Digging up city streets in Milan is an elegant process.
First there’s Milan.
Right?
Then the stones are removed and abandoned tram tracks can be excavated.
Groups of paving stones are numbered.
The stones are returned to the same strip from where they came.
Then they are watered and sand is washed into the cracks and voids under the paver.
A few weeks later and the dried repair is hard to even notice.
