ST. PAUL, Minn. – Spring truck weight restrictions on state highways begin March 14 for Minnesota's South, Southeast and Metro frost zones, according to the Minnesota Department of Transportation.
Winter load increases and overweight permits remain in place for the state's Central, North-Central and North frost zones.
MnDOT limits truck weights to prevent damage to roads weakened during the spring thaw. Ending dates for spring load restrictions will be established by monitoring roadway strength as weather conditions change.
The South Zone extends south from the southern limit of the Central Zone (US 12 – Hennepin county line) to the Iowa state line and east to the Metro Zone and then a line following and including Interstate 35. This zone includes Highway 19 along the southern border of Scott County.
The Southeast Zone extends south from the southern limit of the Metro Zone along, but not including, I-35 to the Iowa state line and east to the Wisconsin state line. This zone includes Highway 19 along the southern border of Dakota County.
The Metro Zone (Minneapolis – St. Paul metro area) includes Anoka, Carver, Chisago, Dakota, Hennepin, Ramsey, Scott and Washington counties. This zone does not include Highway 19 along the southern borders of Scott and Dakota counties.
