Cedar River Trail is back January 29, 2009 2:57 am King County crews spent the past week rebuilding a section of the Cedar River Trail that was washed out by flooding this month. The segment had to be closed between 196th Avenue Southeast and Southeast Cedar Grove Road until repairs were finished. The latest woes happened about four months after part of the trail was closed for six weeks last summer for repairs of damage from the November 2006 flood.
