Locomotive Act 1861

6 Use of Locomotives restricted over Suspension and other Bridges.

It shall not be lawful for the Owner or Driver of any Locomotive to drive it over any Suspension Bridge nor over any Bridge on which a conspicuous Notice has been placed, by the Authority of the Surveyor or Persons liable to the Repair of the Bridge, that the Bridge is insufficient to carry Weights beyond the ordinary Traffic of the District, without previously obtaining the Consent of the Surveyor of the Road or Bridgemaster under whose Charge such Bridge shall be for the Time being, or of the Persons liable to the Repair of such Bridge; and in case such Owner of the Locomotive and Surveyor of the Road or Bridge, or Bridgemaster, shall differ in opinion as to the Sufficiency of any Bridge to sustain the Transit of the Locomotive, then the Question shall be determined by an Officer to be appointed, on the Application of either Party, by One of Her Majesty's Principal Secretaries of State, whose Certificate of Sufficiency of such Bridge shall entitle the Owner of the Locomotive to take the same over such Bridge.
