This document is a detailed engineering design drawing for a bridge project prepared by the State of Montana Highway Commission, specifically for a bridge over the Northern Pacific Railway at Sta. 159+56.80, Federal Aid Project No. 116-9-584(36). The drawing provides comprehensive technical specifications for bridge construction, including profile grades, roadway alignments, and cross-sectional views of both westbound and eastbound roadways. The plan includes multiple detailed sections showing elevation changes, geometric measurements, and structural design elements for the bridge infrastructure.

The technical drawing includes precise engineering measurements, noting various station points, horizontal and vertical alignments, and specific construction details. The project appears to be located near an interstate highway (I-90), with detailed annotations for bridge deck, rail, and roadway configurations. The document contains a references section, scale notations, and is part of the State of Montana's transportation infrastructure improvement efforts, likely funded through federal aid transportation project funding.
