If you have any appointments or anything you have to be strictly on time for you should probably go ahead and reschedule that right about now. If you live inside the loop, you should plan on staying inside the loop until at least 2pm and the later the better. If you want to drive anywhere near the course, inside or out, just don’t bother. If you need to sneak through by bicycle or on foot, that is usually possible. The MTA hasn’t made any announcements about transit during the race because of course they haven’t. They are terrible.
Last year I had to
abandon park my car in a completely different neighborhood then go back & get it because traffic wasn’t moving and I had a date. Thankfully, the date was nice enough to walk back with me later but yes, plan ahead!
