A full closure of S.R. 203, at the intersection of Duvall’s NE 143rd Place will begin Monday July 17, as contractors complete another phase in the city’s improvements to Main Street.

The closure, expected to last until 4 p.m. Wednesday July 26, will be needed to replace a culvert at Thayer Creek.

During the work, contractor Interwest Construction will relocate utilities, set 28 sections of culvert and rebuild the road. It’s expected to take 1,300 man-hours to complete.

“Fortunately, we’ve experienced this type of work before,” said Public Works Director, Boyd Benson, referring to the 2015 culvert replacement at Coe Clemons Creek.

Two detours will be set-up for the July work, at NE 124th Street to divert large trucks and commercial vehicle traffic around the city, and at Woodinville-Duvall Road, to allow passenger vehicle traffic into Duvall and up to the work zone with a short detour through city streets.

“It is of vital importance to our business community that the public knows Duvall is still open for business” said Mayor Will Ibershof.

The Thayer Creek culvert replacement is part of an $8 million improvement project along Duvall’s Main Street that began construction in September, 2016. Once completed; sidewalks, bike lanes and lighting will connect all of the businesses that have developed along the corridor.

Regular updates regarding the progress of this project will be posted to the city of Duvall’s Facebook and Twitter pages as well as a Thayer Creek page on the city’s website.
