I wasn't sure what to put this idea in, so just decided to dump it in general. List and describe any limited access highways, interstate or not, that you feel takes a weird or random route that doesn't make much sense, or doesn't serve any useful purpose in your opinion. A highway that takes a very weird path, such as almost looping back on itself despite not being a beltway, or just ends unexpectedly in the middle of nowhere.
Example: I-278 in NYC
This "interstate" is just a bunch of different roads slopped together in the same designation. It is not a beltway, yet zigzags through every borough of the city. It constantly changes direction, at some points almost doing 180s on itself. It is designated an East-West highway despite being generally north-south for the most part. It ends in 78 despite not connecting to I 78 in anyway, directly or indirectly. It is extremely congested, has a 45 mph speed limit, it sneaks into NJ for 2 miles without continuing to another major highway (like I 78 for example) many exits are not accessible from both sides and just is a nuisance road overall, any highways in your area you feel similar about? What roads do you think are weird routes?
