It was a rough commute for drivers across the Centennial Bridge this morning. And we wanted to know why the ice wasn't taken care of. We found out the Illinois-DOT is responsible for salting and sanding the Centennial bridge.     

"The bridges do freeze faster than the roadway," said John Wegmeyer, Project Implementation Engineer District 2 of the Illinois-DOT.

He says they always take special care of bridges because they freeze so fast. He says they brined and salted.
     
So why did it freeze? Wegmeyer blames a couple of things. 

"I think the magic number is like 15 degrees and below that then you know salt, unless you pour on an awful lot of salt, it's not going to be very effective," said Wegmeyer. "Well generally the salt works I most conditions, we don't have sand supplies available to do like that. and we do use grit and things. We've used a lot of experimental things too to try and keep the bridges as safe as possible. We just didn't have that available today."

He says crews were too far away, so they couldn't get sand on the bridge until 7 AM. And he also blames the drivers.

"With the Centennial Bridge is because it's so long and there are no traffic lights and intersections in between, people tend to drive faster than they do on regular streets," said Wegmeyer.
