I actually thought that this was Lower Clanbrassil Street as it was closest to the canal but as the river Liffey is the reference body of water it is of course the upper section.

Clanbrassil Street is a street in Dublin south of the city centre. It runs from Robert Emmet Bridge on the Grand Canal to New Street. It is served by several bus routes.[1] It is divided into Clanbrassil Street Upper (south end) and Clanbrassil Street Lower (north end).

It is named after The 2nd Earl of Clanbrassil, an Ulster-Scots nobleman. Clanbrassil was the name of a Gaelic territory in what is now northern County Armagh.

In 1953 all residents of Clanbrassil St. received a notice from Dublin Corporation that residences on the west side of the street would have to have 16 feet (4.9 m) removed from the frontage of the properties to make way for a new road. This proposal was constantly changed or deferred, so that in the 1960s and 1970s the street fell into ruin.

One by one businesses, public houses and retail outlets closed up or were demolished, and that side of the road became a wasteland. By 1980 the road engineers had increased the amount of space needed to 60 feet (18.3 m), in order to run a 6-lane dual carriageway through the street, past St. Patrick's Cathedral on to Christ Church Cathedral.

After protests and demonstrations by locals and sympathisers against the road, and intervention by the Taoiseach, Charles Haughey, work on the road eventually began in 1989. A 4-lane dual carriageway was constructed, flanked by new houses and apartments. The cost of the road was estimated to be £2 million.

Among the features destroyed by the road construction was the crossing known locally as the "Four Corners of Hell" (the junction of Patrick St., Dean St., New St. and Kevin St.), because there was a public house on each corner; and the well-known hostelry The Bunch of Grapes (formerly Fitzpatrick's, constructed in 1739).
