Maryland County Commissioners Section 99

      Where any ditch, drain or other improvement established under the provisions of this subtitle crosses a public highway at the intersection of such highway with a natural watercourse or depression through which water flows during periods of high water, the cost of bridges, or of repairing or enlarging existing bridges and culverts, or of constructing new ones, shall be borne by the county in which such bridges are located or by such other authority as is required by law to maintain such highways so intersected; and such bridges or culverts shall thereafter be maintained by such county or other authority. Where any ditch, drain, or other improvement established under the provisions of this subtitle crosses a public highway at a point where such highway does not intersect a natural watercourse or depression, the cost of constructing the new bridges shall be borne by the drainage association, provided that such new bridges or culverts shall thereafter be maintained by and at the expense of the county or other authority required by law to maintain the highways so intersected.
