Map Showing Possible Future Flood Depths in Mobile, AL, with Rising Sea Level

Transportation systems in many coastal areas in the United States are vulnerable to the impacts of sea level rise. This map shows that many parts of Mobile, Alabama—including critical roads, rail lines, and pipelines—would be exposed to storm surge under a scenario of a 30-inch sea level rise combined with a major hurricane. Click the image for a larger view.

Not all roads would be flooded if they merely run through low areas since some are built above flood levels. A 30-inch sea level rise scenario is within the range projected for global sea level rise. Figure source: U.S. Department of Transportation 2012.
