Many coastal areas in the United States, including the Gulf Coast, are especially vulnerable to sea level rise impacts on transportation systems.8dbd70c4-cd8c-4dce-b27c-bfb412901e58^,1bc74f07-688c-482c-a923-483f5d3de8b5^,0127c256-83e6-4e22-9715-bfc0fbbfb8d9 This is particularly true when one considers the interaction among sea level rise, wave action, and local geology.5ddaab38-f315-487d-8b7a-bb322bb9b60c 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 storm similar to Hurricane Katrina. 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 (Ch. 2: Our Changing Climate, Key Message 10). (Figure source: U.S. Department of Transportation 2012
