McCOOK, Ill. -- It takes 38,000 tons of stone to build just one mile-long lane of an expressway. So where does all that stone come from? Quarries.
In this week’s “Seen From SkyCam” segment, Sarah Jindra took us to a local quarry to see how the stone for our roads is produced.
When SkyCam9 flew above I-55 to look at the traffic, it saw just east of LaGrange Road a huge hole in the ground just north of the expressway -- and another one to the south.
Welcome to McCook Quarry, one of the quarries in the area that makes the stone used to build our roads.
This week Jindra went down to the quarry and talked with one of the companies that operates here, to learn more about what’s happening down below.
