- Drivers should plane for single-lane and shoulder closures on SR 20 between 7 a.m. and 4 p.m. Mondays through Thursdays.
- Construction began on June 13.
- WSDOT completed the environmental documentation process on Oct. 30, 2014.
- This project was awarded to Interwest Construction, Inc.
- Sign up for email updates about this project and other state roadwork in Island and Skagit counties.
We will add a two-way left-turn lane on State Route 20 at Island County's Solid Waste facility just south of Coupeville. We also will widen the shoulders of the highway to four feet wide between Jacobs Road and the solid waste facility, and make other safety improvements.
- We will realign Parker Road to connect with Morris Road, eliminating the intersection of Parker and SR 20. Vehicles will use Morris Road as the connector between SR 20 and Parker Road.
- The intersection of Smith Prairie Road and SR 20 will be closed.
- For vehicles turning onto Morris Road, a left-turn lane will be added to southbound SR 20 and a right-turn only lane will be added to northbound SR 20.
- For vehicles turning left from Morris Road to southbound SR 20, a short center merge lane will be added to the highway.
Why is WSDOT
adding a left-turn lane on SR 20 at the Solid Waste Complex and designing changes to the Parker/Morris road intersection?
A high rate of rear-end collisions related to vehicles turning in and out of the Solid Waste Complex have occurred. This will help reduce the frequency and severity of these collisions between Morris Road and Jacobs Road.
Community members and local elected officials expressed safety concerns regarding the Parker and Morris roads intersections with SR 20. We identified several possible solutions to improve this area and hosted an open house in December 2012. In February 2013 WSDOT chose the alternative that realigns Parker Road to intersect with Morris Road and makes improvements to the Morris Road intersection with SR 20.
What challenges are we facing with these changes?
- Project timing: Adding a left turn lane to SR 20 and realigning Parker Road must be done during the summer because paving the new lane and realigned road requires warm, dry weather.
- Coordinating with other projects: WSDOT has a paving project on SR 20 between Frostad Road and Sharpes Corner. By working on the Morris Road to Jacobs Road project during the day and the Frostad Road to Sharpes Corner project at night, drivers are not likely to encounter lane closures at both on the same trip.
- Environmental mitigation: The project is located in the Ebey’s Landing National Historical Reserve. Because of this, the new Parker Road alignment must match the natural contour of the land. The project will include two 35-foot tall lights at the transfer station and two at SR 20 and Morris Road. The light poles will be painted brown to reduce their visual impact and have hoods to limit lighting to the intersection area. WSDOT will install weatherized steel guard rail. Without the guard rail, more trees would need to be removed for safety. Using 11-foot lanes and four-foot shoulders will minimize the impact on the surrounding land.
- Moving utilities: Utility companies need to move power, telephone, cable and fiber optic lines before WSDOT begins its safety improvement work. This may require short-term single lane closures along SR 20.
What should drivers expect?
The intersection of Smith Prairie Road and SR 20 will be closed. The current Parker Road will remain open until the realigned Parker Road is complete. Construction will take place during the day with single lane closures. Driver should expect some delays and flaggers controlling traffic through the work zones.
The End Result
Adding a turn lane will help improve safety and reduce the number of collisions for drivers turning in and out of the Solid Waste Complex. Because the project is located within the Ebey's Landing National Historical Reserve, we are designing it in such a way as to minimize and mitigate impacts to the reserve. Closing the SR 20/Smith Prairie Road intersection eliminates the collision risk. Eliminating the Parker Road/SR 20 intersection and moving Parker Road to intersection with Morris Road will improve safety and reduce collisions as well.
- Installing a turn lane adjacent to the Solid Waste Complex and the shoulder-widening will reduce the frequency and severity of collisions.
- Closing the SR 20/Smith Prairie Road and SR 20/Parker Road intersections eliminates the potential for collisions.
- Improvements to the SR 20 and Parker/Morris roads intersections will help reduce the opportunity for collisions.
