February 2026
King County’s contractor is continuing construction activities in Bellevue.
On the early morning of Monday, February 23 and Tuesday, February 24, the contractor will stop traffic in both directions on Coal Creek Parkway SE for short durations. The closures will be just north of the Forest Drive SE and Coal Creek Parkway SE intersection and will occur intermittently between 2:30 am and 5 am.
These closures are required so the contractor can safely move oversized equipment in and out of the work area. Drivers should expect significant delays on Coal Creek Parkway SE during these hours. We encourage drivers to use alternate routes during the closure.
What to expect:
-
Traffic impacts: Expect traffic delays. City of Bellevue Police, lane closure controls and flaggers will help direct traffic. Drivers and cyclists will wait outside the road closure area until directed through.
-
Work hours: 2:30 a.m. to 5 a.m., Monday, Feb. 23 and Tuesday, Feb. 24.
-
Construction noise typical to a work site.
 Note: Road closure area shown on the map is approximate.
Ongoing daytime single-lane closures
The daytime northbound and southbound single-lane closures on Coal Creek Parkway SE will remain in place as construction activities continue. We will provide timely updates on any changes to the expected traffic impacts.
- Permitted work hours for the southbound single-lane closure are 6 am to 3 pm, Monday to Friday.
- Permitted work hours for the northbound single-lane closure are 10:30 am to 7:30 pm, Monday to Friday.
 Note: Lane closure areas shown on the map are approximate.
About this project
Construction for King County Wastewater Treatment Division's (WTD) Coal Creek Sewer Upgrade Project began in 2025. This project will provide needed wastewater capacity for growing communities in Bellevue and Newcastle.
After construction, the contractor will restore the Coal Creek Natural Area, parking areas, and affected roadways to protect the creek, trails, and infrastructure. The rebuilt Red Cedar Trailhead will keep the same look-and-feel while enhancing accessibility for visitors of all abilities.
