Chip sealing planned on segment of WIS 85 in Dunn County

​​​​Release date: July 11, 2023

Maintenance crews from the Dunn County Highway Department plan to chip seal a 7.1-mile section of WIS 85 from the Pepin County line to County O at Rock Falls beginning either Thursday, July 13, or Monday, July 17.

A chip seal consists of a layer of crushed stone placed on top of an application of liquid asphalt to reduce further deterioration of the pavement.

Loose stones will be on the hi​ghway temporarily during the initial cure of the asphalt. Once the chip seal has cured, crews will sweep the highway to clear away loose stones.

During chip sealing operations, WIS 85 will be open to through traffic, but motorists will encounter single-lane closures controlled by a pilot car and flagging between 6 a.m. and 4 p.m. It's expected to take two days to complete all work.

Drivers are urged to take extra caution, drive slowly and allow additional space between vehicles to prevent damage from any loose stone chips.

Schedules are dependent on weather conditions and subject to change.
