That sort of thing happens frequently here, not the trucks blowing over so often but the deal with cars being blown into the other lane and great difficulty diving during wind storms and camper shells blow off pickup trucks. It gets pretty scarey at times. This bridge is on US 101 and is pretty close to the Pacific ocean. There is nothing to block the winds from the ocean there and it is very common to have wind gusts in excess of 60mph during winter. The gusts are not once in a while but nearly continuous when it gets bad, like boom boom boom one right after the other. Several years ago there was a huge wind storm with gusts like that over 80mp and in Newport (where I now live) and the roof completely blew off of Izzy's Pizza located on a hill almost right at the shore. Everyone started calling it Wazzi's Pizza after that for about a year until they rebuilt it. A lot of buildings were damaged that year and power outages for days and even weeks in some areas. Lots of trees to get blown over.
