Street closings will probably be posted on the DOT's website, probably right after Labor Day (they do one week at a time)

The VMA's are a minor event in the city, I would not expect any huge issues, just diversions around any of the areas they are using throughout the city. In many cases, it will probably be a lane or two that's closed for the limos to drop off and pick up, but other lanes will still be open.
