I want to know the answer to the following question:
When was the very first Nanjing Yangtze River Bridge finished?
All the background I'm provided with is that "Going in the downstream direction, the Yangtze crossings in Nanjing are: Dashengguan Bridge, Line 10 Metro Tunnel, Third Bridge, Nanjing Yangtze River Tunnel, First Bridge, Second Bridge and Fourth Bridge.". Is that enough to answer the question?
Answer: no
