This document is Attachment A to an Illinois Tollway contract specification, prepared by the State of Illinois for the Illinois Tollway Authority under the State Supplemental Provisions (Version 20.1).

The attachment provides technical specifications and engineering drawings for a 12" Aluminum Extrusion, Type B sign panel extrusion. The specifications include detailed dimensional drawings and construction details for the aluminum extrusion component, which appears to be used for highway signage on the Illinois Tollway system. The drawing indicates specific measurements, spacing requirements (including 12" spacing notation), and structural details for the extrusion profile. This is a specification document establishing the technical requirements and design parameters for the manufactured component rather than a pricing or procurement document.
