Arch Superintendent: Rust ‘Purely Cosmetic’

ST. LOUIS (KMOX) – Politicians broke ground last week on a project to improve access to the Gateway Arch, but what about rust that has lingered on the monument for years?

Arch Superintendent Tom Bradley says officials are preparing to clean some rust-colored marks on the north leg.

“As you can see, there is some staining and we’ve pretty much narrowed that down to the wells tracking dirt. It’s purely cosmetic. It’s completely dry inside as far as there’s no water intrusion,” he explains.

Earlier reports had warned about corrosion found inside the Arch. According to Bradley, that rust is “no longer active,” and is now under control after officials took steps to control humidity.

“The next phase will be getting someone out on top and repelling down to take actual samples and then start doing some cleaning regimen to see what’s going to work before we go back and do it all together,” he added.

Bradley says that while there isn’t an owner’s manual for something like the Arch, it is in “excellent shape” and should last “another hundred years.”
