The Federal Highway Administration (FHWA) awarded $160,000 through the Highway Planning and Construction program (CFDA 20.205) to the State of South Dakota on June 11, 2025, for infrastructure rehabilitation in Aurora County. The project encompasses replacement of a 72-inch diameter reinforced concrete pipe (RCP) measuring 60 feet in length and a 96-inch diameter corrugated metal pipe (CMP) measuring 116 feet in length at an intersection, along with associated roadway embankment reconstruction. The work is located approximately 6.0 miles north and 2.8 miles east of Plankinton on 247th Street between 388th and 389th Avenues in South Dakota.

In addition to pipe replacement and embankment stabilization, the project includes placement of 6 feet of base material and 4 feet of gravel surfacing, followed by reseeding of affected areas. These activities support the FHWA's objective to improve and preserve highway infrastructure through culvert restoration and roadway rehabilitation, addressing critical transportation network needs at the local level in accordance with the Infrastructure Investment and Jobs Act authorization framework.
