Most people treat Interstate 10 like a hallway — something you walk through as fast as possible to get somewhere else. That's a shame, because this highway is one of the most varied, surprising, and downright weird roads in the country. From the Pacific Ocean in Los Angeles to the Atlantic coast in Jacksonville, I-10 cuts across eight states and roughly 2,460 miles of terrain that swings between giant cacti, white sand dunes, cypress swamps, and Gulf Coast beaches.
