The trail will be built on an old Burlington Northern Santa Fe railroad bed, stretching 4 miles from downtown Enumclaw to North River Avenue in Buckley. The trail will then connect to Pierce County's Foothills Trail, which is currently under construction. The Foothills Trail will run 23 miles between Puyallup and Buckley. The Enumclaw trail will require a bridge across the White River. Plans for the trail also include a 4-mile loop to connect the trail to the King County Fairgrounds.
Work includes adding new traffic lights and turn lanes to the on-ramps.
The purpose of the project is to ease traffic flow resulting from Costco customers flocking to its nearby store at 1725 S. Burlington Blvd. The city may repay Costco for some of the work, pending completion of a study that will show how others are benefiting from the project. The contractor expects to complete the work by late July. Eastmont School District No. 206 issued a determination of non-significance for a proposal to build a new junior high school. Preparatory work includes excavation and grading.
