SE Edgewick Road Slide Repair Project
Permanent repairs began on February 16, 2026
February 17, 2026: Crews have begun permanent construction to repair the slide on SE Edgewick Road.
Status update
February 18, 2026
Construction to repair the slide on SE Edgewick Road began on Monday, February 16, 2026. The road is closed to all traffic including vehicles, pedestrians, and bicycles during construction. We anticipate that the repairs will take six weeks. The project could be delayed due to crew, material, or equipment availability or weather.
Thanks to an agreement from the Parks Division, the Snoqualmie Valley Trail can be used as an Alternative Route for essential trips in and out of the neighborhood and for emergency responders. The trail is closed to pedestrians and bicycles while it is being used as an alternative route. Please use caution at all times while driving on the trail and do not take shortcuts. Please read below for the map and more information.

A community meeting was held on February 10, 2026. You can view the slide deck here (5.5 MB).
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 are cutting into the hillside. This will include adding 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: December 2025 to February 15th
- Crews reinforced the ditch at the slide location and added additional drainage.
- This 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: Began on February 16th
- Crews began permanent repairs to the roadway on February 16, 2026. We expect construction on this phase to take up to six weeks.
- SE Edgewick Road is closed to all traffic and the Alternative Route via the Snoqualmie Valley Trail is reinstated. A temporary bridge was added over the existing private bridge allowing emergency services to enter the neighborhood. The temporary bridge does not have any weight limit restrictions.
- 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.
Alternative route
In partnership with the King County Parks Division, Road Services identified an alternative route for residents to use while SE Edgewick Road is closed due to slide activity. View larger (4MB)
Recent heavy rains and flooding resulted in damage to SE Edgewick Road, effectively cutting off vehicle access to homes of some local residents. Road Services in partnership with the Parks Division, is expediting repairs and providing alternative access for those affected homeowners.
A plan was developed to convert a portion of the Snoqualmie Valley Trail to a temporary access route between Cedar Falls Road SE and 44670 SE Edgewick Road. This portion of the trail will be temporarily closed to pedestrian and bicycle users to facilitate safer conditions for vehicle traffic.
However, please be aware that the Alternative Route is not a King County public road, is not constructed to King County public road standards, is not maintained or patrolled by King County, and does not have safety features often associated with county roads, such as guard rails, regular signage, lighting or shoulders. The Alternative Route is primitive in nature and is not suitable for use by all vehicles, particularly larger ones. The road surface is gravel and dirt with uneven surfaces, potholes or other deformities, and is at times very narrow with limited to no shoulder. In the event of an emergency or breakdown, it will potentially take a long time for responders to arrive. If you elect to use the Alternative Route, then in addition to driving with standard care and attention, the following safety practices are strongly encouraged:
- Limit use of trail to cars and light trucks
- No trailers are allowed
- No flammable materials are allowed
- Keep speed under 10 MPH
- Drive with headlights on at all times
- Be alert for other traffic on the trail, and be prepared to back up for long distances to accommodate passing oncoming vehicles.
- Do not stop on the trail
- Large animals are allowed on the trail
- Follow the signed detour route
- If you have an emergency, call 911
Because this Alternative Route was not originally designed for vehicles, any use of this trail may result in damage or deterioration of the trail to the point of it no longer being available for vehicle traffic. Please limit trips to a minimum, and to smaller, lighter vehicles so as to maximize the length of time this option is available for use to you and your neighbors.
If there is any damage or deterioration of the trail that needs our immediate attention, please contact King County Parks Division at 206-477-4527.

Frequently asked questions
The Parks Division placed signs that indicate that delivery trucks and vans cannot use the road. We’ve been in contact with USPS to let them know of the closure. They should be holding your mail and packages, but it is always a good idea to talk with them directly.
Yes, the new temporary bridge does not have any weight limit restrictions and emergency responders can access your community using the Snoqualmie Valley trail. Road Services is in regular communication with Eastside Fire & Rescue.
Our team is also in conversation with the County Fire Marshal to ensure they are aware of these constraints.

February 7, 2026: Crews added a temporary bridge over the existing private bridge along the alternative route. The temporary bridge does not have any weight limit restrictions and allows for emergency responders to access the Edgewick neighborhood during construction.
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.
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.
