About this file
This is a Standard Plan document issued by the Mississippi Department of Transportation (MDOT) detailing traffic control and construction barricade specifications for the Town of Tunica's 2026 paving project. The document provides comprehensive technical guidance on the design, construction, and placement of various work zone devices including Type I, II, and III barricades, Type 3 object markers, chevron signs, and plastic drums. The specifications establish requirements for reflective striping patterns, dimensions, mounting heights, spacing intervals, and placement distances from roadways. Key devices detailed include wing barricades for advance warning at construction projects and bridge operations, standard barricades with minimum reflective area requirements (270 square inches for high-speed roadways), black chevron signs mounted on crashworthy supports, and plastic drums with orange and white retroreflective striping. The document references compliance with the Manual on Uniform Traffic Control Devices (MUTCD) and FHWA crashworthiness standards for Category II work zone devices.
The specifications establish that barricades must meet FHWA crashworthiness requirements and reference acceptance letters for tested devices available on the FHWA website. All marking standards require orange and white retroreflective materials with specific stripe widths of six inches (or four inches when rail lengths are less than thirty-six inches) sloping downward at forty-five-degree angles in the direction of traffic flow. Plastic drums should be positioned no closer than three feet from the edge of the traveled lane and must never be placed without accompanying warning signs. These technical standards ensure uniform traffic control implementation across the paving project and establish safety protocols for construction work zones throughout the Town of Tunica.
