Routes that Meet But Don't Cross

[webny99]

I did several searches and, surprisingly, couldn't seem to turn up this topic.

What are some routes that meet at an intersection, but don't cross each other? Essentially, this happens when both routes make a turn at the intersection, so if you continue straight on any approach, you will switch to the other route. Yet the routes themselves, if you follow them, don't technically cross each other.

I remembered NY 77 and NY 63 as being a good example, but, unfortunately, I forgot that they have a short multiplex. Are there any other examples of routes that "kiss" at an intersection, but don't cross?

Do you mean like a "bump" –such as I-76 and I-80 near Akron, OH?

Precisely, yes. If that was a standard interchange, and not a double-trumpet, the two roads wouldn't share any pavement.
And I don't know how I forgot that obvious example.

[briantroutman]

Just a guess, but I'd imagine that this is not unheard-of in the Midwest and Plains states where rural routes often follow the PLSS grid and a diagonal or curved route is often approximated by a stair-step alignment of 90° elbows. So if a north-to-east route encountered a south-to-west route at a four-way intersection, you'd get that kind of a bump.

Like I-80 and I-74 in Colona, Illinois?

I know we had this discussion once before because I included an example which the OP was unusual even for the topic at hand:  https://goo.gl/maps/3H7utQPzVrn .

NJ 47 (Delsea Drive) & CR 663 (Tanyard Rd):  You can see in the picture the roads curve away from each other, and a GSV view will show there's a fence there.  A historic aerials view shows that it appears around 1970 construction of a connector road between the two was going on, when they blocked the two roads from each other.

CA 1 meets US 101 several times and even is concurrent in various places.  That being said CA 1 never actually crossed over US 101 and always remain south or west of it.

CA 1 meets US 101 several times and even is concurrent in various places.  That being said CA 1 never actually crossed over US 101 and always remain south or west of it.

But in all of the examples I can think of–such as in Marin County where I lived–there's a 1/101 concurrency (e.g. from the Presidio to Marin City) and the two routes then diverge. The OP isn't looking for that. He wants examples where the two routes come together at a four-way intersection; one forms an L and the other forms a 7. The L and 7 touch at one point, but there is no concurrency, and they do not cross each other.

CT-140 and CT-286 "kiss" in the center of Ellington. Maple Street runs about 20 feet between the two.

This is almost an example, but unfortunately NJ 34 and NJ 70 end here, and only NJ 35 does the 90-degree turn thing.

Though US 1 and ME 9 cross, join, and do all sorts of wacky things in Maine, they do bounce off each other in Saco, or close to it at least.

Not many California examples.

Route 247 and Route 18 ALMOST do this, but miss by literally one block:

If I-238 and State Route 238 are considered as one route, then I-580 has that sort of dynamic with it in Castro Valley (though whether that is still true with 238 surface street relinquishments in Hayward northward is up for debate)

I thought of the 18/247 but then I saw what you just described regarding them not touching:

Now what interests me is that little tiny connector road maintained as part of Route 18 or 247 by Caltrans or is it local?  I'll dig on the postmile tool when I get home to see. 

[US 89]

US 89 and SR 186 bump at State Street and 400 South in Salt Lake City, UT. Interestingly, before 2007 these routes actually crossed here, but they still bumped at North Temple and 300 West.

SR 115 and SR 147 bump in Benjamin UT, at the intersection of 3200 West and 7300 South.

US 34 and US 36 bump in Estes Park CO, at the intersection of Wonderview Ave/Big Thompson Ave/Elkhorn Ave/St Vrain Ave.

[hbelkins]

US 150 and US 136 in Danville, Ill.

US 45 and IL 1 in Norris City, Ill.

Like I-80 and I-74 in Colona, Illinois?

If what is marked as I-280 on Google Maps is in fact a multiplex with I-74, then yes, that's a great (and again a fairly high profile) example.

[Super Mateo]

US 6 bumps IL 7 in Orland Park, IL (stoplight).  Both routes meet again at a stoplight at IL 7's southern terminus.

US 45 bumps IL 83 in Mundelein, IL (stoplight).  Further south, those two routes cross at an interchange in Palos Hills.

If what is marked as I-280 on Google Maps is in fact a multiplex with I-74, then yes, that's a great (and again a fairly high profile) example.

It is both I-74 and I-280 concurrent going west from that interchange.

[hotdogPi]

While not quite what the OP wanted (no access between the roads where I'm talking about), I-690 and NY 5 is an interesting example. They are grade-separated, but there is no access between them where they "meet", that is, if they do meet. Whether they meet or not depends on how large you define the intersection to be. If it's everything between the crosswalks, a 10 foot by 5 foot triangle (this is less than the area of a single car) of NY 5 is under I-690. However, since it's a left turn, no car staying on NY 5 would ever be directly under I-690.

I-91 and CT 15 in Meriden, CT   The northbound lanes of CT 15 cross over I-91 twice so that the route straddles I-91, but the southbound lanes of route 15 bump but never cross.

US 6 and CT 66 in Columbia, CT.  US 6 turns left onto the Willimantic bypass straight across from where CT 66 intersects from the west.  CT 66 then turns right onto the local road that US 6 once occupied.

MO 45 and MO 92 near Weston Bend State Park come very close together but never touch.

The example being discussed in the Indiana thread, IN 2 and US 20 west of South Bend.

Oh, that fucked up one.  Why in the name of anything and everything holy does InDOT make US-20 take the 2-lane POS called a road instead of the nice 4-lane divided highway!?!

[GaryV]

What about routes that join for a while, then split off again?  Like M-28 and M-94 in the UP SE of Munising.  The parts that are separate from each other are in the same relative orientation, not crossing.

[briantroutman]

It appears the OP isn't interested in any examples where routes overlap:

I remembered NY 77 and NY 63 as being a good example, but, unfortunately, I forgot that they have a short multiplex.

[cwf1701]

I-96 and M-5. Eastbound i-96 doesn't cross M-5 while westbound i-96 does cross M-5 twice in the interchange complex.
