- Role: subject
- In the article: I-95 was originally to cross Baltimore Harbor on a double-deck bridge from Fort McHenry to Lazaretto Point, but the bridge would have had to be very high for large ships. The planners instead went under the harbor with a prefabricated immersed tube tunnel, which the video uses as its opening example.
- Why it matters: It is the motivating case for the video’s explanation of immersed tube tunneling; the rest is general method.
