About this file
This document is an Oregon Department of Transportation bridge inspection report for the Little Luckiamute Creek Bridge. The report provides details on the condition of the various bridge elements, noting corrosion, damage, and deficiencies. Maintenance recommendations include pressure washing the steel truss yearly, installing additional embankment protection at two locations, periodically cleaning debris from bearings, and repairing damaged railing. The load rating found the bridge to be above legal loads with no posting required. The related federal contract opportunity is a solicitation from the Federal Highway Administration for the Mitchell Street and Black Rock Road Reconstruction project in Polk and Mitchell counties, Oregon.
