It was in use again from October 22nd 1990, this time on a service from Lucan (Arthur Griffith Park) to Tallaght (The Square) via Clondalkin and Belgard Road. The service did not operate on Sundays. A complimentary service 74A also operated between Bawnogue and The Square during the same dates. It last operated on April 27th 1991.
Commencing operation on May 21st 2007, the number 74 was used for a service between Eden Quay and Stocking Avenue operating via Rathmines, Rathgar, Terenure and Templeogue. The route was introduced alongside sister route 74A as a peak time service in conjunction with the Transport 21 initiative. On September 30th 2007, the 74 was extended to a new terminus at Macken Street (set-down). The first pick-up stop was on Pearse Street. This extension was accompanied by a 7 day schedule with a much improved frequency. On January 18th 2009, the 74 was extended from the Macken / Pearse Street terminus to Britain Quay. Some early morning services operated from Ringsend (Bus Depot) via Pearse Street not serving Britain Quay.
From December 19th 2009, due to traffic congestion the 74 and 74A will operate from Britain Quay via Sir John Rogerson’s Quay, Lombard Street, Sandwith Street, Pearse Street and back on to normal route, returning via Townsend Street, Tara Street, Butt Bridge, Custom House Quay, Samuel Beckett Bridge and Sir John Rogerson’s Quay to Britain Quay on weekdays. Early morning departures will continue to operate from Ringsend Road (Bus Depot) via Pearse Street to normal route. On weekends buses will operate from Ringsend Road (Bus Depot) via Pearse Street to normal route, returning via Townsend Street, Tara Street, Butt Bridge, Custom House Quay, Samuel Beckett Bridge, Macken Street and Pearse Street to Ringsend Road (Bus Depot).
As part of Network Direct, the 74 was merged with the 15 and the 128 to create a new cross city service (utilising number 15). The 74 last operated on December 17th 2011.
November 26th 2023 saw the 74 rise again
