The Cedar River Trail was washed out during recent heavy rains, and crews will be out working with heavy machinery to finish repairs and paving. So the trail will be closed for 4.5 miles from 154th Pl SE east to Cedar Grove RD SE until Monday (March 2).
There’s no official detour, but SR-169 does have a shoulder for most of this stretch. Obviously, that’s not nearly as comfortable as a trail, and you need to be especially careful at intersections.
More details from King County Parks:
Trail closed from 154th Pl SE to Cedar Grove Rd SE
Excessive rain and flooding washed out a portion of the trail. While repairs to the embankment and trail subsurface have been completed, the Cedar River Trail will remain closed at 154th Pl SE east to Cedar Grove RD SE until Monday, March 2, so that resurfacing and paving can be completed.
Heavy machinery will be on the trail along with spotters for safety. No formal detour will be available.
