Buses rolled through Pueblo's historic Steel Mill Saturday.
It's all a part of the 140th anniversary celebration of the Steel Mill.
They held a celebration at the museum.
For five to ten dollars people toured the mill and historic tunnel.
"This is a special event to get to see that part of it," said Heather Thompson, Marketing and Membership Coordinator with the Steelworks Musuem. "They have closed it off. The historic tunnel, it's just fascinating. Everyone needs to do that at some point."
When it was founded 140 years ago, it was called the Colorado Fuel and Iron Company, better known locally as CF&I.
