City of sioux falls; replace 2 - 24' DIA RCP sections and CMP downspouts, place additional riprap, rebuild embankment/inslope, seeding and mulching, T

The Federal Highway Administration awarded the State of South Dakota Office of the Governor $254,185 on December 11, 2025, under the Emergency Relief (ER) Program (CFDA 20.271) to fund highway infrastructure repair in Sioux Falls.

The project replaces two 24-inch-diameter reinforced concrete pipe (RCP) sections and corrugated metal pipe (CMP) downspouts, places additional riprap, rebuilds embankment and in-slope conditions, performs seeding and mulching, and provides traffic control at Interstate 29 South Exit 81 southbound on-ramp (MRM 81, PCN I7NR). Performance occurs in South Dakota with an ultimate completion date of October 4, 2028. The State of South Dakota, which functions as the administrative pass-through recipient for Federal Highway Administration transportation grants statewide, receives the award and directs the work. The Emergency Relief Program provides permanent annual contract authority of $100 million from the Highway Account of the Highway Trust Fund to repair Federal-aid highways and roads on Federal lands that sustained serious damage from natural disasters or catastrophic failures, and obligates funds directly to State Departments of Transportation to initiate repairs.
