When determining the appropriate location to install traffic control devices, consider the location of trees, sidewalks, billboards, commercial signs, etc. that may obscure the visibility of the devices. Minor adjustments to locations shown on the plans may be made to accommodate existing site conditions prior to installation.

	Once in place, traffic control devices are to be clearly identified in AASHTOWARE Project (AWP) using the DWR Template for Construction Signs. When access to AWP is not immediately available, documentation may be recorded in a bound field book, signed by the inspector making the entry, and later entered into AWP. Identification of traffic control devices is necessary to avoid duplicate payment. Identification can be made by location (Sta, Log mile, GPS, etc.) or other descriptions that distinguish that device from all others. For example, it would be acceptable to identify a group of Road Work Ahead signs by stating, “Seven Road Work Ahead signs installed today on each of the seven county road approaches on Rte. J”. Portable sign packages can be identified as groups, for example, “Six sets of portable sign packages for flagger control were authorized today on Rte. 24, three sets were used for the cold milling operation and three sets were used for the asphalt operation”. Significant changes or additions to the traffic control plan should be documented. Adjusting the location of signs to improve visibility or effectiveness would not be considered a significant change. The final quantity of traffic control devices should reflect the maximum amount of authorized devices that were in place at any point in time, thus avoiding duplicate payment for devices that are relocated or used multiple times. All temporary traffic control devices should be authorized by [~~https~~:~~//epg.modot~~.~~org/forms/CM/AWP_CO_Documentation_Records~~.~~docx~~ documentation record~~, AWP_CO_Documentation_Records~~]. Documentation records are created to document temporary traffic control devices that are normally removed or covered up as construction progresses (with the exception of [[620.1 General (MUTCD Chapter 3A)#620.1.6 Permanent Pavement Markings\|permanent pavement marking]]). It is important to issue the documentation record promptly to let the contractor know what is going to be paid while the temporary devices are still in place so that if the contractor has a dispute the issue can be resolved before the device is removed or changed. Therefore, the documentation record is created automatically as a part of the contractor’s payment estimate when the estimate is generated and can be sent to the contractor at that time.

 The traffic control plan set up in the contract is to be studied very carefully.  Generally, traffic control plans are custom designed for each project.  This plan is to cover all construction phases needed to construct the project, but it may be necessary to adjust it to adequately protect the public or the workers.  If changes to the traffic control plans are being considered, the project designers and/or district traffic staff are to be consulted based on the magnitude of the proposed changes.

	The ROAD CLOSED sign may now be placed on the Type 3 barricade face. The sign does not need to be placed on a separate sign support post. Placement on the barricade face will require the use of a roll-up sign, lightweight plastic sign substrates or corrugated plastic sign panel to be considered crashworthy. Metal signs are not allowed. The use of ordinary hardware snaps (two male fasteners, with screw, on each of the top two rails and a female fastener near each of the sign corners) make for an efficient means of affixing a roll-up sign, with or without its ribs, to the face of a Type 3 barricade, while providing an effective and safe installation.

Make sure any permanent traffic control devices in conflict with the temporary traffic control devices (such as speed limit signs) are covered or removed. Frequent nighttime inspections are to be made to ensure that the devices have the proper reflectivity or lighting so they are visible and meaningful to the traveling public.

When not in use, the CMS needs to be turned away from traffic or removed from the roadway if it will not be required for more than 24 hours. A document log needs to be maintained in the inspector’s diary on when and what messages are displayed on CMS, to include when no messages were shown.

	It is very important to continually check temporary traffic control devices to see that they are adequate, kept in good repair, clean and covered, set aside or removed when no longer needed. Make sure any permanent traffic control devices in conflict with the temporary traffic control devices (such as speed limit signs) are covered or removed. Frequent nighttime inspections are to be made to ensure that the devices have the proper reflectivity or lighting so they are visible and meaningful to the traveling public. Refer to [[616.19 Quality Standards for Temporary Traffic Control Devices\|the ''Quality Standards for Temporary Traffic Control Devices'']] for further guidance.

	According to [https://www.modot.org/media/16892 Standard Plan 616.10], the mounting height for Type 2 portable signs may be 12 in. when the installation is for three days or less. This means that Type 2 portable signs may be used on work zones that the location varies from day to day and does not occupy the same location for more than three consecutive days, such as asphalt paving operations, guardrail installations, diamond grinding, etc. In such cases, the project may be ongoing for months, but the work zone locations moves up and down the roadway and do not occupy the same location from day to day.

	The pilot vehicle operator needs to be certified as a flagger and certification is to be verified. The pilot vehicle needs to be equipped with a communication device, the “Pilot Car Follow Me” sign and a warning light. The access control and signing for each side road located within the work area of the one-lane, two-way operation should be determined as discussed in [[616.3 Temporary Traffic Control Elements (MUTCD Chapter 6C)#616.3.10.1 Side Roads within the Work Area for One-Lane, Two-Way Operations\|EPG 616.3.10.1]].
