Dirt Roads

Missed a few here in North Carolina that meets the OP criteria:
  • I-440 Beltline "westbound" -to- Western Boulevard eastbound (5,500 AADT) and Western Boulevard westbound -to-the Beltline eastbound (6,900 AADT)
  • I-540 eastbound -to- US-70 Glenwood Avenue westbound (5,000 AADT) and US-70 Glenwood Avenue eastbound -to- I-540 "westbound" (4,400 AADT)
  • I-540 "eastbound" -to- I-87/US-64/US-264 westbound (13,000 AADT) and I-87/US-64/US-264 eastbound -to- I-540 "westbound" (15,500 AADT)
  • I-240 eastbound (east side)*** -to- I-40 westbound (11,500 AADT) and I-40 eastbound -to- I-240 westbound (9,800 AADT)

And there are some of the "Other ones" here in North Carolina:
  • I-485 outer loop (south side) -to- I-77 northbound (8,800 AADT) and I-77 southbound -to- I-485 inner loop (8,100 ADT)
  • I-485 inner loop (south side) -to- I-77 northbound (21,000 AADT) and I-77 southbound -to- I-485 inner loop (23,000 ADT)
  • I-485 outer loop (west side) -to- I-85 "northbound" (5,100 AADT) and I-85 "southbound" -to- I-485 inner loop (5,900 AADT)
  • I-485 outer loop (north side) -to- I-77 southbound (13,000 AAADT) and I-77 northbound -to- I-485 inner loop (13,500 AADT)
  • I-485 inner loop (east side) -to- US-74 Independence Boulevard "westbound" (5,600 AADT) and US-74 "eastbound" -to- I-495 outer loop (6,200 AADT)
  • Lopsided!  I-485 inner loop (south side) -to- US-521 Johnston Road (5,400 AADT), but US-521 southbound -to- I-485 outer loop (only 2,800 AADT)
  • I-440 Beltline westbound -to- US-1/US-401 Capital Boulevard southbound (4,600 AADT) and Capital Boulevard -to- I-440 Beltline "eastbound" (5,200 AADT)
  • I-440 Beltline "eastbound" -to- New Bern Avenue westbound (6,500 AADT)*
  • I-540 "westbound" (west side) -to- I-40 eastbound (7,500 AADT) and I-40 westbound -to- I-540 "eastbound" (6,800 AADT)
  • Not fair!  This one goes to the airport: I-540 "westbound" -to- Aviation Parkway southbound (8,900 AADT) and Aviation Parkway northbound -to- I-540 "eastbound" (9,300 AADT)
  • No data yet on I-885 northbound -to- I-85 "southbound" and vice versa**
  • I-73 southbound/I-840 "westbound" -to- I-40 eastbound (8,100 AADT) and I-40 westbound -to- I-73 northbound/I-840 "eastbound" (7,600 AADT)

* The onramp from New Bern Avenue is a left turn across inbound traffic (and picks up traffic from Business US-64/Business US-264).
** Because these movements were (and still ire) Bypass US-70 before the completion of I-885, it probably shouldn't meet the OP criteria.
*** No need to point this one out because there *still* is no connection from I-240 westbound/I-26 "westbound" -to- I-40 eastbound on the west side of Asheville.

CT has:

I-84: Full set of wrong-way connections with CT 72; Reciprocal West-East connections with CT 2; Reciprocal West to East connections with I-384 and East to West with I-291 (latter 2 in the same interchange complex in Manchester

I-91: Reciprocal South to North connections with I-95 and CT 40; Full set of wrong-way connections with CT 9; Reciprocal South-North connections with CT 3; Reciprocal North-South connections with CT 15 in Hartford

I-95: Several other reciprocal South to North connections, including CT 8/25, SR 796, and CT 9 (but no direct ones at I-395)

CT 15: North to US 7 South; full set of wrong-way connections with CT 25, South to CT 8 North, reciprocal North-South connections with SR 796


Interstates I've clinched: 97, 290 (MA), 291 (CT), 291 (MA), 293, 295 (DE-NJ-PA), 295 (RI-MA), 384, 391, 395 (CT-MA), 395 (MD), 495 (DE), 610 (LA), 684, 691, 695 (MD), 695 (NY), 795 (MD)

Quote from: DTComposer on December 30, 2025, 12:09:50 AMI would guess the 4-level interchange in Los Angeles would be a contender, since both US-101 and CA-110 are signed north/south.

Without the AADT numbers on hand, I'd wager NB 101 to SB 110, and NB 110 to SB 101

I'd also like to add SB 405 to NB 101, which is backed up even on weekends.
