Upper Tokul Creek Bridge No. 271B Replacement Project
Project construction in progress until fall 2023
September 13, 2022
Our contractor is now onsite from 7 a.m. to 5 p.m. Monday through Friday. The first order of work is to remove trees and prepare the area for the temporary bridge. Removal and construction of the new bridge starts after the temporary bridge is installed. Total project construction will last approximately 10 months.

Upper Tokul Creek Bridge No. 271B provides sole access to approximately 50 single-family homes and is also used by nearby forest and mining industry vehicles. The bridge is located less than two miles north of Snoqualmie Falls where Tokul Road SE crosses Tokul Creek.
While safe for travel, the 57-year-old bridge is aging and requires frequent repairs. In addition, the current bridge is too narrow and has weight limit restrictions.
We will replace the old bridge with a new bridge that is 28 feet wide, have two 10-foot-wide travel lanes and two 4-foot wide shoulders. The bridge will be built primarily out of steel-reinforced concrete and built to current seismic standards. The new bridge will have no weight restrictions.
The bridge will remain open during construction
All vehicles will be diverted to a temporary one lane bridge located next to the active construction area. The temporary bridge will have no weight restrictions.
Tokul Creek during construction
Stage 1: Construct temporary bridge
Stage 2: Shift traffic to temporary bridge and demolish existing bridge
Stage 3: Construct new bridge
Stage 4: Shift traffic to new bridge and demolish temporary bridge
Bridge access for residents and emergency vehicles will be maintained throughout construction. Construction activities will include demolition, concrete pouring, and crane lifts. After the new bridge is opened to traffic, crews will remove the temporary bridge and continue with low impact restoration work including plantings and site clean-up.

The Road Services Division regularly inspects the bridges it is responsible for maintaining. If new restrictions are required based on these inspections, a notice will be posted on the bridge. We will also note any new restrictions on the Bridge Weight Restrictions website.
There will be no weight restrictions on the temporary detour bridge.
