This Section describes requirements associated with maintenance of traffic (MOT), including providing for
the safe and efficient movement of people, goods, and services through and around the Project while
minimizing negative impacts to residents, commuters, and businesses. It also describes allowable road/lane
closures, requirements for a Transportation Management Plan, and the duties of the MOT Traffic Control
Supervisor.

Administrative Requirements
18.2.1
Standards
In the event of a conflict between the standards set forth in Book 3 relating to maintenance of traffic, the
order of precedence shall be as set forth below, unless otherwise specified:
 MnDOT Special Provisions
 MnDOT Standard Specifications for Construction
 Minnesota Manual on Uniform Traffic Control Devices (MnMUTCD)
 Minnesota Standard Signs Manual
 MnDOT Traffic Engineering Manual

MOT shall accommodate a WB-62 design vehicle unless otherwise specified or Approved by MnDOT.
18.3.3.2 Temporary Guardrail, Barrier, Attenuators, and Glare Screen
Use temporary guardrail or barrier and attenuators to protect the traveling public from the following:
 Fixed objects within the clear zone
 Drop-offs that are not in accordance with the traffic control treatment of longitudinal joint and edge
drop-off guidelines in the MnDOT Temporary Traffic Control Zone Layouts Field Manual
 Slopes steeper than 1:3 (V:H)
Follow the requirements of the Traffic Engineering Manual, Chapter 8, for portable precast concrete barrier
(PPCB) delineation. Use PPCB linear delineation panels for the first 500 feet of any concrete barrier used in
alignment shifts, lane transitions, or bypasses. Use two 34-inch linear delineation panels of the appropriate
color spaced 26 inches apart per barrier section.
To reduce the headlight glare of approaching vehicles through horizontal curves, place temporary glare
screen meeting MnDOT Standard Plate 8326 on top of all PPCB that separates opposing traffic. Ensure
guardrail installation conforms to MnDOT Standard Plate 8307.
18.3.3.3 Pedestrian Access
Maintain pedestrian access on all existing sidewalks, paths, and intersections unless Approved by MnDOT or
otherwise noted.
The Contractor must demonstrate pedestrian access cannot be maintained before a detour will be considered
by MnDOT. If MnDOT agrees that access cannot be maintained, obtain Approval from MnDOT and all
other appropriate governing agencies to close or modify the pedestrian access. If an access closure is granted,
provide a signed detour route for the pedestrian access.
The alignment of the existing sidewalk or path can be temporarily relocated within MnDOT right of way to
avoid pedestrian conflicts with the work area. Provide a safety buffer between the temporary sidewalk or
path location and the work area. The temporary shift in the alignment of the sidewalk or path would not be
considered a detour and would not require signing or Approval by MnDOT.
