It’s hard to go the speed limit in Cumberland. Entering the town, (it doesn’t matter if you’re headed eastbound or westbound) you’ll be going downhill and will have a nice 65 mph speed limit. However, within a few miles it’ll reduce all the way down to 40! This might be the worst designed stretch of interstate ever. It’s jammed in between the buildings in crowded Cumberland, and has lots of slow curves and exits that sneak up on you. Go the speed limit so you don’t get a ticket (there are plenty of cops), but don’t get rear ended.
