Iron Mountain Sanitary Sewer & Pedestrian Bridge
The Iron Mountain Sanitary Sewer Bridge carries a wastewater transmission line through Tryon Creek State Park. The bridge is nearing the end of its useful life and needs rehabilitation or replacement. The Oregon State Parks Department may be willing to contribute up to $50,000 towards the project as the bridge also carries pedestrian traffic for park visitors. The bridge needs repair to remain open to pedestrian traffic.

The Iron Mountain Bridge will be closing for construction beginning August 15th and will remain closed until completion in November. The Iron Mountain Trail will be closed from the trailhead at Terwilliger to the south end of the Iron Mountain Bridge (intersection of the South Creek Trail and Iron Mountain Trail).
Construction will include rehabilitation of the sanitary sewer main attached to the bridge. The concrete main will be replaced by a joint less high density polyethylene line in a steel casing.
