Puget Sound Energy is working on upgrading parts of the power lines through the area. This will cause a section of trail between the East Puyallup Trailhead and N 96th St E in Puyallup. Planned closure is from August 1 through October 31, 2017. There will be a temporary parking lot located near N 96th St E during this time.
The map below shows closed section and temporary parking area. (This is from the information we know.)
