Always been a fan of AAroads.com but for whatever reason never joined the forum. I am a huge fan of roads, signs and infrastructure in general. One of my favorite topics is concurrent roads that are "going" in the opposite cardinal direction. I am originally from Kentucky and in Kenton County State Route 16 and State Route 2043 run concurrent for about 1 mile and KY16 is signed as going South and KY2043 is signed as going North. It makes sense when you look on a map but it is always funny to see something signed that way, I just wish I had taken a picture before I moved to Florida!
In Newport News US 60 eastbound and US 60 westbound go the same direction on the same road (there are a couple other cases like this but this one is the best-signed). Different route opposite-direction overlaps have nothing on it.
Welcome to the forum, hope you find it as helpful as the main AARoads page.
