Starting tomorrow (Saturday!), nearly seven miles of NYC roadways are closed to vehicles for people to run, walk, bike, complain that this makes double parking nearly impossible, etc.
As in previous years, this car-free zone includes Lafayette, Astor Place and Fourth Avenue from 7 a.m. to 1 p.m.
You can find more details about Summer Streets at this link, including the sponsors and free exercise classes on Astor Place.
