About this file
This document contains drawings and design details for the Dry Fork Road Culvert Replacement project in Phillips County, Montana. The project is being managed by the Bureau of Land Management's Malta Field Office.
The key details include:
- Replacement of two existing 48-inch diameter, 80-foot long corrugated steel pipe culverts under Dry Fork Road
- Construction of a temporary detour road with a maximum 10% grade and 50-foot minimum radius curves to allow traffic flow during construction
- Excavation and embankment details, including approved borrow areas along the existing road cuts
- New culvert specifications, including 96-inch diameter polymer-coated corrugated steel pipe with concrete headwalls, splash pads, and cutoff walls
- Construction details for the culvert bedding, connections, and placement
- A road profile showing the existing and proposed road elevations and grades
This document provides the technical specifications and design plans for the culvert replacement project, but does not contain any information about the federal contract opportunity or procurement process.
