"Is this the Golden Gate?"
"I had an etching right there of the Capitol before it was finished."
"Took 85 years to complete it."
"How long did it take to complete the bridge?"
"Uh, about four years. It opened a few months after FDR's second inaugural."

What I confused is this sentence. "I had an etching right there of the Capitol before it was finished." What is the meaning of this sentence? And does the Capitol took 85 years to be completed?
I will be very grateful if someone explains it to me. Thank you.
