Since there's no possible expansion of the Holland Tunnel or Lincoln Tunnel, expanding the turnpike just creates bigger traffic jams in Jersey City. Manhattan can only contain so many vehicles anyway. Better mass transit is the way to go. The new rail tunnel is finally being built . Christie canceled ARC 12 years ago in one of the most shortsighted decisions ever. That tunnel would be done now. The new one won't be done until the mid 2030s. The current tunnels are over 100 years old and were damaged by Hurricane Sandy, if one or both fail no new highway will be able to take the traffic into New York. I personally believe the best short term solution is more ferries from varied locations in New Jersey. Not a perfect idea but a good way to take stress off roads and train lines.
