This isn't a global warming story. This is a Keys corruption story. Here are typical road costs in Florida: https://www.fdot.gov/programmanagement/estimates/lre/costpermilemodels/cpmsummary.shtm https://www.fdot.gov/programmanagement/estimates/lre/costper... . Note that $25 million per mile is much larger than the cost to build a new 6 lane urban interstate. Yes, it does cost more to build on the islands. From the experience of building my dad's house in the Keys, things tend to cost about 4 times as much as on the mainland. Most of that is due to theft and embezzlement, such as https://www.miamiherald.com/news/local/community/florida-keys/article238036829.html https://www.miamiherald.com/news/local/community/florida-key.... This stuff is very, very common, as in "just happened to my dad last Saturday" common. I'm not sure if the county is just creating a high price as just a way of justifying a "no", or if they are taking into account the actual cost of building including all the corruption.
