Travelers and locals are facing an indefinite closure of the State Route 165 Carbon River Fairfax Bridge. Washington State Department of Transportation shut it down due to safety concerns. The bridge, built in 1921, is three miles south of Carbonado at milepost 11.5. Recent inspections found serious damage to its steel supports, making it unsafe for cars or pedestrians.
An immediate closure was deemed necessary to ensure public safety, with further analysis to be undertaken by Washington State Department of Transportation bridge engineers in the weeks ahead. The full extent of the bridge's deterioration will only be known once their assessment is complete. This sudden suspension of access disrupts the only route to popular destinations such as Mount Rainier National Park's Mowich Lake Entrance and the Carbon River Ranger Station. According to a statement released by the Washington State Department of Transportation, an emergency detour route established in 2024 for first responders and local property owners remains unavailable to the public.
The Fairfax Bridge's story reflects a bigger issue—aging infrastructure lasting longer than planned. Built over 103 years ago to last about 75 years, it has outlived its expected lifespan. On average, state-owned bridges in Washington are 51 years old. Over the years, the Carbon River Bridge faced more and more limits, including a weight limit reduced to 16,000 pounds in July 2024, as detailed by the Washington State Department of Transportation.
As the area adjusts to the closure, Washington State Department of Transportation is working to keep an eye on the state’s 3,600 bridges—a big job highlighted by the issues with the Fairfax Bridge.
