Project Update

Posted Oct. 2, 2026: Lots of calls and questions this week from people asking if Beaver Hill is actually closed. We completed our first week of a full closure -- no vehicles are allowed, or able, to go through the work zone. The contractor completed sawcut and road excavation this week and hopes to begin construction on the new retaining wall the week of Oct. 5. Other traffic impacts occurring the week of Oct. 5 in the Chumstick/US 2 area:

  • Our Leavenworth crew has one more driveway culvert to install on Chumstick Highway between Merry Canyon Road and Little Chumstick Road. Watch for one-lane, flagger-controlled traffic. Traffic delays will be minor on this county project. Our county road crew also will be doing some maintainence work on Chumstick Highway this week.
  • A WSDOT contractor is making road repairs to Chumstick Highway that are related to the December storm. Contact WSDOT for any updates.
  • WSDOT and Chelan PUD also are working on US 2 in the Tumwater Canyon. Contact those agencies for any updates.

 

Chumstick Highway at Beaver Hill near Plain will be closed for about three weeks beginning Sept. 28 so a Chelan County Public Works contractor can build a retaining wall at the site of a landslide that occurred this past winter.

This will be done under a full road closure, meaning motorists will not be able to get through the work zone. Detour routes are on either side of the closure.

The work was originally scheduled to begin in August; however, the start date was pushed back out of concerns for the ongoing Little Giant Fire.

In 2016, Chelan County built a retaining wall on Beaver Hill to stabilize the slope next to the roadway. The wall stood up well during the December 2025 weather event that caused much flooding in the northern part of Chelan County. However, a slide occurred just past the wall, causing Beaver Hill to be temporarily closed.

In addition to extending the existing retaining wall by 150 feet, other nearby slopes will be repaired and stabilized with additional fill and new guardrail.

The project area is from milepost 12.3 to 12.4 on Chumstick Highway. The speed limit will be lowered to 25 mph about a mile before the project area, on each side of the closure.

The $790,000 project is paid for with a mix of federal emergency relief funds and county road funds.
