About this file
This document is a technical specification exhibit prepared by the Oregon Department of Transportation for Klamath County's Highway 424 milepost route identifier project. The exhibit provides detailed engineering drawings and specifications for the design, fabrication, and installation of milepost markers along a 5.96-mile segment of Highway 424 in Klamath Falls. The project scope requires contractors to supply all labor, materials, equipment, mobilization, and machinery necessary to remove existing ground-anchored milepost markers, bundle them for return to ODOT, and install new milepost markers in accordance with the specifications outlined in the drawings and notes. The milepost signs are 10" x 27" aluminum panels with white retroreflective sheeting and green retroreflective legend borders, fabricated to conform to Oregon Standard Specifications for Construction sections 940 and 2910, as well as Federal Highway Administration standards.
The technical specifications establish detailed requirements for sign materials, construction, and installation procedures. Signs must be fabricated from sheet aluminum with a nominal thickness of 0.063 inches and feature ASTM Type III or Type IV retroreflective sheeting. Posts are constructed from sheet aluminum with a nominal weight of two pounds per lineal foot, with typical heights ranging from 4 to 12 feet depending on ground slope conditions and right-of-way limitations. Installation must occur at the edge of the traffic lane or shoulder, with specific positioning required at guard rail locations and curved road sections. The document specifies bracket assembly requirements for two-lane roads, mounting hole specifications using aluminum blind rivets, and compliance with subsection 840.41 of Oregon Standard Specifications. All installation locations are to be field-verified with the Engineer, and existing signs not included in the proposed design are to remain in place unless otherwise directed.
