N.Y. Canal Law § 62
All highway or pedestrian, lift or movable bridges over the canal system other than highway bridges connecting parts of a state highway heretofore constructed as a part of the barge canal improvement shall be reconstructed, improved, maintained and repaired at the expense of the state, if in the opinion of the commissioner of transportation, the public convenience requires such bridges to be maintained where no alternate crossing has been provided. In the event the commissioner of transportation determines that any such bridge is no longer required for the convenience of the public, he shall have power to close, remove or relocate such bridge. The commissioner of transportation shall have the supervision and direction of such reconstruction, improvement, maintenance, repair, closing, removing or relocation. All bridges over the canal system other than lift, movable, pedestrian or state highway bridges heretofore constructed as part of the barge canal improvement shall be reconstructed, improved, maintained and repaired at the expense of the state under the supervision and direction of the commissioner of transportation, if, in his opinion, the public convenience requires that each such bridge shall be continued as a bridge for highway traffic. In the event the commissioner of transportation is requested by any municipality to reconstruct or improve any such bridge, he is hereby empowered to do so, provided, however, that prior to such reconstruction or improvement the municipality enters into a written agreement that such bridge thereafter shall become a part of the highway system or systems which it may connect and the maintenance, repair, improvement, replacement or closing of any such bridge shall be governed by the provisions of the highway law, except that any such bridges situate in a city shall be maintained, repaired, improved, replaced or closed in the same manner and subject to the provisions of any special law which may apply or to the same provisions of law as apply to other streets and bridges in such city or in the case of such bridges situate in a village, such bridges shall be maintained, repaired, improved, replaced or closed in the same manner and subject to the same provisions of law as apply to other streets and bridges in such village. Any bridge over the New York state canal system or abandoned part thereof which joins parts of a state highway shall be under the jurisdiction of the commissioner of transportation and deemed to be part of the state highway system and such bridges shall be constructed, reconstructed, improved, maintained, repaired, closed or relocated pursuant to the provisions of the highway law and the cost of such work shall be paid from moneys available for construction, reconstruction, improvement, maintenance or repair of state highways.
