(2) 25 miles per hour: upon sections of park road under repair or construction.

(3) 45 miles per hour: upon all other park roads.

(b) The superintendent may designate a different speed limit upon any park road when a speed limit set forth in paragraph (a) of this section is determined to be unreasonable, unsafe or inconsistent with the purposes for which the park area was established. Speed limits shall be posted by using standard traffic control devices.
