Numbered routes that should be merged?

[TheGrassGuy]

I'll go first: CO-16 and CO-21 in Colorado Springs.

Don't we have at least 15 of this thread topic in fictional already?

Found one for interstates https://www.aaroads.com/forum/index.php?topic=25256.0

I actually took this into consideration. Looked up "CO-21", but there were no matching threads.

Most Colorado posters here use "˜SH-XX' for their state routes. If you're going to use a route number to search for a combining routes thread, use I-44 or I-64, as they're the most commonly suggested ones for some reason.

- MS 25 and (West) MS 18
- US 49 and US 63 (lets pretend 63 still ends in Memphis and 49 still ends in Clarksdale)
- US 212 and US 8
- MS 69 and MS 12 (north of columbus, 12 is overlapped with US 82 until that point)
- AL 95 and AL 165
- US 280 and US 78 West of Birmingham
- US 72 and US 74
- AZ 64 and 264
- US 89 and AZ 87 (it could dog leg over there somehow)
- US 60 and CA 62

US 641, KY 91, Cave-in-Rock Ferry, IL 1

[SkyPesos]

Here's one (two?) I mentioned a lot on this forum:

US 22 and US 42 in KY
US 25 and US 42 in OH

In regards to I-44 and I-64, while they do connect in St. Louis, I feel the overall trajectories of each highway are different enough to merit (retain) separate numbering.

That's my general concieus too. I-44 is a diagonal SW-NE route, while I-64 is mostly straight, with a NW-SE (opposite of I-44's trajectory) between Richmond and the Hampton Roads. That's why I didn't combine those two routes together in my fictional interstates thread in my sig.

Meanwhile for I-29 and I-49 at the other side of the state, I combined them as a single I-45.

Why didn't you put this one in Fictional too, then?

[Roadgeekteen]

How many times have we talked about this?

[TheHighwayMan3561]

- US 212 and US 8

This may have been sensible when they were at their full extents, but as they presently constitute it doesn't make sense to do this anymore.

One I've seen from Steve Riner is MN 15 and MN 371.

Mine:
MN 72 and MN 46
MN 58 and MN 57

[hotdogPi]

US 72 and US 76

[JoePCool14]

I-5 and I-95

[kphoger]

69E, 69C, and 69W

[SkyPesos]

I-5 and I-95

I-10 and I-90

[Roadgeekteen]

I-5 and I-95

I-10 and I-90

US 1 and US 101

[hotdogPi]

MA 40 and MA 133
MA 60 and MA 117
I-180 (WY) and /dev/null

Is there a reasonable way connect MA 114 and NH 114? Maybe via current NH 128?

[JoePCool14]

I-180 (WY) and /dev/null I-180 (IL)

[CNGL-Leudimin]

US 32 and US 38. Oh, wait, they did. As US 6 .

[KeithE4Phx]

- US 89 and AZ 87 (it could dog leg over there somehow)

Coconino County Hwy 3 (formerly Forest Hwy 3), better known as Lake Mary Rd., connects I-17 in Flagstaff to AZ 87.  It would require new ramps to I-40 to link with US 89 at Country Club Dr (US 180) as well as having ADOT take over maintenance on CH 3.

[hbelkins]

By "merged," do you mean continuing a route as one number as opposed to two separate numbers, or do you mean two numbers running concurrently that should only be one number (a useless concurrency, like the southern end of US 319 that is totally concurrent with US 98)?

[KCRoadFan]

US 33 and VA 33. Seriously, why does the latter even exist? If I were VDOT, I would just make the whole thing US 33.

Same thing with US 15 and NY 15, US 3 and MA 3 - you get the idea. Just have the US route take over the whole road.

[KCRoadFan]

US 18 and M-46.

The idea: have US 18 cross Lake Michigan via ferry like US 10 already does. From its current eastern terminus on Michigan Street in Milwaukee, US 18 would be extended down I-794/Lake Parkway to the Port of Milwaukee exit; from there, it would follow the car ferry across the lake to Muskegon. Once it comes ashore there, US 18 would then follow Lakeshore Drive, Laketon Avenue, Seaway Drive, Muskegon Avenue, and Apple Avenue to the current western terminus of M-46; east of there, US 18 would replace M-46 across the state, ending in Port Sanilac at M-25 along the shore of Lake Huron. (Of course, US 18 could also be extended south from there to Port Huron and have its eastern terminus at the same spot as I-69 and I-94, taking over the southernmost segment of M-25 in the process.)

Michigan users, what do you think of this idea?
