About this file
This document is a traffic control design specification sheet from the Kansas Department of Transportation (KDOT) for road and sidewalk closures. The technical drawing provides comprehensive guidelines for implementing traffic control measures during road construction or maintenance projects, specifically detailing the placement of barricades, signage, warning lights, and pedestrian detour strategies. The specification includes four detailed figures illustrating typical signing scenarios for road closures on main lines and side roads, as well as sidewalk closures, with precise measurements and positioning instructions for barricades, channelizing devices, and warning signs.
The technical specification outlines specific requirements for barricade types, including Type 3 barricades with lights, detectable barricades, and pedestrian barricades. Key details include rules for sign placement, such as not covering more than 50% of the top two rails or 33% of the total barricade area, mounting low-intensity warning lights, and using specific road closure signs like R11-3a and R11-4 depending on the distance to the roadway closure point. The document provides general notes on barricade usage, warning light restrictions, and guidelines for maintaining traffic flow while ensuring public safety during road work zones.
