SE Edgewick Road Slide Repair Project
Permanent repairs are anticipated to begin in early 2026
January 7, 2026: Two-way traffic can now use a single lane of SE Edgewick Road. The road is very narrow (9.5 ft wide) with a 10-ton weight limit restriction. Please use extreme caution when using the road, especially in the dark.
Status update
Phase one of repairs on SE Edgewick Road are complete, and the road is currently open to two-way traffic through a single open lane. Please remember that the road is very narrow (9.5 ft wide) and is load limited to 10 tons. We urge you to drive extremely slowly and cautiously on the road, especially in the dark. The Alternative Route via the Snoqualmie Valley Trail is closed to vehicles.
We have alerted Eastside Fire & Rescue and US Mail that the road is open with restrictions. Eastside Fire will be able to continue life safety evacuation using an ATV or brush truck and their response times will improve with the open road; however, their fire trucks cannot get through the narrow and load limited road. Please use extreme caution if you are using a wood stove or fire recreationally or to heat your home. Please keep this in mind if you are using portable space heaters that can be fire hazards. Learn more about fire safety here. Our team is also in conversation with the County Fire Marshal to ensure they are aware of these constraints.
You are encouraged to reach out to service providers such as hay, septic, or propane and request deliveries. Please make sure that they understand the restrictions on the road.
This project could experience delays due to materials, crew, or equipment availability and is highly weather dependent.

Project overview
Crews identified that water could damage SE Edgewick Road, and in 2009 perforated pipes were installed to drain water away from the downslope. We believe that over time, one of those pipes shifted and allowed water to seep under the road. The amount of water during the December 2025 storm was unprecedented and the drainage system could not keep up.
To repair the road, crews will cut into the hillside. This may include rock to reinforce the road and fix the slide. The team will also install drainage improvements to reduce the risk of future slides.
What to expect during construction
We anticipate two phases of construction to repair SE Edgewick Road:
Phase 1:
- Crews reinforced the ditch at the slide location and added additional drainage.
- This will allowed our team to open a narrow 9.5-foot wide one lane roadway with a 10-ton weight limit.
- The alternative route via the Snoqualmie Valley Trail has closed to vehicular traffic.
Phase 2:
- Once the soil is drier, crews will return for permanent repairs to the roadway. We expect construction on this phase to take three to four weeks.
- During these repairs, we will need to fully close SE Edgewick Road to all traffic and the Alternative Route via the Snoqualmie Valley Trail will be reinstated. The weight limit on the private bridge will remain 5-tons.
- Crews will work during daylight hours and neighbors can expect the following during work:
- Noise and odor from saw cutting, jackhammers, excavators, generators and pumps.
- Increased truck traffic for hauling materials to and from the construction site.
Once phase 2 is complete, SE Edgewick Road will reopen to all two-way traffic without weight restrictions.
Frequently asked questions
Our crews are stretched very thin to keep up with the storm systems in our region. Our crews have been working in shifts around the clock to monitor our 1,500 miles of roads and 192 bridges and also assisting other divisions to prevent and repair levee breeches.
Our team prioritizes opening roads with the following characteristics:
- Lifeline emergency routes, routes to hospitals and other emergency services
- High-volume arterial roads that provide regional connections between communities and main highways
- Transit routes
- Sole access roads
Once they begin, we expect the project to take about three to four weeks to complete.

December 30, 2025: The private bridge at 44660 SE Edgewick Road now has a new, lower posted weight limit restriction of 5 tons.
December 18, 2025: The Snoqualmie Valley Trail is closed to pedestrians and bicyclists so that it can be used as an alternative route for the SE Edgewick Road community. The Parks Division placed signs to show that delivery vehicles are not allowed to use the trail. We need to limit use of this alternative route so that the trail is preserved as much as possible.
December 13, 2025: more water from the atmospheric river caused the hillside above SE Edgewick to slide. This slide is slightly uphill from the road damage.
On December 11, 2025, crews added compacted gravel to the road shoulder to create a narrow one lane on SE Edgewick Road with a 5-ton limit on vehicle weight. Shortly after, additional water forced this option to be closed.
On December 9, 2025, the ground underneath SE Edgewick Road slid during a rainstorm.
