|Route outline (key)|
The T11 was a trunk route along the Atlantic Corridor in the west of Ireland, running from Cork to Sligo.
Today, the route has been split into separate National Primary roads (much of which has been bypassed as motorway), but the only significant change is between Tuam and Knock Airport, which originally ran further east along what's now the N83.
