Repair work on the Tolt Hill Bridge 1834A is scheduled to begin Monday, April 23. Set-up, including the staging of equipment and materials, begins Thursday, April 19. The repair work includes retrofitting truss joints, replacing bolts with higher strength bolts, and adding new bolts and splice plates. During construction, beginning April 23, one lane will be open for motorists to cross the bridge. A signal will be set up to alternate the direction of traffic across the bridge. The signal will be in place 24/7 while work is being performed. A one-week full closure of the bridge will occur during the summer. The exact dates of the full closure have yet to be determined. The public will be provided with notification two weeks prior to the full closure. The repair work is expected to finish this fall. The current six-ton load restriction will remain in place during construction. Once the repair work is complete, the weight restriction on the bridge will be lifted.

March 12, 2018 - Update
A construction contract for repair work has been executed. Garco Construction will perform the work which is anticipated to begin this spring and last approximately six months. During construction one lane will be open for motorists to cross the bridge. A signal will be set up to alternate the direction of traffic across the bridge. This will be in place 24/7 while the work is being performed. In addition, a one week full closure of the bridge will occur during the summer. Garco Construction will provide a schedule which we will post on this webpage. Please check back for updates.

Nov. 14, , 2017 - Update
On Monday, Nov. 20, between 9 a.m. - 1:30 p.m., King County is coordinating with the Washington State Department of Transportation to utilize an Under Bridge Inspection Truck to perform a four-hour inspection of the joint connection details of the steel trusses on the Tolt Bridge. The information from this inspection will be utilized in the final design effort for the bridge’s repair. This work requires lane restrictions. Traffic will be flagged through the work zone.

Oct. 3, 2017 - Update
Engineers are working towards having a bridge repair design completed by the end of this year. Construction is anticipated to begin in early 2018, although a schedule has not yet been set. We will continue to update this page as we receive more details. Please consider signing up for Road Alert emails and texts to receive the latest information. To sign-up, click HERE.

July 17, 2017 - Update
The Tolt Hill Bridge is scheduled to reopen at 1 p.m. on Monday, July 17 with restrictions. Engineers have determined it is safe to allow traffic on the bridge where each vehicle is six tons or less fully loaded. Bikes and pedestrians are also allowed.

July 14, 2017 - Update
Engineers have completed an in-depth analysis of the loads the Tolt Hill Bridge can safely carry. They have determined it is safe to allow traffic on the bridge where each vehicle is six tons or less. For example, a fully loaded pickup truck would be less than six tons. Load restriction signs will be posted on the bridge. Future closures for repairs are likely, but not yet determined.

On Monday, July 17, when new signage is available and can be deployed, the Tolt Hill Bridge will reopen to noncommercial pickup trucks, passenger vehicles, bikes and pedestrians.

Bridge repairs still need to take place, and will likely result in some future closures. More information on repair efforts and related closures will be available when design experts determine the best approach to repairs. We will continue to keep you updated on this webpage and through the email and text alert system. To sign up for the alert system, click the red “Stay connected” button on the right side of this webpage. Updates will include progress of the repair design, the repair schedule once determined, and potential traffic impacts to motorists during construction.

July 11, 2017 - Closure update
From Saturday, July 15 at 6 a.m. to Monday, July 17 at 5 a.m., a second phase of road resurfacing work will take place on NE Novelty Hill Road from 243rd Avenue NE to West Snoqualmie Valley Road NE. This work is a continuation of last weekend’s road resurfacing project (July 7-10) and requires a full weekend closure. This route is listed as a detour option for motorists impacted by the Tolt Hill Bridge closure. Emergency service vehicles will be able to use this section of NE Novelty Hill Road during the July 15-17 closure. Click HERE to see the map.

July 7, 2017 - Closure update
The county is consulting with the Washington State Department of Transportation bridge experts, the Federal Highway Administration and a design engineering firm to discuss next steps for the bridge, including whether or not the bridge can be safely reopened to limited traffic. The county’s consultant design engineering firm is developing a repair design, reviewing the new federal methodology for determining the load a bridge can carry, and will work with a design expert who specializes in this type of bridge (steel truss design). A contractor will also be hired to provide a review of the project design. As soon as we know more about the repair plan and load rating results, we will post an update on this page and send out a Road Alert email and text. To sign-up for Road Alerts, click HERE..

June 30, 2017 - Full weekend closure on part of NE Novelty Hill Road, July 7-10
Beginning Friday, July 7 at 7 p.m., crews will begin road resurfacing work on NE Novelty Hill Road from 243rd Avenue NE to West Snoqualmie Valley Road NE. This work will require a full weekend closure. Emergency service vehicles will be able to use the road during the closure. The work is expected to finish at 5 a.m. on Monday, July 10. This closure will not impact any of the river crossings/bridges in the Snoqualmie Valley area. Agencies are coordinating their upcoming road work schedules to keep impacts at a minimum.
