This is a technical drawing/specification document for a Road Closure Gate system, specifically a U.S. Customary Special design prepared by the U.S. Department of Transportation, Federal Highway Administration, Central Federal Lands Highway Division.

The document presents detailed engineering specifications and construction drawings for a pipe gate mechanism designed for road closure applications. The system includes a pipe gate with mounting hardware, object markers (OM-3R and OM-JL specifications with 2' x 2' metal posts), and associated structural components. Key elements shown in the design include: a 3-inch diameter pipe main structure, sign mounting brackets, hinge systems, lock and center support details with threaded rod assemblies, pipe caps, removable bolts with finger-tightened square nuts, and reflective tape markings on gates. The document specifies multiple object marker locations along the gate alignment and includes detailed elevation and plan views of the lock mechanism, center support structure, and pipe gate configuration. Sheet 1 of 2 indicates this is part of a larger technical specification set (Sheet No. 619-B), with measurements provided in both feet and inches throughout all sectional details and elevation drawings.
