How do we make sure that poor people benefit from large scale infrastructure provision?

Another aspect of this is that in times past, at least in the United States, infrastructure has been created in ways that disrupt and cut off impoverished neighborhoods and that do not improve or replace crumbling infrastructure in poor areas.  Belts are built through and around cities that literally marginalize the poor.  I have seen crumbling bridges and roads more in impoverished places, in my city and in others. And in addition to roads and bridges, water and sewerage are infrastructure, too. We have seen what has happened in Flint, Michigan, and the problem exists in many older American cities, far more in poor neighborhoods than in wealthy ones.  The problem of the water in Rio right now is another example.  Gas and electric lines are a problem, too.  Wealthy people will often reside in areas where all the utility lines are underground, so when there is severe weather, they experience no loss of utilities, while those in poor neighborhoods lose their electric and gas because of that infrastructure problem.
