Most US Routes at one intersection

[roadman65]

Other than the 465 Indy Beltway, places where many US routes  over the amount of four converge at one point.

McRae, GA has five different US routes intersect at one intersection. US 23/341 intersect US 280/319/441.

Downtown Lexington, Ky. (corner of Main & Broadway, and also Vine & Broadway) -- US 25, 27, 60, 68 and 421.

Downtown Cincinnati -- US 22, 27, 42, 52 and 127.

[dfilpus]

Cleveland - Public Square: US 6, 20, 42, 322, 422 (The last three terminate there).

[ET21]

US 12-20-45 LaGrange Road and US 34 Ogden Avenue in LaGrange, Illinois.
US 20, 52, 151, 61 in Dubuque, Iowa

Broadway at Rosa Parks in Nashville: looks to me like US 31, 41, 431, 70, 70S are all there.

Cleveland - Public Square: US 6, 20, 42, 322, 422 (The last three terminate there).

And if you go back at least 40 years, you could've added a 6th one -- US-21.

If we're looking at historical US routes, then I think the intersection of Michigan Ave with Jackson Drive/Adams St (one-way couplet) in the Chicago Loop could be a contender right around 1959-1960. At that time, my understanding is that Jackson Dr used to be US 34-66 (ending at Michigan Ave); Michigan Ave was US 14 and City US 12-20 coming from the north and US 54 and City US 12-20 coming from the south. This totals six routes: US 12City, 14, 20City, 34, 54, and 66.

Two other US routes were nearby. At that time, I believe ALT US 30 (former US 330) came close to this intersection but stayed south of there (turning west from Michigan Ave onto Roosevelt Rd). US 41 was at one time posted on Michigan Ave but was at some point (prior to 1959-1960) moved to the current Lake Shore Dr alignment.

Four is the most I've ever seen - the Madison beltline (12, 14, 18, 151).

In Los Angeles, wouldn't the Downtown Slot (between the Four-Level and San Bernardino Split) at one point (say, 1960) have connected six U.S. routes - 6, 60, 66, 70, 99, 101?

Columbia SC:

1, 21, 176, 321, 378 all intersect at one location.

Atlanta:

19, 29, 41, 78, 278 all occupy one location.

Asheville NC:

19, 23, 25, 70, 74 intersect in one spot.

Memphis used to have 61-63-64-70-79 on the same bridge.

Memphis used to have 61-63-64-70-79 on the same bridge.

did it have 63?  I know in 1963, the other four were present, along with I-40 and I-55.

I believe the Four-Level itself would count, but the downtown slot segment was missing 6 and 66, which went down the Harbor Freeway from the Four-Level.

(also, I think the section of I-5 between 110 and 101, which cut off the downtown slot, was in place by 1959.  at least, there are signs from 1959 on that segment.)

Officially at least, though it may not have been signed.

Asheville NC:

19, 23, 25, 70, 74 intersect in one spot.

Nope. 25 splits off the freeway north of the interchange where 19/23/70 meet I-240, and US 74 follows I-40 and I-26 and does not come near that intersection. US 74A is signed in Asheville, but again, 25 is missing from the equation.

Missing was my time machine to 1934 when they did...

I wonder what the longest duplex, triplex, quadraplex is.

I wonder what the longest duplex, triplex, quadraplex is.

historically speaking, this must be a contender:

US 60/70 (Globe, AZ to Banning, CA)
US 60/70/80/89 (Phoenix area)

for a modern example, I'll bet it's in North Carolina.  that state loves its US routes and its multiplexes.

here's a long-dead thread:

85-87 is pretty long, but not signed. 15-501 is 105 miles per the Goog.

[Mapmikey]

62-180 is about 263 miles...

Broadway at Rosa Parks in Nashville: looks to me like US 31, 41, 431, 70, 70S are all there.

Has the Rosa Parks name made it that far south?  I thought it ended at James Robertson Parkway.  Also I believe US 41A is signed through that intersection, and US 31A ends a few blocks south at 8th & Lafayette.

The thing is, though, I remember 8th & Broadway having restricted left turns, meaning at least that US 431 north would turn left on 9th and cut over on Church Street to James Robertson.

NJ manages to cram in four at US 1/9/46/9W, which isn't bad for a crowded Northeast state.
