Loop Line bridge
The "Loop Line bridge" is a heavy railroad bridge that
crosses the Liffey on the east side of central Dublin,
continuing over city streets on the north side to the Amiens
Street station and on the south side to the Westland Row
station. It was built in 1891 to connect train lines on the
two sides of the city, "looping" between the two stations in a
large arc. Its elevated structure, occasioned by the need for
ships and city traffic to pass beneath it, spoiled views of
the large, handsome neoclassical building just to the
northeast: the Custom House.
