March 2016 Update

In the past year, Snohomish County Public Works has evaluated modifying the roadway alignment to reduce the cost of the project, including reducing the amount of proposed retaining walls and overall project footprint. The county is expecting to be in the design, permitting, and environmental review process through 2017. Construction is estimated to begin on the final segment of Index Galena Road in the spring of 2018.

Agency Review Process
Snohomish County Public Works submitted a draft Biological Assessment (BA) for the proposed repairs to Index-Galena Road. This assessment is part of an extensive environmental review process to help ensure protection of Endangered Species Act (ESA) listed species including fish, birds and amphibians.

Due to Index-Galena Road’s location on United States Forest Service (USFS) land and the proposed relocation of the road, this project has required extensive interagency coordination with multiple federal, tribal, state and county government agencies. Over a period of 12 months, the National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (USFW) will be reviewing the BA in consultant with the ESA. Once completed, these documents will be uploaded to Snohomish County’s Index-Galena Road webpage for public viewing.
The extensive environmental review process is outlined and explained in this document (pdf).

Snohomish County Public Works has repaired 10 of the 11 originally damaged areas from the 2006 heavy rains that severely impaired Index-Galena Road. Currently, Milepost 6.4 to 6.9 is the only area left to repair and remains closed to traffic. This portion of road was considered a total loss with significant portions of pavement, road bed, and culverts damaged by the flooding. Repair work has also been completed at the recently damaged Milepost 3.0 on Index-Galena road. Paving and finishing work is expected to be completed at Milepost 3.0 in the summer of 2016.

Traffic impacts

Index-Galena Road was damaged by additional river flooding in November 2015. Local access is restricted to one lane past Milepost 3. Access is available from the east end of Index-Galena Road, via US 2 to Beckler River Road to Jack's Pass, and to milepost 6.9.

From the east the road opens to National Forest lands for general recreation, camping and mineral claims along the North Fork Skykomish, Salmon Creek and Silver Creek drainage basins. Troublesome Creek and San Juan Campground are also accessible from the east. The Forest Service has a gate on the Forest Service road past Troublesome Creek.

Jack Pass Maintenance
Snohomish County is in a ten year agreement with the USFS to help maintain Beckler River Road which includes the road through Jack Pass. Both agencies meet annually to discuss repairs and maintenance needed to keep the road in working condition. The road through Jack Pass will remain unplowed and closed during the winter months. While seasonal conditions vary from year to year, the pass typically is open to use in late May through early November.
