Using the new Dublin city route navigation system

Updated  2003.10.25

Dublin now has three ring (orbital) route systems each with their own colo(u)r code:

1)  The M50 blue route is a motorway standard C ring road (périphérique). 

2)  The outer city ring colo(u)r coded purple.

3)  The inner ring road around the downtown area colo(u)r coded light blue.  Broadly speaking this incorporates zones 1, 2, 7 and 8 which appears on mailing addresses after the word "Dublin".

It is worth getting to understand the system if you plan to drive or cycle in the Dublin area.  (Bicycles are prohibited on the M50 route).

Each junction along each of these ring routes has a number, making it easy to know when you have reached a particular point.  For example, to get to the Phoenix Park follow the purple signs (outer city ring) to junction 65.    This eliminates the need to constantly refer to a map when driving across town - simply look at the map before you set out to determine your destination junction number on either the purple or light blue orbital routes or the M50 ring - and follow the signage system to get to that point.
