The current culvert at the Mount Massive Trailhead has caused the channel to over-widen at the outflow of the culvert. It prevents fish passage, limiting upstream migration to publicly accessible waters. Replacement of the culvert will improve stream health by creating a natural stream bottom, increasing floodplain connectivity, and allowing for aquatic organism passage. The USFS has identified a more suitable location for placement of a stream crossing approximately 200 yards downstream of the current culvert. This project will install a box culvert in this new location, providing a better experience for the public traveling on the road and to the trailhead. The previous culvert location will be restored.
Replacement is scheduled for fall of 2025.
