You would divert them to some surface streets like 15, 1, 301, 66. You'd ensure they not use 95 by putting up a sign on the onramp that says road closed and you'd leave it unplowed while you focused your efforts on keeping other routes clear. Many trucks would probably just lay up at a gas station.

Are you familiar with the area? I’ve been here since ‘89. Those streets cannot handle the volume of traffic we’re talking about. There aren’t enough gas stations for the truck volume we’re talking about either.

There simply wouldn't be the normal volume of traffic on the roads if that interstate was closed. People would call off work and not drive to schools. The local roads will do fine with the remainder of people who absolutely cannot get off work during a blizzard, probably emergency workers. Plenty of major interstates that see huge volumes of traffic endure closures and the local community just responds accordingly.
