WASHBURN COUNTY -- Maintenance crews from the Washburn County Highway Department plan to chip seal WIS 77 beginning July 31.

During chip sealing operations, the road will be open to through traffic. The work will be completed using lane closures with flagging operations between 7 a.m. and 6 p.m. Motorists can expect travel delays and may want to consider alternate routes. Schedules are dependent on weather conditions and are subject to change. Chip sealing operations will span from the Sawyer/Washburn County Line to Verns Road, a 2.57-mile section of WIS 77. Chip sealing both directions is expected to take about two days.

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 highway temporarily during the initial cure of the asphalt. Once the chip seal has cured, crews will sweep the highway to clear away loose stones.

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