| | Proposed Re-Numbering of Northern Ireland Motorway and Junction Numbers - Northern Ireland Roads Site |
 | | Given the fact that the M3 was built to urban motorway standard with reduced hard shoulders and tighter curves, and given that some motorways in Britain have no hard shoulders at all, there is no real argument against doing this with the Westlink. |
 | | The motorways either in existance or being planned in the Republic of Ireland are the M1, M3, M4, M6, M7, M8, M9, M11 and M50. |
 | | The M3 motorway could be extended onto the Sydenham Bypass when it is upgraded in a few years' time with junction 3 for the new Harbour Estate interchange, 4 for the City Airport and 5 for Tillysburn. |
