people.
  • On average, more than 30,000 vehicles pass through the Sharpes Corner intersection every day.
  • SR 20 is the primary means of delivering freight and goods to and from Whidbey Island.

Project Status

July 2008

  • We continue to refine the current roundabout design. We will hold another open house in Anacortes to update the community on our progress shortly.
  • We held a public meeting in Oak Harbor on Feb. 25. We displayed the results of the value engineering study and the original design options.
  • We completed the value engineering study in January. The group concluded that a modified roundabout is the best solution for the intersection.
  • Construction is scheduled to begin in 2011.

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

Project Benefits

  • Safety: Improvements to these intersections will increase traffic flow and decrease rear-end collisions, making the roadway safer for drivers.
  • 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?
We continue to plan and research this project. 
 
We anticipate construction beginning in 2011.

Public Involvement
Our formal comment period ended Jan. 4. You can still contact us with questions and comments. Contact Dave Chesson at 360-757-5970 or Dawn Yankauskas at 425-744-5103.

We will hold another open house in Anacortes this summer to update the community on this project.

We held a public meeting in Oak Harbor on Feb. 25. We displayed the results of the value engineering study and the original design options.

Nov. 15, 2008 - We hosted an open house in Anacortes on Nov. 15, to show the public six design options for improving the Sharpes Corner intersection, and to soliti comments from the public. We received over 175 comments.

If you can't make our open houses, please call or e-mail Dave Chesson, 360-757-5970 to get more details or submit comments.

Environmental Protection
WSDOT makes every effort to assess and minimize environmental impact from our projects. During project design, WSDOT will work to reduce the impact to wetlands, creeks and rivers in the project area. A detailed analysis of the project's environmental impacts will be completed and, if necessary, an appropriate plan for mitigation of impacts will be developed and documented as part of the Environmental Documentation and Environmental Permitting processes.

Please visit the WSDOT Environmental Services Web site for more information.

Increasing safety is one of our priorities
We will improve traffic flow and decrease the risk of collisions. Reducing congestion will reduce the risk of rear-end collsions.

During the construction phase of this project, WSDOT will implement all necessary traffic management and safety measures to ensure the safety of the traveling public, as well as our construction workers.

Will this project impact tribal resources?
We will consult with Tribes and other interested parties as we develop this project.  

At WSDOT we seek to address the concerns of the tribal nations using the process outlined in Section 106 of The National Historic Preservation Act and the WSDOT Tribal Consultation Policy adopted in 2003 by the Transportation Commission as part of the WSDOT Centennial Accord Plan.

To learn more about the tribal consultation process please visit WSDOT's Tribal Liaison page, where you'll find links to WSDOT Centennial Accord Plan and WSDOT's Tribal Consultation Policy (Adopted by the Transportation Commission on February 19, 2003).
