If you drive on I-75 through Saginaw County, you've probably seen these huge piles of broken up pavement.
But what, if anything, are they being used for? The answer might surprise you.
A temporary recycling facility has been set-up in the middle of two of Saginaw County's busiest expressways, I-75 and the northbound ramp to I-675. The Michigan Department of Transportation is removing concrete on I-75 for a resurfacing project.
Instead of throwing it out, they are stock piling it. That concrete is ground up to be used as a base for the new road.
MDOT started recycling old roadways several years ago to reduce waste and to drive down costs. Without the onsite recycling, thousands of expensive truckloads of materials would have to be hauled in, which also lengthens the time it takes to complete the project.
The project will take the rest of the summer and is expected to be completed this fall.
In November, MDOT says everything from the equipment to the rock piles will be back to normal, looking just like it did when they started.
MDOT says recycling old roadways can save taxpayers millions on a single project.
