"This year Mn/DOT is using an improved system for determining
the end date of spring load restrictions," said Dave Van Deusen,
Mn/DOT Pavement Design Engineer. The end date is determined by air
temperatures, precipitation and frost depth of the preceding winter.
The freezing weather in southern Minnesota this year was mild compared
to most years and compared to the northern part of the state. This
has improved road strength earlier than some years.
Spring load restrictions help preserve roadways when the pavement
is weakened due to partial thaw conditions and trapped water. Mn/DOT
estimates the restrictions result in an annual savings of more than
$10 million. In Minnesota there are about 39,000 miles of paved
roads that should be restricted to lower loads during the spring.
