NE Stillwater Hill Road/Kelly Road NE Roadway Preservation Project

Project completed in Fall 2021

October 19, 2021 – Final centerline and fog line (white lines at edge of road) striping is complete. 

Overview

This project removed and replaced 1.59 miles of NE Stillwater Hill Road/Kelly Road NE, from State Route 203 to NE Big Rock Road located between Carnation, WA and Duvall, WA. Many travelers use this section of road as an alternate access route to SR 203 and to reach points east of NE Big Rock Road. The pavement and the support system under the pavement were in poor condition. Restoration of this well-traveled thoroughfare ensures its usefulness for years to come.

The work on this project included excavating, restoring, and repaving the roadway and shoulders from the ground up.

How we maintained access to residents during construction

Local access to residences, businesses, deliveries, and emergency services were maintained during the entire project. Road Services created a strategy to ensure access to residents, as this was a major pass-through route. To execute this strategy, we provided access points at the intersection of NE Big Rock Rd/Kelly Rd NE and SR 203/NE Stillwater Hill Rd.

The project was divided into four separate work zones: A, B, C, and D. Because work occurred in two adjacent work zones at a time, those with local access were directed to utilize one of the two access points. Flaggers remained on-site to direct traffic and assist drivers with access to their driveways.
