On 13th September 2004 Waterways Ireland issued a notice
entitled "TEMPORARY NAVIGATION CLOSURE SPENCER DOCK, ROYAL CANAL,
DUBLIN"
Waterways Ireland proposes to prohibit navigation at the
above location in accordance with Bye-Law 18 (1) of the Canals
Act, 1986 (Bye-Laws), 1988, for the period commencing 4th October
2004 to the 1st May 2005. This closure is required for the
following purposes:
- to put in place emergency flood protection measures for
the East Wall Area;
- to undertake site investigation and survey works.
On 25th April, 2005 Marine Notice #6 of 2005 extended this
closure to 2006. It was again extended by Marine Notice '7
of 2006 to May 2007. This notice was modified in late
2007/early 2008 to have an end date of 31s May 2008.
We note a DDDA
press release from
23-08-2005 that said "After many years, the juncture of the
Royal Canal and the River Liffey will again be navigable with the
announcement of a project to restore the Spencer Dock sea lock in
Dublin's Docklands"
On 11 August 2005 (a full year
after the closure) we noted in the Irish Times that "Dublin City
Council seeking expressions of interest from contractors to
restore the sea-lock at Spencer Dock and install flood defences."
Marine Notice 2006#7: extended the closure at Spencer Dock until May
2007.
In November 2007, work has finally begun on
the seaward lock of Spencer Dock, with work due to start on the
landward lock shortly. Work has also begun
on re-excavating Spencer Dock to its original dimensions.
The picture at right (taken 10/02/08) shows
where a section of the channel just north of the Scherzer bridges
on the quay has been cut away to allow for placement of the
Sector Gates. The beautifully curved stonework of the channel is also
apparent from the photo.
The original sea locks were located under
the Scherzer bridges. The landward locks are 53m upstream.
The new design sees the original locks replaced with a set of
Sector Gates. Sector Gates can handle scenarios where the head of
water is either side of the gates and are frequently used where
canals or marinas encounter tidal waters such as the Liffey.
The project is due for completion at the end of 2008.
The picture below shows the first of the
gates being swung into place.

The photo at right shows the new sea locks
in situ on 16/08/08
Construction of the International Convention Centre started Monday 19/11/07.
