Foam-Jacking Scheduled On Highways In Fall River County

      The South Dakota Department of Transportation says several repair jobs are scheduled this week in Fall River County where several sections of highways have sunken.

       The $110,000 foam jacking project will see contractor Nortex Concrete Lift and Stabilization pump polyurethane foam into the voids under the paving.

      A chemical reaction converts the liquid components into a strong but lightweight rapidly-setting foam with a compressive strength of 100 pounds per square inch. Traffic can generally resume in less than an hour.

       Work is scheduled Tuesday and Friday on Hwy 79 southbound between Fairburn and Maverick Junction, and on Hwy 385 northbound from the state line to Oelrichs on Tuesday, Wednesday, and Friday.

       Projects between Maverick Junction and Hot Springs on Hwy 18 westbound are set for Thursday.

        More foam jacking work, including some in Custer County, is scheduled for next week. 

      Monday and Tuesday will see crews on Hwy 16 about 2 miles north of Crazy Horse and on Hwy 385 between Hot Springs and Wind Cave National Park and between Hwy 16 and Spirit Lake/

     Traffic will be reduced to single lane on all 2-lane routes while multi-lane routes will have a one lane closure. Flaggers will be used and motorists can expect slight delays
