Exit 0. How often is there one?

[PurdueBill]

Louisiana typically uses blank exits instead of 0's. I know that 210, 310 and maybe 110 are blank at their termini with I-10. 220 is a funny one. One exit before 20 is 1A, the I-20 exits are 1B and 1C, and then after the change to LA 3132, the exit is 1D and then they ascend again.

Not 110. The termini exits are marked as 1I and 1J.

Not to mention that the order of exits is I/J, A, B, C...

So approaching the end of the route, exits go 1C, 1B, 1A, 1I-J.  If ever there were a place for Exit 0.....

(And why would they have chosen 1I? If they used Exit 0, would they have suffixed it to be Exit 0O or something?)

Has it always been suffixed that way at I-10?  And Purdue Bill, the number 1 exits go from 1A to 1H going northbound on 110, so I and J weren't just picked at random

But why use I that looks like a numeral, and why go out of order with the highest letters before A?  It would have been better to either use zero or not number at all.

oh no, I totally agree with you. I think it needs zero or blank exit

The ramps for Interstate 10 were assigned exit numbers (1I, 1J) in 2003 during a sign replacement project. Before that, they were unnumbered.

Wisconsin uses exit 1 where applicable. Some routes (I-39, US 45 & 53) start a higher numbers due to where the highway enters/starts.

Every other weekend.

There are two Exit 0's I can think of.

PA: PA Turnpike 66 at I-70/US 119
WV: I-70 at Wheeling Island

The southern-most exit on the Garden State Parkway in Lower Township, NJ is Exit 0.

Didn't see this mentioned here or on the newer thread. I-94's western terminus near Billings, MT has an exit 0 to eastbound I-90, while continuing straight leads to I-90 westbound: https://www.google.com/maps/@45.832636,-108.388216,3a,75y,215.58h,93.13t/data=!3m4!1e1!3m2!1sR1g6li-0sGPiCY8Fnla_7A!2e0
