Touring the NAFTA Super Highway
As I toured hundreds of miles of I-35 through Missouri and Iowa, the construction could not possibly have gone unnoticed. The fact that they were completely ripping up a concrete road to replace it with another concrete road quickly got my attention. Isn’t concrete supposed to last 50+ years? Most of I-35 was built in the mid to late 1960’s, so at 40+ years old could it have really needed this?
As I observe, they first drive a very large piece of equipment over the road with a jack-hammer effect and leave the road in ruin. Next, they drag through the rubble to pull out all the rebar, and then they crush the concrete even further until they eventually get it down to stone size. Finally, they dump the stone-size pieces of concrete into a machine which grinds it down to sand. The 10” to 12” thick concrete road is then replaced with another 10” to 12” thick concrete road.
Supposedly, one of the advantages to concrete is that it will last a very long time and is easy to repair. According to the ACPA (American Concrete Pavement Association):
“Restoration techniques can extend the life of concrete pavements up to nine times their original design life.”
So again, did this 40+ year old road really need this extreme replacement?
A couple of other interesting facts about concrete from the ACPA:
“Concrete can best withstand the heaviest traffic loads. There’s no need to worry about ruts, shoving or washboard effects possible with asphalt pavements.”
“Make it unnecessary to impose weight restrictions during the spring thaw. The U.S. trucking industry would be more profitable, more efficient and more competitive. Seasonal restrictions now cost approximately $50 million annually.”
Maybe it should say, “The Mexican trucking industry would be more profitable.” Just sayin’.
Now supposedly, the NAFTA Super Highway is going to be four football fields wide and parallel to I-35. Well, it’s not. This is how they work, blending enough fact with fiction to confuse the masses. While people are looking for such a wide highway to be built, the actual construction is ongoing. Just think about it!! Imagine a highway that wide (eight lanes), then imagine the amount of traffic it would take to fill it up for more than 1500 miles. I would bet, you could put every 18-wheeler in this country on a road like that at the same time and traffic would still flow. A normal four-lane highway will sufficiently handle the traffic to and from Mexico and Canada through most of this country. It would naturally have to be wider near cities to handle local traffic, but the “Super” Highway does NOT have to be all that “super” to accomplish the mission.
They seem to be moving rapidly on this construction project as much of what we were driving on had been completed and they are working seven days a week. The above photo of construction was taken on a Sunday.
My tour for hundreds of miles up and down this highway had pretty much the same scenery; cornfields. Traffic was nothing compared to our South Carolina highways and the I-35 unrepaired sections were not as bad as much of ours up and down I-26 and I-95. Why does federal funding exist for these highways in the middle of nowhere, but not our highly traveled east coast roads? I believe we all know the answer to that at this point…
