GENERAL NOTES 1. Flags attached to signs where shown are OPTIONAL.
2. All traffic control devices illustrated are REQUIRED, except those denoted with the triangle symbol are OPTIONAL. 3. Inactive work vehicles or other equipment should be parked near the right-of-way line and not parked on the paved shoulder. 4. A Shadow Vehicle with a ThtA should be used anytime It can be positioned 30 to 100 feet in advance of the area of crew exposure without adversely affecting the performance or quality of the work. If workers are no longer present but road or work conditions require the traffic control to remain in place, Twe .3 Barricades or other channelizing devices may be substituted for the Shadow Vehicle and ThtA. 5. Additional Shadow Vehicles with ThtAs may be positioned off the paved surface, next to those shown in order to protect wider work spaces. 6. Contractor shall provide and install traffic control devices in conformance with part VI of Texas Manual on Uniform Traffic Control Devices (ThtUTCD -Latest edition with revisions) during construction.
