Multiplexes on freeways with no exits in between

[kj3400]

I was thinking about how I-83 in Baltimore multiplexes with I-695 for about a mile with no exits in between both ends of the multiplex. It hops on and right back off again. Are there any other such multiplexes out there?

US 41 is Multiplexed with I-75 in GA between Hahira and Valdosta, and there are no exits in between the two exits where US 41 joins/leaves I-75.

NY 7 is multiplexed with I-87 from exit 6 to exit 7 just north of Albany.

One in SE Mich:  M-14 multiplexes with US-23 on the north side of Ann Arbor with no exit between the interchanges.

MA 140 hops onto MA 2 (a freeway) for one exit.

But why does MA 140 do this? It could just use MA 2A and W Main St. (I want an answer for this.)

My first thought was TX 108 along I-20 between consecutive exits.  There's also TX 17 along I-10 and TX 70 along I-40.

US 10 multiplexes with I-43 near Manitowoc WI from exits 152 to 154. and WIS 42 on I-43 from exits 149 to 152.

US 1 does in Pawtucket, RI.  It hops right on and then off just to cross a river.

US 1 does it again to cross the Connecticut River on I-95 near Old Saybrook, CT.

US 9 does it in New Gretna, NJ with the Garden State Parkway.

If NJDOT would only ask FHWA to reroute US 9 across the Great Egg Harbor Bay Bridge being the Beeslys Point Bridge will never be rebuilt, then another instance would be.

I-35E/I-94 St. Paul, MN
I-35E/I-694 MN
I-90/MN 43
I-94/US 10/(hidden US 12)/US 61 St. Paul, MN (the US 61 part)
I-94/MN 95
US 14/MN 56 (technically, if you consider that the 14/56 North intersection is where US 14 ends as a freeway)

I-59/MS 43 Picayune, MS

If NJDOT would only ask FHWA to reroute US 9 across the Great Egg Harbor Bay Bridge being the Beeslys Point Bridge will never be rebuilt, then another instance would be.

That doesn't specifically require FHWA's permission...just AASHTO.

(former) I-540 & I-40 Alma-Van Buren AR

[roadman65]

US 19 does in GA on the north side of the I-285 loop.

[jp the roadgeek]

US 1 does it again to cross the Connecticut River on I-95 near Old Saybrook, CT.

So does US 44 on I-84 to cross the same river, and US 1 with I-95 in New London again to cross the Thames.

I-587 and NY 28. Owned.

OH 49 does so with I-70 with a pair of partial interchanges.  US 224 sort-of does so with US 30 but US 30 isn't a full freeway (despite the 65 mph limit)--there are a few intersections with local roads in between--but the entry and departure of 224 are at consecutive interchanges signed with BGS.

 OH 16 and OH 37 in Granville

[hbelkins]

I-75 and US 25/421, exits 97 and 99 in Kentucky. This is the Clays Ferry Bridge crossing the Kentucky River.

The original southbound span was built for 25/421 to replace the old one-lane metal truss bridge down at the valley floor. The northbound span was added later, then the center span in the 1990s when the road was widened to three lanes in each direction.

I think KY 61 may use part of I-65 in Louisville but I'm not positive, and I also don't know that if it does, it joins and departs at successive exits.

Also, I-64 and Truck KY 627 between exits 94 and 96 near Winchester.

I 75 and US 23 wrong way south of Toledo

US 78 in Mississippi is fond of these. MS 9 does it near Sherman, and MS 25 does it (at least for the next 15 years or so, until the proposed Amory bypass is extended north) near Fulton. And MS 4 and MS 7 are scheduled to multiplex with US 78 between exits 26 and 30 near Holly Springs eventually; most of the signage is in place, but for some reason it's never been unveiled.

I-74 and I-280 in the Quad Cities. At 10 9 miles, I would guess that it's probably one of the longest that would fit this thread.

[Brandon]

US-20 with I-39 and US-51 in Rockford, IL.  Between where I-39/US-51 enters the freeway and then US-20 exits 3 miles later.

US-20 with I-290 in Elmhurst, IL.  Between Exits 12 and 13 for just a mile.  Truck IL-64 also shares this pavement with US-20 for the same distance along I-290.

[bassoon1986]

I-49 & LA 8 - Boyce, LA (3.5 miles)
I-20 & US 371 - Minden, LA (2.6 miles)
US 167 expressway and US 71 - Tioga, LA (2.9 miles)
I-310 & LA 3127 - Boutte, LA (1.6 miles)

I-20 & US 80 - Waskom, TX (4.4 miles)
I-20 EB & US 287 - Fort Worth, TX (1.3 miles)

California examples:

- US 101 and Route 84 in Redwood City, between Marsh Road (Exit 406) and Woodside Road (Exit 408)

- Route 84 and I-880 in Fremont, from Thornton Avenue (Exit 19) to Exit 21

- Route 12 and Route 99 in Lodi, from Kettleman Lane (Exit 264) to Victor Road (Exit 266)

- Route 120 and Route 99 in Manteca, from Exit 241 to Exit 242

- Route 152 and US 101 in Gilroy, from Exit 356 to Exit 357

- Route 33 and I-5 north of Coalinga, from Exit 337 to Exit 349

- Route 74 and I-215 in Perris, from Exit 15 to Exit 17

Not sure if 54 along Route 125 in Spring Valley between Exit 11A and Exit 13 counts anymore.

In Mansfield, MA; MA 140 piggy-backs along I-495 (between Exits 11 & 12).

[NWI_Irish96]

In Indiana:

IN 331 multiplexes with US 20 for one exit.

Can't think of any other examples right now.

[hotdogPi]

In Mansfield, MA; MA 140 piggy-backs along I-495 (between Exits 11 & 12).

MA 140 hops onto MA 2 (a freeway) for one exit.

So it does it twice, in completely different locations... 140 is kind of a strange route.
