A construction project to repair two box culverts in Lyman County is scheduled to begin today (Sept. 8, 2022), which means a stretch of SD Highway 273 is closed.
The South Dakota Department of Transportation says the project begins on Highway 273 at the box culvert site located approximately 3.5 miles north of Kennebec (mile marker 66) and will end at the box culvert site located approximately 6.5 miles north of Kennebec (mile marker 69). To complete this work, SD Highway 273 will be temporarily closed at each of the two box culvert sites.
The box culvert at mile marker 66 is tentatively scheduled to be closed from today through Sept. 19, 2022. The box culvert located at mile marker 69 is tentatively scheduled to be closed Sept. 20-29, 2022. Traffic is advised to use alternate routes when traveling through this area during these closures.
The project includes the repair of two reinforced box culverts that had been temporarily repaired to ensure the roadway remained safe for travel. The permanent repair will require excavation of all material around each box culvert so that the joints inside and outside the box culvert can be exposed and repaired.
