Exhibit_4_Roadway_Standard_.pdf

This document is a technical engineering drawing (Exhibit 4) from the Oklahoma Department of Transportation (ODOT) detailing specifications for a Concrete Longitudinal Barrier in NGHRP 360-J Shape. The detailed blueprints provide comprehensive technical schematics for roadway infrastructure, specifically focusing on design details for double-sided and single-sided inlet barriers with longitudinal barrier configurations. The drawings include multiple section views (A-A, B1-B1, B2-B2, C-C, D-D, E-E), bending diagrams, steel plate details, delineator placement plans, transition section details at bridge ends and piers, and an expansion joint detail.

The technical drawings include precise measurements, grade elevations, steel reinforcement specifications, and a quantitative basis of payment table. The drawings provide comprehensive engineering specifications for constructing concrete longitudinal barriers, including notes on construction materials, traffic staging, and installation requirements. The document includes design variations (Design 1-A), detailed dimensional specifications for barrier components, and a comprehensive set of general notes outlining construction standards, material requirements, and installation guidelines. The document is signed and dated, indicating official ODOT engineering approval for use in roadway infrastructure projects.
