close to the question
...That method in vogue in Detroit brings us close to the question of the system of the municipality doing its own contracting; this is practical, not only in the matter of pavements, but in every class or work. If it is possible for a contractor to build a pavement and make a profit, the city can do the same thing — and the profits set aside for maintenance purposes. The city can legally have a plant to repair its asphalt, brick and other pavements; can do the patching and puttering around, but it is dreadfully illegal to undertake new work.
This brings us to the question of repavement.
