Forgotten Exit Numbers

[roadman65]

I noticed in NJ on NJ 18 Southbound on its freeway section all exits in Monmouth County have exit numbers but one southbound ramp.  The exit for Morganville which connects to Tennent Road lacks an exit number.

All exit ramps for NJ 18 in Monmouth County have numbers but this one ramp. Any other freeways where one ramp is overlooked for an Exit Number while the rest have them?

CT 15 near MP 63 (between Exits 66 and 67).  The RIRO ramps that are designated for the CTDOT maintenance are often used as secret ramps to Murdock Ave and a backdoor way to get to the industrial park on Research Parkway.

There also used to be a ramp from Bina Ave to I-91 North in Windsor that was eliminated around the time the I-291 interchange was built that didn't correspond to any exit.
