Plan Set 2025 Helena Districts-SIGNED.pdf

This document is a detailed road maintenance plan set for the Helena-Lewis and Clark National Forest in Montana, covering multiple counties including Broadwater, Cascade, Glacier, Jefferson, Lewis and Clark, Powell, and Teton. The plan set consists of four sheets: a vicinity map, typical roadway sections, a 45-degree rolling dip design, and road maintenance signage specifications.

The first sheet provides a regional location map of the Helena Districts, showing the road maintenance project area. The second sheet details typical roadway cross-sections, including ditched and non-ditched templates for straightaway sections and turnout areas. The third sheet illustrates a 45-degree rolling dip design with specific engineering notes on excavation, embankment, and vertical curve requirements. The final sheet shows a standard "Road Machinery Ahead" sign specification, indicating 36" x 36" reflective black-on-orange signage to be placed 12" above the traveled way at both ends of current road maintenance operations.
