Adding lanes to a freeway does nothing to speed traffic. Shutting off exits would speed it up more.Limited access highways are needed and toll roads fill that need. Houston has greatly improved it's traffic flow in the past 15 years by the tollroads on the beltway.

That depends on how entrance/exit ramps are designed. The entrance/exit ramps on I-35 between Austin and Hillsborough are atrocious and very dangerous with very short and abrupt merges from the access roads to the freeway. I-37 has much better ramps

I am all for a new highway system. We have pulled a travel trailer all over the U.S. for the better part of 30 years. It is a real bear having to just drive through a city when all you are doing is passing through. We know that it's going to take us at least an extra hour and a half, especially around rush hour. This trans-traffic thing will probably be a big hit with all the semi-truckers and travel-trailers.
