Fairfax Bridge Closure: What Hikers and Visitors Need to Know
Why Did WSDOT Close the Fairfax Bridge?
On April 14, 2025, the Washington State Department of Transportation (WSDOT) closed the SR 165 Fairfax Bridge due to structural concerns. A routine inspection revealed significant deterioration in the steel supports of the 103-year-old bridge, located just south of Carbonado. As a result, the bridge is closed to all public access—vehicles, pedestrians, and cyclists.
This bridge was the sole public route to Mowich Lake and the Carbon River Ranger Station from SR 165. Currently, there is no public detour available. A gated emergency road exists but is restricted to first responders and local property owners. WSDOT has initiated a study to explore replacement or rerouting options, but no construction funding is currently available.

Can I Still Camp at Ipsut Creek or Mowich Lake?
Yes—but only with a valid wilderness permit from Mount Rainier National Park. You’ll need to hike in via the Wonderland Trail from another section of the park, as vehicle access via SR 165 is closed. There is no parking near trailheads or campsites on the SR 165 side.
Please note:

No potable water is available—bring a water filter or treatment method.
-
Backpackers must be self-sufficient.
-
Search and rescue assistance isn’t guaranteed.
-
Mowich Lake restrooms will remain open for backpackers this summer.

Can I Hike In to See the Closed Bridge?
No. Although the closure has sparked curiosity, the area around the Fairfax Bridge is off-limits. You cannot reach it legally on foot, by bike, or by vehicle. Locals who live south of the bridge use a gated, unpaved logging road as a private emergency route. This road crosses private property and is not open to the public. Entering it without permission is trespassing. Please respect all closures and boundaries. This is both a safety issue and a community concern.
Is There a Backdoor Route via the Foothills Trail?
No. Despite some online claims, no legal route exists into the park from SR 165. Some believe they can access the park via the Foothills Trail or a mix of informal paths near Carbonado. This is inaccurate. There is no public access into the park via trails from Carbonado. Routes often cross private property. Visit Rainier and the National Park Service do not promote or condone trespassing to access Mount Rainier.
Is the Paul Peak Gate Open during the Fairfax Bridge Closure?
No. Not during the bridge closure.
Is the Carbon River Ranger Station Open?
Yes, but hours are intermittent and not guaranteed.
Are the businesses in Carbonado and Wilkeson Open?
