State Route Oddities

[jemacedo9]

What are some of the oddities of your state route system?  For example, things like state routes that don't end at other routes (not counting borders), or have multiple separate sections.

In PA:
1.  There are two separate PA 29s, PA 97s, and PA 272s
(PA 29 used to be one route where the middle became US, then PA 309)
(PA 97 in South Central PA used to be US 140, when that was decomissioned, MD replaced that with MD 97 and PA matched the numbering)
(PA 272 looks like a secret multiplex with US 222 through Lancaster City but last time I was there, PA 272 wasn't signed)


There are a few state routes that do not end at another route:
PA 660 W terminus in N Central PA (ends at east rim of PA Grand Canyon)
PA 56 W terminus ends at Allegheny River Br
PA 114 S terminus ends at Old York Rd in New Cumberland
PA 441 N terminus ends at Paxton St in Harrisburg
PA 324 S terminus ends at Susquehanna River
PA 533 W terminus in Cumberland County

There are a few cases where two state routes end at each other (and neither route continues):
PA 49 E terminus and PA 287 N terminus in N Central PA
PA 181 N terminus and PA 382 E terminus in York County
PA 441 S terminus and PA 999 W terminus in western Lancaster County

And finally...US 209's western terminus is PA 147 in Millersburg...maps may show that US 209 crosses the Susquehanna River and then ends at US 11/15, but the approaches to the ferry on either side are not marked.

CT's SSR 403 is one-way, yet has a double-decked section. (This becomes much less mysterious when I add that the lower level is for arrivals, upper for departures :-))

California has plenty of examples of this.  CA-84 is in several segments, making it next to useless for navigational purposes between the Dumbarton Bridge and Sacramento (then again, if you're taking that, instead of 680 to 80, to Sacramento, you're clearly looking for adventure).

CA-173 is the only dirt road segment in the system, and it is appallingly bad, even by dirt-road standards.

M 185 is the only motorless highway in the usa also M-147 is know as "it's ... the second shortest highway on Michigan's state highway system, but for those who travel it one way, M-147 is the longest road in the world" as it terminates in the Jackson State correctional facility

[ftballfan]

M-185 does not allow cars. Also, it and M-154 are the only two state highways in Michigan that are completely on islands.

Florida's weirdos:

SR 9336 - Not sure how or why they came up with that number, it dead-ends at Everglades National Park (a good reason, at least).
SR 17 (and CR 17) - exists in about 10 pieces, and alternates.
Some of them are less than a mile in length: SR 844, 849, 970 for example.
There's also the unsigned diagonal routes like 500, 600, and 700 that are tricky to complete.
Also plenty of "look-it's-a-county-road, now it's a state-road, no wait...it's a county road again" examples: SR 15, 884, et cetera.
Lots of maps show county roads as state roads, just collect 'em all!

CA-65 and CA-271 have two completely different segments that are not connected. Not sure if plans exist to actually connect them or not.

While others, such as CA-168, CA-178 and CA-190 (among a few others) have non-continous segments with implied connections through either the Sierra or Death Valley, and thus are virtually impossible to truly unite.

Then there are some routes like CA-14 which are north-south, despite even-numbered routes generally running east-west.

And lastly, there are multiple segments of CA-1 that are concurrent with US-101 but not signed, making it hard to navigate at times.

PA 283 is internally known as PA 300 and PA 380 is internally known as PA 400 because of the interstates in the state with the same number.

CA-65 and CA-271 have two completely different segments that are not connected. Not sure if plans exist to actually connect them or not.

The 65 gap has been on the long-term plan for decades, 271 on the other hand was assigned to two separate sections of former US 101 with an implied concurrency with existing 101 (but no signs).

While others, such as CA-168, CA-178 and CA-190 (among a few others) have non-continous segments with implied connections through either the Sierra or Death Valley, and thus are virtually impossible to truly unite.

The trans-Sierra crossings were planned at one point though.  I'm surprised those roads didn't get redesignated once it became clear they weren't going to happen.

Nevada:

* A few urban state routes that are in discontinuous sections.
* A few extremely short urban state routes (i.e. less than half a mile)
* At least two state highways that do not connect to the rest of the state system: SR 705 and SR 513 (caused by the recent decommissioning of part of SR 529/Carson Street in Carson City).
* Unless it's already a state-maintained route, the portion of practically any road between the ramps at any freeway interchange is classified as a frontage road with its own frontage road number, despite not actually being a frontage road.

Then there are some routes like CA-14 which are north-south, despite even-numbered routes generally running east-west.

Along those lines, CA-82/El Camino Real is north-south even though it's a even numbered route and CA-237 is east-west.

The ex-Route 9 state highways (236, 237, 238 formed in 1963-1964, 262 in 1965 due to the 680 rerouting) ALL seem to have odd numberings relative to the actual route direction!

Also in that vein is Route 70, which is north-south for its first third in length along former Route 24 and US 99E/Alt US 40.

Indiana:

IN 1 has two segments
IN 4 has three segments
IN 47 is mostly east-west but has an odd number and is signed as north-south
IN 75 has two segments
IN 101 has four segments
IN 114 has three segments
IN 121 has two segments
IN 520 is 0.3 miles long
IN 912 has two segments

Part of MN-23 goes through Wisconsin.

There are two separate, completely unrelated MN-62s.

[apeman33]

There are two K-8's, both very short, separated in the extreme northern and southern parts of Kansas because the part in between became U.S. 281. The southern K-8 was renumbered for a while but eventually was changed back to K-8.

There are also two K-171's but they were never connected. The southeastern K-171 was changed when K-57 was truncated with the new number matching the Missouri segment, 171 (which at one time was itself MO 57). There wasn't really a reason the change the K-171 in Smith County. It's just a short spur serving a small town.

K-150 was also in two parts until the portion in Johnson County became entirely within city limits and was turned back over to the cities it ran through.

And, like several others here, I've driven on the road that is both OK-20 and AR-43.

There are two separate, completely unrelated MN-62s.

And the WI part of MN 23 uses a Minnesota shield in WI.

Coming off the Walt Whitman Bridge from PA to NJ, the first exit uses PA's exit numbering scheme, making it Exit 354.  This is by far the highest exit number in NJ, considering that the longest highway in the state is only 172 miles.

Part of Texas 87 was wiped out in the hurricane and has not been fixed.  That was the 1980 hurricane.  So the eastern part and western parts dont connect, yet if youre heading eastbound on the western segment, it turns north and changes numbers.

El Paso has the short segments of US-62 (meaningless duplex with US-180 for hundreds of miles) and US-85 (unsigned thru CO & NM)

[Quillz]

Speaking of natural disasters, mudslides are the reason CA 39 and CA 144 do not connect to CA 2 and CA 192, respectively. The former is supposed to be reconnected soon, not sure if the 144 will ever be fixed.

Hurricane Jerry in 1989, not 1980. TX 87 was closed in 1990 after Jerry did that job.

PA 82 was a victim of Mother Nature as well when it became a divided route after Hurricane Agnes in 1972 washed away three bridges.

It wasn't until 2008 that the problem was rectified when the route was truncated to PA 23.

Just make TX-87 west of the hurricane closure an extension of TX-124, which is what TX-87 turns into at the eastern end of the western segment.

It doesn't look like the mudslide area on CA-144 is that large.

[US71]

Arkansas has lots of non-continuous routes (begin, end, begin again...), many of which "end" at a county road.

A couple of the worst offenders are AR 74 and AR 60

Or better yet, fix it

NJ 440 exists in two segments on either end of Staten Island, yet are signed in opposing cardinal direction pairs.
