There's a bridge in Overtown, under the 836 Expressway, that has long sheltered homeless people, many of whom are addicted to heroin.

Now a public health investigation is looking into a group of new HIV cases there. That’s part of what prompted Miami city commissioners to pass an emergency resolution to close the street two weeks ago.

A couple of sets of barricades block traffic to the area. Cars can't get through, but people are still staying there.
