The largest tree root.
This is the largest tree root removed. It had penetrated deep into the bridge.
It would have been necessary to dismantle the whole bridge to remove all the roots. The smaller ones have been left in the structure. Evenutually they will decay. The lime mortar will allow a cerain amount of movement without cracking so we do not expect any problems.
Pat Irwin, the Project Manager is on the left and Pat Finucane, restoration mason is on the right. They are debating how to remove the stones that are still entangled in the roots.
A ring count showed that the tree had been growing there for over 40 years. . . . since about 1972.
If ever there was an example of "A stitch in time saves nine", this is it!
