Subject to paragraph (2) the undertaker may in connection with the carrying out of the authorised development stop up the sections of the public rights of way described in paragraphs 1, 3 and 5 of Schedule 7 (public rights of way) and with effect from the date that each of those sections of those public rights of way are physically stopped up by the undertaker in connection with the carrying out of the authorised development, the public rights of way over each of those sections are extinguished.

If the undertaker stops up the public rights of way described in paragraphs 1, 3 and 5 of Schedule 7, it must construct the alternative replacement sections of public rights of way described in paragraphs 2, 4 and 6 of Schedule 7 and with effect from the date of opening to the public of each alternative replacement section of public right of way, public rights of way of a restricted byway over each section so constructed are created.
