DETROIT — Officials say they don’t know when the two-mile section of I-75 between Detroit and Flint will be re-opened, following the gas-truck explosion that ripped down an overpass late last week. 

The crash, involving a tanker carrying gasoline, another tractor-trailer loaded with groceries; and a Honda Civic, took place early Thursday morning. Amazingly, only one of the three drivers was injured, and he only had a few bruises.

Otherwise, the only damage was to the vehicles, the overpass, and the surface of I-75.

Michigan officials told media that they have no idea how long it will take to clean up the mess. So in the meantime, drivers will be directed to alternative routes that include the Lodge Freeway and surface streets including Woodward, Dequindre, John R and other nearby north-south routes.

The detour might also push traffic on to I-94 and into the east side suburbs of Detroit.

Meanwhile, a bridge overpass burned is a lesson learned, say says the American Trucking Associations (ATA).

The trucking group lost no time using the dramatic collision as a platform in its "educate the four-wheelers-of-the-world" campaign.

ATA’s Foundation for Traffic Safety stated the crash “underscores the need for more automobile driver education.”

Studies show that between 65 and 80 percent of serious truck-car crashes are caused by the passenger vehicle, and that’s what happened in Detroit.

ATA drew attention to a project it calls the Ticketing Aggressive Cars and Trucks (TACT) program, which is designed to do exactly what the name implies. Teach four-wheelers how to drive and teach them a lesson when they don’t do it right.
