This Order amends the Planning Act 2008 (c.29) (“the Act”). It substitutes a new section for section 22 (Highways), and amends section 25 (Railways). Sections 22 and 25 of the Act set out where highway-related development and where the construction or alteration of a railway fall within the respective scope of section 14(1)(h) and (k) of the Act so as to represent “nationally significant infrastructure projects” for the purposes of the Act. Nationally significant infrastructure projects require development consent under the Act before they can proceed.
