Pre-Trip Route Survey Information and Requirements
- Is required when an oversized load exceeds 16'0" in height and/or 20'0" in width. In some cases, excessive length may require a route survey;
- Is to be performed before the load moves and before a MnDOT permit will be issued;
- Requires a physical survey of the complete proposed route to ensure clearance; and,
- Is the responsibility of the operator/motor carrier transporting the load (Permittee), regardless of who conducts the actual pre-trip route survey.
A route survey can remain valid for up to sixty (60) days, as long as subsequent movements are of the same dimensions as initial survey; are transported by the same carrier; and at least one movement happens within a fourteen (14) day period.
Permit issuance may be delayed if routes are entered incorrectly or incompletely on the MnDOT permit application and/or on the route survey.
- For loads exceeding 16'0" high - a nonconductive, nondestructive, flexible, and readily breakable height pole must be used and set as a minimum of six inches (6") higher than the highest part of the load;
- For loads exceeding 20'0" wide, a minimum of one foot (1'0") lateral clearance is required through construction work zones;
- Visit www.511mn.org for current road conditions and construction project information.
- A minimum of six inches (6") is required underneath all vehicle components;
- Identify all railroad at-grade crossings along the route and verify that the loading can navigate those RR crossings safely and quickly;
- Notify utility companies for approval to raise or move their overhead wires;
- Obtain approval to operate on local roads. MnDOT permits are not valid for local roads; and,
- No obstructions can be moved or removed without written permission from the owner.
- The Pre-Trip Route Survey must identify which traffic lane is to be used to maneuver under a low clearance;
- Maneuvers, such as backing up or using opposing traffic lanes, must be clearly listed;
- Complete route (including county and city roads) must be listed to show route continuity;
- County names must precede county road numbers (example: Sherburne CR11);
- Direction of travel for each road segment must be identified (example: N, S, E, W);
- The permit application route must match the survey route; and,
- Surveys will not be processed if information is missing or illegible.
MnDOT reserves the right to not accept a route survey if information is not entered correctly or if the information provided does not meet our criteria.
