Discontinuous segments of signed, numbered routes

[jemacedo9]

One of the more notable examples is US 422, which disappears westbound (ends, according to signage) in Hershey, PA and likewise eastbound in Ebensburg, PA.

Some evidence suggests that PennDOT internally considers US 422 to be continuous (a long, unsigned overlap with US 322 and 22) despite the END signs at either end.

Agreed.  I kinda like PA 622 as a number...though that would reduce US route mileage in PA.

Ohio has two SR 152s in Jefferson and Harrison counties. They used to be continuous but the middle section was deleted in the 1940s. It's been a couple years since I checked, but ODOT's destape route log used to explain the gap as "temporary."

Virginia has multiple sections of SR 42 that lie between the WV line and the Great Valley. Some used to be connected, others not.

You also have VA 259, which exists in two segments connected by WV 259. There are two sections each of WV 311 and VA 311, with the other state's version in between.

Mississippi has a number of discontinuous highways, like MS 149, and US 51, which disappeared through Hinds County.

Arkansas is really bad about discontinuous routes, including hiding US Highways along the Interstate (ala Colorado).

Indiana State Road 8 is one.  It has two completely different segments, most likely to fill a grid in the state's overall road system.

Washington State Route 501 near Vancouver, WA is one. The gap is in a national wildlife refuge and will hopefully never be completed.

Louisiana has LA 120 and another one that I cannot remember for the life of me. I'm not sure if 120 was ever meant to be signed on the middle section. It's a terrible road and would take a lot to get upgraded to standard.

I was thinking that the two disconnected segments of FL 84 might qualify, given Florida's hidden state highway designations along I- and US- routes, but apparently Alligator Alley shares the hidden FL 93 designation with the rest of I-75.

Oh, trust me. FL 84 is not the only one. You've got plenty of them in the Tampa Bay Metro Area, but most of those gaps are filled with County Roads (54, 582, 586, and others).

NY 24, NY 42, and even NJ used to have them as NJ 20 used to be in three segments not connected.  NJ 38 was in two with NJ 138 being its easternmost segment at one time.

Yes Florida has plenty as said earlier, including SR 20 and SR 200.  Both are actually continuous, but not signed as SR 20 is silent with US 441 and US 27 between Gainesville and Tallahassee, and SR 200 silent with US 301 between Ocala and Callahan.  Nonetheless not signed and falls into the category of signed numbered routes.

Florida has quite a few unsigned multiplexes... They are signed as completely different sections.. In Clay County where I live SR 224 ends at SR 21.. Four miles later CR 224 turns off.. At once point many of the CR were secondary state highways.. CR 315 uses SR21 to connect sections.. Clay County even signs the southern part as CR 315c.. Putnam just calls it 315
