Bridges or conduits heretofore or hereafter constructed in a permanent manner, whether by encroachment permit or otherwise, which cross county highways and which have been constructed or brought up to county standards, and have been accepted, either formally or informally by appropriate action, shall, after such acceptance, and regardless of who constructed them, be the sole responsibility of the county, so far as maintenance, repair, improvement for the benefit of the county, reconstruction or replacement of such bridges and conduits are concerned. If any such county highways become state highways, the State shall succeed to the foregoing obligations of the county.
The amendment of this section made at the 1963 Regular Session of the Legislature does not constitute a change in, but is declaratory of, the pre-existing law.
