SR203 Safety Improvements
This project proposes to reconstruct the portion of State Route 203 (SR-203) between mile posts 13.9 and 14.6 (approximately 3700 linear feet) between Ring Street and Big Rock Road. The project consists of channelization and surfacing improvements and installation of bike lanes, curb, gutter & sidewalk on both sides of the roadway along with utility, lighting, and streetscape improvements. Overall, the project will complete a missing link on a vital corridor by creating a streetscape that is both inviting and safe for pedestrians, bicycles and vehicles.

Big improvements are coming to Duvall’s Main Street between Ring Street and Big Rock Road. After years of design, permitting, and preparation work; the Main Street South project is about to begin. Though officially titled the “SR 203 Safety Improvements and Road Reconstruction” project –Main Street South will make significant improvements to approximately 4,200 linear feet of SR 203.
The $8 million construction project will connect to existing improvements and build on the success of the 2009 downtown improvements, 2013 centennial project, and last year’s culvert and “bridge” construction at Coe Clemons Creek. With the addition of sidewalks, bike lanes, lighting, and the placement of utilities underground Main Street will receive a dramatic new appearance. A focal point at NE 143rd called “Rosenbach Corner” will provide a pedestrian refuge and observation points for a restored Thayer Creek.
After receiving 8 bids for the project in late July, Interwest Construction of Burlington, WA was awarded the contract. Construction is expected to begin in early September 2016, and with 300 working days allotted work is expected to be completed in early 2018. People travelling along Main Street should expect typical construction related traffic delays with single lane closures controlled by flaggers. Use of alternate routes is encouraged. A full road closure near NE 143rd Place will occur in the summer of 2017 for the installation of a culvert crossings for Thayer Creek.
Regular updates regarding the progress of this project, including road closures, will be posted to the City of Duvall’s Facebook page and official website. All project related questions or inquiries can be directed to the City’s Project Manager, Shaun Tozer either by phone at 425-788-3434 or email.
