Part 1: Exploration and Archaeology
While much of the damaged and missing stone is being carved for the restoration of the bridge, the dam works have also been started so that the foundations and leaks are made good before the bridge structure itself is put back to its original glory.
Before work began the water level in the pond in front of the bridge did not rise to the level of the arches, where the water should flow out to create a waterfall behind. Instead it was seeping out and under the dam, potentially causing catastrophic damage to the foundations. Only during flood conditions did the water rise high enough, and then too high, creating dangers to the whole of the bridge structure itself. The concrete apron we were sure was added in the 1970’s when Mr Nataro owned the field and completed a lot of works which no doubt helped the landscape survive until the restorations could be taken up once more. What lay under this concrete apron was a mystery. Was the concrete covering an older similar in-fill that was necessary to create the dam and support the stone bridge? Or was it entirely constructed in the 1970’s and not part of the original engineering? Was it superfluous or necessary to keep the dam from crumbling and being washed down stream?
The only way to find out was to remove the broken and leaking concrete, both to locate the weaknesses and to restore the original form, if that proved possible. The condition of the above-ground bridge structure, though propped up and secured from both sides, was still highly delicate and the works needed to proceed with the greatest care to avoid unnecessary shocks and vibrations.
