ST. PAUL,
Minn.- The Minnesota Department of Transportation announced today
that spring load restrictions will take effect in the south, southeast
and eight-county Twin Cities metropolitan area frost zones at
12:01 a.m. on Wednesday, March 23. Winter load increases will
end at 12:01 a.m. on March 24 in the central frost zone and restrictions
will go into effect in the central zone on March 25. Spring load
restrictions in the north central and north frost zones will be
announced as temperatures dictate.
Spring load restrictions restrict the weight on any single axle
on all non-exempt trucks and commercial vehicles to a maximum
of five tons on non-concrete state highways, county highways,
town roads and city streets unless otherwise posted.
Locations of weight restricted routes, frost zone designations,
state highways open to maximum ten-ton axle weights and current
updates regarding spring load restrictions can be found on the
Web at http://www.mrr.dot.state.mn.us/research/seasonal_load_limits/sllindex.asp
or call 1-800-723-6543 (toll free) or 651-406-4701.
Mn/DOT uses
actual and forecasted daily air temperatures to determine the
placement and removal of spring load restrictions. As a result,
the end of spring load restrictions is no longer fixed at eight
weeks. Start and end dates of load increases and restrictions
are posted on the Web at least three calendar days in advance.
Road preservation
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.
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
also published on the Mn/DOT Seasonal Load Limits website: www.mrr.dot.state.mn.us.
