It looks like Hurricane Matthew is going to run up the US east coast like a buzz-saw from Florida to South Carolina: http://www.bbc.com/news/world-us-canada-37571685 If you're curious about what a one-way expressway (motorway) looks like, check out the traffic cameras along route I-26 between Charleston and Columbia SC: http://www.sc511.org/ (You might have to click on a few before you find one that responds.) The eastbound lanes have been reversed so that all lanes now flow away from Charleston. This will continue until sometime tomorrow (Friday). As I write this, traffic actually looks rather light in the reversed lanes. This probably has to do with the fact that drivers can't exit anywhere along those lanes. If you enter them at I-526 in Charleston, you have to stay on them until I-77 just south of Columbia. Fortunately, I'm far enough away from the coast (well past Columbia) that our weather forecast calls for only some rain showers and wind (max ~20 mph) from tonight through Saturday afternoon.
