Society
members will be aware that the Environment Agency
made funding available for the construction and
installation of a new bridge across the entrance
of the Dry Dock opposite the Winwick Maintenance
yard. The work has now been carried out by contractors
acting for Warrington Borough Council.
The
dock lies at right angles to the canal's course
and was closed off by a pair of mitre gates and
drained at its opposite end by a simple sluice mechanism.
When the canal was in use the tow path followed
the western side of the canal at this point and
therefore needed some method to allow the haulage
teams to cross the gap leading into the dock. A
bridge was installed which spent most of its time
allowing this tow path access but when a boat needed
to use the dock the bridge would have had to have
been moved out of the way.
This
is where the problems start. Only two photographs
have been located to date which show the bridge
and neither provides any clue as to how the bridge
was moved. One has a large vertical post set into
the ground with a diagonal timber bracing it but
there is no indication of chains or wire which would
have lifted the bridge clear of the gap.
With
such a lack of information it has therefore not
been possible to duplicate the original bridge.
Instead, a standard, timber-decked bridge with metal
rails has been constructed off site, similar to
the one installed at Penketh. Work took place on
the dock entrance, casting new edges and supports
for the bridge then the bridge was delivered on
site and craned over the fence into position. One
end of the bridge is fixed to two rotating steel
pins so that it can be lifted in the same way as
a castle draw-bridge. The mechanism to do this will
be installed only when the canal is restored to
water.
Contractors
are still to paint the structure, and SCARS volunteers
are to realign the tow path and fencing which presently
seal off the dock and the bridge from public access.
Funding is available specifically for an interpretation
board then the site will become one of a number
of features of canal heritage in this area.
