Spring Load Restrictions

It is the Department's position to not implement Spring Load Restrictions any earlier than necessary. The Department monitors the daily high/low temperatures at numerous locations throughout the state. The high/low temperatures are used to calculate accumulated freeze and thaw indexes. Please be aware that this method is only one decision tool the Department uses to determine when to implement and remove load restrictions. The Department still relies heavily on the existing highway conditions and past experience of its field personnel when making the final decision of when to implement and remove load restrictions.

Under the authority of SDCL 32-22-24, a Highway Maintaining Authority may restrict loads on their highways anytime during the period from February 15 to April 30. The purpose of the load restrictions is to protect the highways from break-up during the spring thaw.

County road posted load limits are not determined or enforced by the State. Please use the information below to contact the county for questions/concerns on county road load limits. 

Under the authority of SDCL 32-22-24, a highway maintaining authority may limit weights on highways anytime during the period from February 15 to April 30. The purpose of these load limits is to protect the highways from break-up during spring thaw. The linked map above shows the proposed 2020 State Highway Spring Load Limits. These limits are subject to change as conditions warrant. Actual load limit posting takes precedence over those listed here and are in effect only when the load limit signing is in place.
