Same freeway, same route numbers for different intersecting routes

[The High Plains Traveler]

The central section of I-35 meets both I-35Es and I-35Ws. I consider I-35 to be split into three sections, with gaps on Hillsboro-Denton TX and Burnsville-Lino Lakes MN sections (Where it splits onto I-35E and I-35W).

For purposes of route continuity, though, both Texas and Minnesota sign their I-35E segments with mileposts and exit numbers corresponding to I-35. I don't remember what kind of signage Texas has at the end of the branched segments, but Minnesota signs each branch with something like END [I-35E] BEGIN [I-35] 1 MILE.

There are quite a few cases in Southern Illinois/Indiana, but there's one that especially sticks out in my mind.

Only 15 miles separate Indiana 64 and Interstate 64 between Princeton and Evansville on U.S. 41. What's most interesting about this one is that there is a distance sign on Southbound U.S. 41 that states only those two routes. It reads, "Indiana 64 - 10 [miles], Interstate 64 - 25 [miles]," so as to alert the drivers which one is which...or to confound them further.

Also of note: I-64 has Indiana 65 and Interstate 65 about 110 miles apart. I-64 also has I-57 in Illinois and Indiana 57 near (again) Evansville. However, with Interstate 69 in bloom, I do not know if Indiana 57 is still relevant.

This has to be the winner. In Texas, US 75, which is a freeway, intesect both FM 121 and SH 121, within 10 miles. There is a unique sign on SB US 75 that somehow tells motorists not to confuse FM 121 with SH 121.

Even closer than that, Indiana 69 is only about 20 miles to the west of what will be Interstate 69 (current I-164.) As for Interstate 64, it does/will cross "69" at Exits 4 and 29.

Does.  The road to the north is already I-69.

Interstate 64 intersects with Indiana 64 in Floyd County.
Interstate 65 intersects with Indiana 60 in Clark County and just 9 miles to the south crosses over US 60 in Louisville, though there is no direct exit for US 60.
Interstate 65 intersects with Indiana 62 in Clark County and 50 miles to the south intersects US 62 in Elizabethtown, KY.

Heading south from downtown Atlanta on I-75, I-85 is exit 242 and GA 85 is exit 237A. It's confusing enough now, but it was worse before I-185 was built and GA 85 was the main route from Atlanta to Columbus.

OT, but I usually can't post here. It's torture wanting to contribute and being unable to. HELP!!!

I-12 in Louisiana - intersects LA 59 at Exit 65, then I-59 in the Exit 85 complex. Eastbound travelers on I-12 will actually see TO I-59 signage on the Interstate indicating they should remain on it to reach I-59.

Oregon (the one and only example), I-84 intersects I-82 at exit 179, and Oregon 82 at exit 261 - 80 miles apart

Technically, US-30 and I-84 intertwine since US-30 practically is Business I-84, so that would count. 

Uh, WA-20, US-20, CA-20 on I-5.

I-35W intersects US 67 (Alvarado, TX) and FM 67 (near Covington, TX) at a 13 mile interval. 

[Occidental Tourist]

Confusing no one except drunks, along I-10, there's US 95 in Blythe, CA, and Az 95 17 miles to the east in Quartzsite.

What about US 41 and Pasco County, FL 41 intersecting I-75 in Florida?

[briantroutman]

Not within the same state (and not a freeway) but a similar idea...

Between Harrisburg and Selinsgrove, US 11/15 intersects with PA 17 in Liverpool. Last I drove through the area, PennDOT had a small panel above the PA 17 trailblazer: "NY ROUTE 17" with an up arrow. Yes, US 15 does intersect NY 17–over 130 miles north of there.

Apparently, PennDOT anticipates someone saying "Hey, we got to the turn-off over two hours earlier than I expected."
