placement and removal of spring load restrictions. As a result,
the end of spring load restrictions is no longer fixed at eight

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.
As soon as
a date is set, Mn/DOT will publish those dates on a 24-hour taped
message at 1-800-723-6543 for the USA and Canada (local calls
from Minneapolis/St Paul at 651-747-2253), The information is
