History
From 2012 to 2015, the Washington State Department of Transportation and Plug-In North Central Washington built 32 charging stations at popular destinations along the Cascade Loop, spaced 25 to 50 mi apart, to serve electric vehicles. Additional charging stations belonging to city governments, businesses and homeowners were added to the byway's list of electric charging stations in 2017.

The Cascade Loop was designated as a National Scenic Byway on January 19, 2021.
