PPS 6: Planning, Archaeology and The Built Heritage
Annex A: Existing Historic Structures
A5 Where work to transport structures which are listed or located in conservation areas is needed to meet new national or European requirements, the Department will carry this out with great care. For example many bridges are of considerable age and represent important features of the built heritage. Their survival to this day owes a great deal to the care of past generations, and, where remedial or strengthening works are found necessary, the Department will seek to retain the character of these structures for the benefit of future generations. Where new construction is the only realistic course of action, consideration will be given to the viability of retaining the historic structure for use by pedestrians and cyclists.
