There is some empty streets in Rome, You jus't have to find them.
All Roads Lead To Rome
The Romans built roads wherever they went. Rome, the empire, spread along the roads. Using the roads implied a dependence on Rome; but avoiding them was inefficient and unmarketable.
In fact, they built the roads in such a topology that there was a road from any city to Rome, but no road connecting more than two neighboring cities directly. That way cities could not band together to resist Rome, since to go from city A to B you had to pass through the long way: through Rome!
