Any person who undertakes to perform any work upon, in, under, above or about any public street, highway, roadway, alley or sidewalk, hereinafter collectively called public right-of-way, which requires that the street be partially or completely closed for construction maintenance operation which work shall require excavation within or occupancy of the whole or a portion of the width of any such public right-of-way by equipment, materials, debris or workmen shall use barricades, signals, flags, flares, and all other traffic-control and warning devices and procedures about the work area during the duration of the work within the public right-of-way of the type and in the manner required by the “Texas Manual on Uniform Traffic-Control Devices for Streets and Highways, part VI, Traffic-Controls for Street and Highway Construction and Maintenance Operations,” as it is currently written or is subsequently amended. Part VI of the manual is incorporated by reference for all purposes. Such persons shall also be required to obtain a permit from the Director of Transportation if the specifications stated in section 3, B-1-3, are applicable, with the exception of the state department of highways and public transportation conducting work on any state-designated system. In such cases, no permit is required. This permit must be required before construction is begun. Purpose of the permit is to ensure that ample consideration has been given to the effect of said construction work on the flow of traffic.

All such signs, devices and barricades should be in good condition, clean and legible and shall be of the type required by the “Texas Manual on Uniform Traffic-Control Devices;” provided, that the Director of Transportation may authorize the use of different or special devices and equipment if, in his opinion, such equipment will be at least as effective for its intended purpose as that set forth for such purpose in the “Texas Manual on Uniform Traffic-Control Devices.” When additional regulatory signs are deemed necessary by the Director of Transportation, such signing will be installed as directed by the Transportation Department along with such regulatory signs as are required to be provided by the City as required by the manual.
