| 摘要： | The Mississippi River Ship Channel Deepening to 50 Feet Project has shed a unique light on the importance of our transportation infrastructure and what I refer to as "invisible infrastructure." Defining the term "invisible infrastructure" is complex. Sometimes components of our invisible infrastructure are clearly visible, yet they are completely overlooked until they fail. Then, in an instant, the whole world is focused upon them. For example, consider the power lines that closed the Mississippi River Ship Channel when they were knocked down in Hurricane Ida. Thousands of ships passed under those lines each year, but no one thought much of them until they fell and closed the ship channel. As a nation, we speak a lot about physical infrastructure, while often overlooking critical components like invisible infrastructure. Invisible infrastructure also includes things like air gap sensors, sediment, pipelines, navigation technology, aids to navigation, current meters, fog sensors and, perhaps the hardest to understand, geodetic datums. |
