14. (1) Where the railway administration has constructed the railway across a public road on the level, the Government may at any time, if it appears to it necessary for the public safety, require the railway administration, within such time as it thinks fit, to carry the road either under or over the railway by means of a bridge or arch, with convenient ascents and descents and other convenient approaches, instead of crossing the road on the level, or to execute such other works as, in the circumstances of the case, may appear to the Government to be best adapted for removing or diminishing the danger arising from the level-crossing. (2) The Government may require as a condition of making a requisition under sub-section (1), that the local authority, if any, which maintains the road, shall undertake to pay the whole of the cost to the railway administration of complying with the requisition or such portion of the cost as the Government thinks just.
