1.03 Operations and Maintenance
(Updated 12/3/2020)
It is the responsibility of the operations engineer or a designated contact person to ensure that all state and contract maintenance activity is conducted in accordance with the WZSM Policy and Manual.
This includes the development of a TMP to appropriately mitigate and communicate any mobility and congestion issues within or adjacent to the work zone.
The maintenance and permitted activity work zones TMP should include the appropriate maintaining traffic details, work zone devices, and work requirements to address work zone safety and mobility impacts. Attachments to the TMP should also include analyses performed to determine time restrictions. Specific attention should be focused on the initial implementation of temporary traffic control and all temporary traffic control changes during staged construction.
Region/TSC Traffic and Safety staff may recommend times and days of the week to perform maintenance activities to reduce potential work zone impacts. Short duration (<3 days) maintenance activities that are scheduled to occur may be modified to accommodate local needs and reduce any potential work zone impacts to safety and mobility.
- A TMP is only required for maintenance work if that work is considered long-term stationary work (>3 days), as defined by the MMUTCD.
- Mobile activities should be reviewed with the Region / TSC Operations Engineer to determine the necessary level of documentation.
- Coordination with the Region/TSC Operations Engineer and the Traffic and Safety Engineer is required and mitigation measures need to be developed as part of the TMP.
1.03.01
(Updated 5/28/2021)
The MDOT Mobility Map includes mobility time restrictions for MDOT facilities. Routes with mobility time restrictions may require a TMP if long-term stationary (>3 days) work activities occur during restricted hours and the project impacts are significant, according to Section 2.01 Project Significance.
1.03.02 Non-Restricted Routes
Routes that do not have time restrictions for work activities require advanced notice to the Operations Engineer or the designated contact person. The required Temporary Traffic Control Plan (TTCP) should be documented and discussed with the Region/TSC.
1.03.03 Emergency Maintenance
(Updated 12/3/2020)
Emergency maintenance work is often of immediate nature and planning time is limited. To reduce impacts, maintenance staff should ensure the appropriate maintaining traffic details, temporary traffic control devices, work zone requirements, and public communications are implemented quickly. It is recommended that maintenance staff contact the TSC for assistance with the implementation of these items/actions.
The safety and mobility of the traveling public is still a primary factor in determining the TTCP for emergency work, but due to the limited timing and nature of the emergency work a formal TMP is not required. It is recommended that a meeting is held to discuss the impacts to traffic on emergency operations that are planned to have a duration of longer than 3 days.
