2:43 pm. One hour and 16 miles later (I checked on Google maps), we’re safe at the truck stop. A DOT worker told us that smoke from a grass fire made it necessary to close the interstate due to poor visibility. He said that no one had been there to direct traffic and it was a dangerous situation to have 18-wheelers using those old bridges. That’s why the police car finally came rushing down when they realized what had happened. It was 108 degrees, too.
