SDCL § 46A-10A-76: Highway bridges and culverts--Construction--Maintenance--Modification--Costs.

Contracts for building public highway bridges and culverts necessary after construction of a drainage project may be let separately after the project is completed. The expense of constructing bridges or culverts initially shall be charged as part of the drainage costs, but thereafter such bridges and culverts shall be maintained as part of the highway. The expense of removing, repairing, enlarging, or replacing existing bridges or culverts across the line of a proposed drainage project shall be borne in equal shares by the drainage project and the county highway fund.
