Routes that almost touch

[hotdogPi]

They must almost touch, but not touch at any point. (Crossing over with or without an interchange still counts as touching.)

NH 88 and NH 84: 300 feet
VT 23 and VT 30: 260 feet
MA 31 and CT 197: 220 feet
I-89 and VT 117: 180 feet
MA 125 and NH 121A: 100 feet
NH 101 and NH 121: 63 feet (shoulder to shoulder)


If you have some examples, make sure they are 500 feet or less.

[Mapmikey]

I-81 and VA 372 - 174 ft
I-81 and VA 336 - 74 ft
VA 86 and VA 398 - 284 ft
I-81 and VA 305 - 123 ft
VA 319 and VA 357 - 79 ft
US 50 and VA 338 - 234 ft
US 15-17-29 and VA 355 - 102 ft
I-95 and VA 353 - 57 ft
I-64 and VA 388 - 195 ft
I-64 and VA 39 - 173 ft
VA 209 and VA 267 - 83 ft

alas, I-88 and I-355 do intersect at the ends of their parallel section, because otherwise this would be the quintessential example.

so, then, I-276 and I-95.  they cross over, yes, but they do not touch, in the sense that a vehicle can reasonably proceed from one to the other.  so, what's the vertical separation between the two?  that might be our answer.

Are there any routes that cross freeways without any access, but still officially exist to the dead end on each side?

you mean where the overpass is not part of the state highway system but the approaching roads both are?

[hotdogPi]

Just found a really close one (37 feet if using the dashed line): I-690 and NY 5.

No, where there's no overpass. Something like http://maps.google.com/maps?ll=41.347989,-84.245589&spn=0.006532,0.014173&gl=us&t=k&z=17 but with a numbered route.

[agentsteel53]

ah okay, we had a different interpretation of the word "cross".

I'll bet there's some VA secondary here or there that stops at a freeway, and then has a counterpart on the other side with a different number.

What is the distance between NJ 23 and I-84?  If it is less than 500 feet then it would qualify.

Just barely missed, 600 feet.

[roadman65]

Then NJ Secondary CR 521 has to, because the NJ State Line is very close to the I-84 bridge.

170 feet.

[roadman65]

I knew it had to be because once you travel EB across the DE River on I-84, you can look down and almost touch the NJ State Line below.  There is (or at least was in 1998) that was just south of I-84 saying either "Entering Sussex County" or "NJ State Line" at that particular crossing.

Maryland almost certainly has this in its primary system but I don't know if any are actually posted.

The closest I can think of is in Virginia is SR 621 east of Manassas but neither side truly dead ends at the freeway.

If the criteria is just continuing a designation across a freeway with no overpass and doesn't have to involve dead ends, Texas would certainly have some...

NY 49 west and the Thruway: 20 feet, shoulder to shoulder.  Eastbound crosses over.

CA 83 on Euclid Ave terminates at the CA 210 freeway overpass in Upland, but doesn't have an interchange with it.

I think the maintained SR 83 ends at 19th Street (old SR 30).

[Alps]

NJ 161 and NJ 3
NH 26 and VT 102
I-280 and US 46
GA 13 and GA 400
MD 835A and US 50/301 (and similar situations elsewhere in the state)

U.S. 1 and U.S. 29 come within a block of each other without "touching" in the District of Columbia - U.S. 29 at 7th Street, N.W. and Rhode Island Avenue and U.S. 1 at 6th Street and Rhode Island Avenue, but the distance (according to Google Maps measuring tool) is about 570 feet.

[getemngo]

All the stupid things that happen in downtown Detroit. Looks like 3 blocks is the minimum.

In Nebraska, the best I can come up with, at least offhand, is NE 31 and the official unofficial route of NE 66 through Louisville (if that makes any sense), the separation of which is the NE 50 bridge over the Platte River, although strictly by looking at a map, US 30 and I-80 way out west appear to be on right of ways which are next to each other, but they never intersect in Nebraska.

In Minnesota, MN 56 and US 52 are very close together in Hampton, right as MN 56 ends.

Virginia Secondary Route 650 in Fairfax County terminates at Route 236 about 157 feet west of the western terminus of Route 244: https://www.google.com/maps/dir/38.8305135,-77.1961758/38.8306054,-77.1967123/@38.8323522,-77.1939979,17z/data=!4m3!4m2!1m0!1m0

(If you look at the Street View of that intersection, you can find some ugly Virginia primary shields on the south side and some weird street signs that abbreviate "Turnpike" as "Trnpk," which every time I see it makes me wonder why bother abbreviating an 8-letter word at all just to save three letters.)

OLD SR 50 and FL 50 near the Orange/ Lake County Line between Winter Garden and Clermont, FL.

[Brandon]

Illinois:

IL-171 and IL-43.  They are about three blocks apart in Summit when IL-171 turns off Archer onto First.
IL-70 and IL-2.  IL-70 ends about two blocks west of IL-2 at Bus US-20 in Rockford.
IL-115 and IL-50.  IL-115 ends at US-45/52 three blocks west of parallel IL-50 in Kankakee.
IL-113 and US-45/52.  IL-113 ends at the west end of the IL-17 Kankakee River Bridge while US-45/52 is at the east end of the bridge in Kankakee.
IL-91 and IL-6.  IL-91 ends about a half block west of the IL-6 interchange on US-150 in Peoria.

Honorary mentions as these do cross at one time, but come really close together at a different time:

US-30 and US-52.  The cross in Amboy, but come within four blocks of each other in Joliet.
IL-111 and I-255 (IL-255).  IL-111 crosses IL-255 twice in Wood River and Bethalto, but ends just before I-255 in Centreville, with no interchange, I might add.

[roadman65]

NY 100 and the Taconic Parkway in Westchester County, NY actually brush each other.
