The Codington County Board of Commissioners on June 4 approved sending bids for a resurfacing and reclamation project on County Road 10‑4 (169th Street) and County Road 7‑5 (460th Avenue) and authorized the South Dakota Department of Transportation to let project BRF‑B6127 on County Road 11‑1, a bridge replacement north of State Highway 20.
Randy (county staff) explained the resurfacing plan for the 5‑mile corridor: mill and overlay on the east‑west segments and a full reclamation on the north‑south three‑mile segment after geotechnical borings found asphalt depths of roughly 1½ to 1¾ inches—insufficient for heavy tandem‑truck hauling. He said the north‑south mileage will be reclaimed and base‑stabilized with a chemical stabilizer before paving, work that will be performed by a contractor separate from the paving contractor. Commissioners approved posting the bids (posting dates June 11 and 18; bids to be opened June 23).
Randy also presented the BRF‑B6127 letting request to replace a 1940 bridge on County Road 11‑1 with a box culvert. He said easements and utilities are in place and identified the project as an 80/20 cost share between the state and county; the county’s 20% share was stated as $288,540.80. Commissioners approved the authorization to post the project to SD DOT’s letting process.
During discussion, staff cited past work in the Waverly Southshore area as a comparable chemical stabilization approach and said the paving completion deadline will conform with DOT seasonal limits (October 15). Whan Blazius (Banner) accompanied staff and was available for technical questions. Both road items passed on voice votes recorded in the meeting.
The board did not amend the projects at the meeting; staff indicated mid‑July contractor availability for reclamation work and an August 1 early start date for paving, with seasonal completion by Oct. 15.
