From King County, Washington website:
When completed, the Foothills Trail will be 33 miles long, extending from the City of Puyallup, across the White River, ending near Kanaskat Palmer State Park.
The current project follows the abandoned historic Burlington Northern Santa Fe Railway line between Enumclaw and Buckley. It is anticipated that a future bridge will be constructed across the White River to connect the trail between King and Pierce counties.
