THE ANGLESEA BRIDGE, CORK.

The river Lee flows through the city of Cork in two branches, which
diverge just above the city, and are reunited at the Custom House, the
central portion of the city being situated upon an island between the
two arms of the river, both of which are navigable for a short distance
above the Custom House, and are lined with quays on each side for the
accommodation of the shipping of the port.

The Anglesea bridge crosses the south arm of the river about a quarter
of a mile above its junction with the northern branch, and forms the
chief line of communication from the northern and central portions of
the city to the railway termini and deep-water quays on the southern
side of the river.

[Illustration: THE NEW ANGLESEA BRIDGE, CORK.]

The new swing bridge occupies the site of an older structure which had
been found inadequate to the requirements of the heavy and increasing
traffic, and the foundations of the old piers having fallen into an
insecure condition, the construction of a new opening bridge was taken
in hand jointly by the Corporation and Harbor Commissioners of Cork.

The new bridge, which has recently been completed, is of a somewhat
novel design, and the arrangement of the swing-span in particular
presents some original and interesting features, which appear to have
been dictated by a careful consideration of the existing local
conditions and requirements.

On each side of the river, both above and below the bridge, the quays
are ordinarily lined with vessels berthed alongside each of the quays,
and as the river is rather narrow at this point, the line of fairway for
vessels passing through the bridge is confined nearly to the center of
the river. This consideration, together with some others connected with
the proposed future deepening of the fairway, rendered it very desirable
to locate the opening span nearly in the center of the river, as shown
in the general plan of the situation, which we publish herewith. At the
same time it was necessary to avoid any encroachment upon the width of
the existing quays, which form important lines of communication for
vehicular and passenger traffic along each side of the river, and to and
from the railway stations. Again, it was necessary to preserve the full
existing width of waterway in the river itself, which
