The bridge dates to 1924, and is listed on the National Register of Historic Places.
The TV station had a few details about the repairs:
The nearly two year restoration included keeping the bridge’s original look. Officials said the weathering steel was used to keep the bridge historic. The steel will begin to rust quickly in humidity and forms a protective layer over the bridge.
“It makes the new steel match the old so quickly that it’s hard to tell where the new steel was installed,” Clowers said.
City officials said each bridge section to be replaced had to be removed, measured and exactly reproduced by the fabricator.
The bridge also was mentioned in John Steinbeck’s novel, “The Grapes of Wrath.”
UPDATE: The City of Oklahoma City sent this great photo from the bridge earlier today.
