Paragraph 5 I1

If in consequence of or in connection with the exercise of the powers of this Order any part of a way over land forming part of a dock area or any public right of way giving access to a dock area (“the closed section”) is temporarily closed to persons on foot or on cycles and there is no way which provides a reasonable alternative, DLRL shall to the reasonable satisfaction of the Board, provide in substitution as sufficient and convenient way as is reasonably practicable between the points of commencement and termination of the closed section for such time as the closure continues.
