The real issue is the tolls on the turnpike vs the free travel on surface routes. Raising the speed limit to 70 may help a little, but the fact is that already, trucks roll on the turnpike routinely at 75 mph.

Tolls also help keep the riff-raff (aka, “other drivers”) off. Provided that there are decent alternative “free” routes; the tolls reduce congestion. Less congestion, means faster travel, with fewer stops. That saves time — which, for a lot of people is money. Also, if you cut down on stops and starts; you also cut down on vehicle wear, and improve gas mileage. Those are important considerations for commercial vehicles.

The article says that the average speed for trucks is about 66 or 67. Cars, on the other hand, average well into the 70s.

Now trucks will probably be doing about 71 or 72.
