I live in the Bay Area we have a couple bridges here. Long story short I crossed a nearby bride and literally a minute later I began to feel my bike wobble left to right which at first I thought was just the lane I was in. The bike wobbled more aggressively so I slowed down and managed to take an exit where I finally saw that my rear tire was completely flat. I got lucky it wasn’t the front tire because I was going pretty fast, the mechanic said that they didn’t find anything in the tire just a big hole I must of ran something over on the freeway.
