Status

Project Complete September 2009

 

This Highway Capital Preservation Program project stabilized the slope above US 97 at Milepost 174.6, ten miles north of Blewett Pass and ten miles south of the Big Y junction with US 2 in Chelan County.

Why is WSDOT stabilizing this slope?
This hazardous rock slope was identified for stabilization in the WSDOT Unstable Slope Management Program (pdf).  Our Geotechnical staff evaluate such factors as catchment area, frequency of slope failures (rock fall incidents), and how often the driving lanes were impeded.

The End Result
is improved safety by reducing the potential for loose rocks to fall onto the roadway.

Project Benefits

  • Safety - Stability of this rock slope has been increased, providing safer driving conditions on US 97.
  • Economic -Less rockfall clean up and fewer pavement repairs reduces maintenance costs.

What is the project timeline?
Construction began July 27 and was complete September 18, 2009. (30 working days)
