About this file
This interim bridge inspection report documents the findings of an inspection of the West Fork Sulphur Creek bridge. The inspection identified widespread failure of the existing lead-based paint coating on all exposed steel components of the superstructure, including bearings, cross bracing, girders, and other elements. The report recommends full removal of the lead-based paint using shot blasting and negative pressure containment, followed by repainting of all exposed areas.
The related federal contract opportunity is a solicitation from the Department of Transportation Federal Highway Administration seeking preservation work on the West Fork Sulphur Creek bridge to address the paint issues identified in the inspection report. The solicitation number is 69056720B000013 for contract CA NPS BP LAVO 2019(1). The opportunity type is a solicitation and response dates are not provided.
