About this file

This document consists of Oregon Department of Transportation (ODOT) Standard Drawings for Midwest Guardrail Systems, specifically addressing guardrail installation specifications and components. The drawings provide technical guidance for the emergency guardrail removal and replacement project on US Highway 26 at milepost 107.9-110.1 in Jefferson County, Oregon, where fire-damaged guardrail and associated components require immediate replacement. The project scope includes removal and replacement of up to 642 rails, 1,313 steel posts, 1,313 poly blocks, and four end treatments on the southbound shoulder on the west side of the highway. The damaged rail to be replaced will be marked with white painted "X" marks. All materials must comply with current Oregon Standard Specifications, and all work must be designed in accordance with these standard drawings under the direction of a registered professional engineer. The vendor is responsible for providing all traffic control, as traffic control will not be provided by the agency.

The standard drawings specify detailed requirements for Midwest Guardrail System components, including W-beam and Thrie beam rail elements available in multiple effective lengths (6.25 feet, 12.5 feet, and 25 feet), steel posts (W6x8.5 or W6x9), wood blocks (6x8 or 8x8), and installation hardware including bolts, nuts, washers, and anti-rotation nails. The drawings cover specific installation procedures for various conditions, including placement on slopes with different slope ratios and shoulder widths, terminal configurations, and proper spacing and alignment requirements. All posts within a guardrail run must be of the same type (either wood or steel), and blocks must be routed or toe-nailed to prevent rotation based on post material. The effective dates for these standard drawings are June 1, 2026 through November 30, 2026, indicating current regulatory compliance requirements for the project.
