A one-ton slab of concrete fell off of Centennial Hall in Colorado Springs Friday (10/25/13). No injuries were reported.

The concrete block that fell is 3 feet wide, 10 feet long, 6 inches thick, and weighs more than 2,000 pounds.

El Paso County Commissioners tell KRDO NewsChannel 13's Olivia Wilmsen that the slab is more than 30 years old and they believe the steel that held it up was corroded. A structural engineer will make the final determination about why the slab fell.

Centennial Hall is owned by El Paso County and was built in 1976. The complex is home to several county offices, including the Board of County Commissioners. The area where the slab fell is home to the El Paso County Clerk and Recorders office.
