Snohomish County, Washington Index-Galena Rd: MP 6.4-6.9 Repairs

Index-Galena Rd: MP 6.5-6.9 Repairs

Construction began in April 2021 to repair the final section of roadway that was heavily damaged during flood events in November 2006. Onsite project work is winding down for the winter and will resume in the spring of 2022. The area remains closed to the public through the end of construction and the project is anticipated to be completed in late 2023.  

This year crews completed some major milestones, which include: 

• Removal of old roadway debris is 95 percent complete including in-stream clean-up efforts.
• Land clearing involving tree and rock removal is complete. Approximately 250 trees were cleared and salvaged logs will be used for onsite habitat restoration and U.S. Forest Service habitat restoration located elsewhere in the Mt. Baker Snoqualmie National Forest.
• Earthwork including excavation and embankment for the new roadway is partially constructed.
• Construction of structural elements included:
  
  • A vented ford box culvert was completed. This armored culvert crosses through a historical rock debris slide area and conveys a stream underneath the road. It was built to be resilient against future sliding debris.
  • Four six-foot diameter drilled shafts were installed to depths between 70 and 110 feet in the ground to support the future 180-foot bridge near mile post 6.9.
