SBR-T5__10-28-1968_Rail.pdf

This is a standard steel bridge rail technical drawing (Drawing No. SBR-T5) prepared by the State of Montana State Highway Commission for Type No. 5 standard steel bridge rail design. The detailed schematic provides comprehensive engineering specifications for bridge rail components, including end post and terminal sections, sleeve expansion joints, rail splices, anchor bolt assemblies, and anchor plate details. The drawing includes multiple scaled views and cross-sections with precise measurements and construction notes, indicating specific technical requirements for steel bridge rail installation and construction.

The technical drawing includes detailed notes specifying material requirements, such as using high-tensile strength bolts, structural tubing, and galvanized components. The design appears standardized for state highway bridge infrastructure, with precise engineering specifications to ensure consistent rail installation across Montana's highway system. The drawing is dated 10-28-1968, suggesting it is a historical engineering standard that may have been referenced for the I-90 Bridge Rail Repair project, providing technical guidance for rail repair or replacement specifications.
