A huge change.
The National Transport Authority has formally confirmed that two Dublin Bus routes are set to become 24-hour services on 1 December, 2019.
The 15, which travels from Clongriffin to Knocklyon, and the 41, which travels from Abbey Street to Swords, will become the first two routes to operate on a round-the-clock basis. The 41 also stops at Dublin Airport.
From the start of next month, both services will run buses every half an hour between midnight and 5am.
The NTA has also confirmed that "daytime frequency on the 15 and the 41 will improve," though no specifics are available on this yet.
Not only that, but the fare structure will remain unchanged, which means there will be no additional charge to the customer for travelling late at night. Buses after midnight will continue to accept Leap Cards, Free Travel Cards and cash.
NTA CEO Anne Graham said: "The manner in which Dublin functions as a city has shifted gradually but dramatically in recent years. It is no longer the case that city shuts down at 11 or 12 at night.
"The patterns of work and socialising have changed. For instance, the success in attracting to the city, major employers who are headquartered many time-zones away, serving markets around the world, means that commercial and economic activity in Dublin continues around the clock.
"The airport has become busier and busier, in recent years, and is itself a major employer. There is a clear demand for more transport options to the airport, not just for their passengers, but for the thousands of people whose jobs require them to be at work early in the morning or late into the night."
