US 97 - Blewett Pass Culverts Replacement - Project photos

The 5 mile Creek culvert is too small to carry current runoff

This undersized culvert for 5 mile Creek is one that was replaced with a larger structure to accommodate higher runoff volumes that have washed out roadway sections in the recent past.

In 2011 Blewett Pass was closed when the road washed out

The washout in January of 2011 happened when culverts were overwhelmed by record runoff

This culvert near the Swauk Creek campground is a barrier to salmon

This culvert on the south side of the summit has been a barrier to salmon and trout.
