This prominent Dublin feature is first mentioned in Lotus
Eaters, when the elegant woman whom Bloom has been
ogling, waiting for her to climb up on a jaunting car and
reveal glimpses of her underwear, rides off "towards
the Loop Line bridge." The "bridge" here is quite
a few blocks from the water, passing over Great Brunswick
Street on its way to the nearby Westland Row (now Pearse)
railway station, where it terminates.
One chapter later, in Hades, the carriage in
which Bloom is riding along Great Brunswick (now Pearse)
Street passes "under the railway bridge"
near Westland Row station. In the space between the two
chapters Bloom has traveled southeast to Paddy Dignam's house in
Sandymount, and is now revisiting the area he walked
through before.
The bridge proper (that is, the part that crosses the
river) figures in Wandering Rocks, when the
throwaway which Bloom has thrown away on the O'Connell
Street bridge drifts past its pilings: "A skiff, a crumpled
throwaway, Elijah is coming, rode lightly down the Liffey, under
Loopline bridge, shooting the rapids where water
chafed around the bridgepiers, sailing eastward past hulls
and anchorchains, between the Customhouse old dock and
George's quay." In 1904 oceangoing ships moored both
upstream and downstream of the Loop Line bridge, navigating
past the immediately adjacent Butt Bridge by virtue of
its swiveling central section.
The action of Eumaeus takes place under the
northern part of the bridge, behind the Custom House.
Stephen and Bloom, we hear, "made a beeline across
the back of the Customhouse and passed under the Loop Line
bridge where a brazier of coke burning in front
of a sentrybox or something like one attracted their rather
lagging footsteps." This is the post of Gumley, guarding the
Corporation's stones.
From the nearby cabman's shelter, Bloom sees the old sailor
Murphy "gaping up at the piers and girders of the
Loop line rather out of his depth as of course it was all
radically altered since his last visit and greatly
improved." Bloom, then, is much in favor of this
recent feat of mechanical engineering in service of railway
connectivity, accomplished during Murphy's long absence. He
does not seem to be bothered by any aesthetic violence it
may have done to the Georgian cityscape.
At its northern end, the bridge runs into the Amiens Street
(now Connolly) station, the departure point for northbound
trains. This station too is mentioned in Eumaeus
and Ithaca.
