Signed state routes that dead-end

[GaryV]

Michigan 37 dead ends on the Old Mission Peninusla in Grand Traverse County. 

Until it gets truncated, as MDOT proposed.

Not sure if mentioned yet, but US-41 and M-26 dead-end at Copper Harbor, and US-45 dead-ends in Ontonagon (though if it were me, I would route US-45 up to Houghton on M-26).

Actually M-26 ends in Copper Harbor but US 41 keeps going and ends at a roundabout near Mud Lake.

A few more Virginia examples that are not state-facility routes:
US 60 (Rudee inlet)
VA 171 (boat landing)
VA 173 (boat landing)
VA 180 (boat landing)
VA 204 (Nat'l Mon)
VA 205Y (Potomac River)
VA 222 (Rappahannock River)

If Military Facilities count then also VA 105, VA 206, VA 238 and VA 278.

VA 92 has a similar situation with VA 125 on one side of the old bridge

North Carolina:
US 74 (but technically not US 76)
US 117 (Port of Wilm)
US 421 (Ft Fisher)
NC 9
NC 58
NC 128
NC 136
NC 307
NC 344
NC 461

South Carolina:
SC 260

Several in Hawaii. On Kauai, HI-560 and HI-550 dead-end at Ke'e Beach and the Pu'u O Kila Lookout, respectively, and HI-583 dead-ends at Wailua Falls. I know there are some on the other islands, too.

Actually M-26 ends in Copper Harbor but US 41 keeps going and ends at a roundabout near Mud Lake.

Depends on what you mean by "dead ends".  There is a dirt road (Mandan Rd) going out of the turnaround at the end of US-41 - that road loops around back to US-41 on the other side of Copper Harbor.

And US-45 ends at an intersection with a local street in Ontonagon.  That street used to be M-64 until the new bridge was built a bit upstream.  But it's still an intersection, not a cul de sac.

There's also MN 172, which was formerly MN 72 until that route got realigned onto a border crossing.

[Hot Rod Hootenanny]

PA 660 dead-ends at a parking area for Leonard Harrison State Park. Google Maps seems to suggest that the parking area is PA 660–and that the route therefore loops back onto itself (which perhaps is debatable as to being a dead end or not), but that doesn't appear to be supported by the corresponding PennDOT straight line diagram (bottom of page 130).

Having visited Leonard Harrison state park, last fall, coming back from the Newburyport meet, I can tell you that it is a hard no on PA 660 getting signed at the park entrance. In fact the 'End' sign for 660 is about 1/2 mile down the road from said park entrance.

On Hawaii's Big Island, HI 130 ends in Kalapana, where volcano goddess Madame Pele rudely truncated the route. However, there is a restricted-access unpaved road within the old ROW, for the remaining local residents and occasional lava viewing opportunities, and also to connect to a recently-built one-lane road reserved for emergency evacuations.

Maui's HI 360 dead-ends at the Hana Bay wharf. The turn down to the wharf was unmarked last I was there, confusing tourists trying to clinch the route.

On Oahu, HI 93 and HI 930 both end near Kaena Point. Motorists once could drive around the point between those present-day routes. Unpaved remnants of the old roads still approach the point, but landslides and a stone wall block motorists from the nature preserve at the point.

There are many others in Hawaii, and also Alaska.

KY looks like it has some that end at marinas on Kentucky Lake

Not sure if it would count or not... KY 39 dead ends (twice) on either side of the Kentucky River in Jessamine/Garrard Counties.

KY 595 dead ends at Poosey Ridge in Madison County.

No examples that I can think of in either Vermont or New Hampshire.

[Flint1979]

Not sure if mentioned yet, but US-41 and M-26 dead-end at Copper Harbor, and US-45 dead-ends in Ontonagon (though if it were me, I would route US-45 up to Houghton on M-26).

M-26 ends at US-41 and US-41 continues on to the dead end without M-26.

Well there is a dead end sign and where US-41 ends there is a Road Ends sign with a red diamond on it so I'm assuming that's where the road dead ends. After that it's basically just an ATV trail with lots of potholes and ruts.

Technically not state routes (since Spain is not dividied into states but communities), but here's a list of regional roads of Aragon that dead-end:
- A-135
- A-139 (the only true dead end, all others end at parking lots)
- A-2520 (technically, an unpaved road continues beyond the parking lot)
- A-2606
- A-2617

This means from this roundabout one is going to hit a dead end no matter which direction chooses (unless of course one turns back).

During the time France closed their borders due to that virus, A-136 and A-138 also technically dead-ended. N-330a, the old Somport pass road, at least has a turnoff back into Spain right at the border. The only border crossing open to trucks was the Somport tunnel.

NY 25 and NY 27 here on Long Island.  The former is a proper dead end where you run out of land at Orient Point.  The latter has a circle at the end where the eastbound lane loops around and becomes the westbound lane at Montauk Point State Park.  Also, MD 272 has a dead end in Elk Neck State Park.

My bad, I must have misinterpreted the question. I was thinking about state-level routes that do not end at other state-level routes (i.e. US-45 ending at a neighborhood street in Ontonagon).

The Dead End sign is just after the campground entrance to Fort Wilkins State Park and there is a 55 mph speed limit sign there too. The Road Ends sign with the red diamond is at the entrance to Mandon Road where it turns to dirt.

FL 320 in Levy County is 6 miles long and ends at the entrance to Manatee Springs State Park.

[Flint1979]

US-45 doesn't exactly dead end. The street that US-45 ends on dead ends but US-45 ends about 1 or 2 blocks before that so you could call it a dead end I guess. I don't know why it doesn't end at it's intersection with M-38 and M-64.

FL 320 in Levy County is 6 miles long and ends at the entrance to Manatee Springs State Park.

But the road keeps going, doesn't it?

Florida interestingly doesn't have as many examples as it might seem on the surface.  A lot of Old State Roads which did once have no outlet were turned back over to the counties.  FL 679 would be an example of one that still ends but the continuing road has no outlet (Mullet Key).

The marker in the cul-de-sac at US-41's northern terminus.  Mandan Road is to the left in the background, but as Flint1979 noted it's really not passable for most vehicles.

Either way Mandan Road doesn't have an outlet.

Colorado Highway 150 dead ends at a campground at the Sand Dunes National Park. There is a 4WD road that diverges just before the terminus that goes up over Medano Pass.

An honorable mention goes to CO 170 where State maintenance ends at Eldorado Springs but the road continues outside of the town as dirt and dead-ends about 3 miles later in Eldorado Canyon State Park.

Interestingly CO 150 used to be a through highway via Mosca Pass.  The road still exists but has eroded down to a trail:
