Chip sealing starts July 10 near Winona, continues through five other counties

ROCHESTER, Minn. – Motorists will encounter minor traffic delays beginning July 10 as crews begin chip sealing work on various highways in southeast Minnesota to help preserve the roadways, according to the Minnesota Department of Transportation.

Work will begin July 10 and should be complete by August 31. Crews will start in Winona County and head west through Olmsted, Wabasha, Goodhue, Rice and Dodge counties.

Motorists will be stopped by flaggers who will ensure groups of vehicles safely move one direction through the construction zone while the other direction of traffic is stopped. Groups will take turns using the single open lane while being directed by flaggers. Delays should be minimal through the work zone.

Highways scheduled for chip sealing work include:

  • Highway 43 in Winona County between Highway 61 and I-90
  • Highway 248 in Winona County between Altura and Highway 61
  • Highway 42 in Olmsted County between Eyota and Plainview
  • Highway 247 in Olmsted County between Plainview and Highway 63
  • Highway 63 in Wabasha County between Lake City and Oak Center
  • Highway 58 in Goodhue County between Zumbrota and Red Wing
  • Highway 61 in Goodhue County between Highway 316 and Highway 19
  • Highway 19 in Rice and Goodhue counties between Northfield and Highway 61
  • Highway 57 in Goodhue County between Highway 52 and Wanamingo
  • Highway 56 in Rice and Dodge counties between Kenyon and West Concord

Chip sealing work involves applying a thin film of heated asphalt on the road surface, followed by the placement of small aggregates or "chips". The chips are then compacted to allow for maximum adherence to the asphalt, and excess stone is swept away. Chip sealing protects the pavement from the effects of sun and water, increases skid resistance, fills small cracks and other surface defects.

MnDOT urges motorists to always be attentive, drive with caution, slow down in work zones and never enter a road blocked with barriers or cones.
