Major repairs are needed to the historic Tokul Creek Trestle, a stunning, century-old wooden structure that once carried railroad cars and now serves as part of King County Parks’ Snoqualmie Valley Trail.

Soaring 120 feet above the creek and spanning a 400-foot-wide chasm, the trestle needs safety improvements, including new structural timbers and reinforcements, plus new concrete deck panels.

The work is expected to begin Sept. 15 and last into spring of 2016.

During this time, a three-mile-long stretch of the Snoqualmie Valley Trail will be closed to all access.

Because of the trestle’s remote location with no viable alternative routes, the trail will be from the trailhead at 356th Drive Southeast in Fall City to about one-quarter mile north of Tokul Road Southeast in Snoqualmie.

Funding for the trail repairs is provided by the 2014-19 King County Parks, Trails and Open Space Replacement Levy through the Bridge and Trestle Program.

At more than 31 miles in length, the Snoqualmie Valley Trail is the longest trail in King County Parks’ 185-mile regional trail system.
