text: Belfast has ALOT of highways that are tagged as Trunk Road. Compare this to the centre of English cities such as Manchester where Primary Roads are the main type in use but is seldom used in Belfast (see Castlereagh Road). 
  
  Do we really think Crumlin Road, May Street, N'ards Road are equivalent to the Westlink and Sydenham Bypass in terms of spec and use?
  
  The same can be said for other NI towns
