Blue Slough Road is used primarily as a route between Cosmopolis and Montesano. It has been used heavily on multiple occasions whenever there are blockages on US 12 between Aberdeen and Montesano.

The project location included a set of three horseshoe shaped curves with posted speeds of 25-35 MPH which presented difficult driving conditions for the public.

This section of roadway was realigned and widened. The new alignment was made up of one gentle curve. The new roadway was widened by 10 feet to an overall width, including shoulders, of 34 feet.
