Interchanges with ramps in two states

[geocachingpirate]

I found it interesting zooming into Danville, VA seeing US 58 so close to the border of NC and then seeing the interchange with Bus 29 having ramps going in and out of NC right back into VA. 
What's some other occurrences of this?

I-95 south, Exit 60 in Massachusetts, actually begins in New Hampshire.

US 3 near the Pheasant Lane Mall has the MA/NH border going through one ramp.

The I-95/495/DE 92 interchange in Claymont, DE has definitely one (southbound split) ramp and another (northbound merge) ramp that encroaches into PA.

I-84 & Saw Mill Rd. (Exit 1 in CT) encroaches into NY.

The Pointe Fortune interchange on both ON-417 and A-40 straddles the ON/QC border.  The ramps are located primarily on the Quebec site, with the grade separation located entirely on the Ontario side.

I-55 Exit 291 in MS/TN has its northbound entrance and southbound exit ramps begin in Tennessee.

I-86 (east)/NY 17 also dips into Pennsylvania near exit 60, but that entire interchange appears to be within Pennsylvania. The next interchange east, Exit 61, has its eastbound exit and entrance ramps begin/end in New York but terminate at PA 199. Across the state line is NY 34, which is served by the westbound exit and entrance ramps, entirely in New York.

I-55/69 exit 291 in Mississippi's northern ramps extend into Tennessee.

AR/TX Loop 151 at State Line Road in Texarkana has its eastern ramps in Arkansas and its western ones in Texas. But none of the ramps themselves cross the state line.

Similarly I-30 at State Line Road is an odd case because of the frontage roads and a ramp-reversal setup that was recently put in place. I'm not sure if it counts or not.

-I-86/NY 17 Exit 59A has part of its EB ramps in Pennsylvania, even though the mainline is about 150 feet short of the border

-Hutchison River Parkway / Merritt Parkway / CT 15 Exit 30/27 is split between NY and CT

-I-70 Exit 156 at the IN/OH line has one WB ramp that begins and ends in OH, but has the majority of its length in IN

-I-81 Exit 1 at the PA/MD line intersects Mason Dixon Road, with parclo ramps in both states

-I-95's South of the Border interchange is mostly in NC, but has ramps extending to SC

A near miss is I-287/NJ 17, which has a turnaround ramp less than 150 feet from the NY/NJ border

Exit 0 on the Indiana Toll Road ans Chicago Skyway (I-90) at the Illinois/Indiana state line.  Coincidentally, it's Exit 0 for both as the Skyway is mileposted backwards.

Interestingly enough, on northbound I-95, the ramp for Exit 1 seems to be entirely in South Carolina. I don't think you actually cross into NC until you reach the stop sign at the bottom. It's weird that NC Exit 1 starts in South Carolina. Are there other instances of this?

PA exit 1 on I-81 has 2 ramps entirely in MD. Judging by sign locations on nearby US 11, the state line is at the edge of PA 163's ROW, or at the stop sign at the end of the SB exit ramp. Right next to where the ramp departs from I-81 is a MD mile marker.

The Pointe Fortune interchange on both ON-417 and A-40 straddles the ON/QC border.  The ramps are located primarily on the Quebec site, with the grade separation located entirely on the Ontario side.

If you consider it a single large interchange, the RIRO ramps between the new northbound TCH/A-85 roadway and Ave. de la Madawaska (the old TCH) are in Quebec, while the RIRO ramps between the realigned southbound TCH/NB 2 and Madawaska Ave. are in New Brunswick.  The grade separation is entirely on the New Brunswick side.

Exit 75B on I-435, for State Line Road, has ramps in both Kansas and Missouri.

I-35's exit for US 69 on the south side of Lamoni, Iowa, which is Exit 114 in Missouri, is right on the Missouri-Iowa border.

I guess this counts. The interchange of US-95 and US-195 is right on the WA-ID border: https://www.google.com/maps/@46.4755958,-117.0326136,15z

Why is it so redundant? It seems like waste of pavement, especially with the channelized right turn and left turn lane that dualizes the movement make by a ramp 1/4 mile south?

Without looking further into it, maybe what Google labels BUS-195 was the old intersection, and they built the current grade separated interchange later, and left the old one as is (mostly to provide the other 2 less important connections).

In Indiana, ramps for the I-70/US-40 interchange near Richmond lop over into Ohio: https://www.google.com/maps/@39.8335273,-84.815819,18z?hl=en

The ramps from I-49 to and from US 59-71 north of Texarkana enter Texas for a short stretch.

N1 J20 has half a ramp, and a section of the mainline, in Northern Ireland, with the rest in the Republic of Ireland

There is an interchange at the Arkansas/Oklahoma state line on I-40. The ramps from EB I-40 and to WB I-40 are in Oklahoma, while the ramps from WB I-40 and to EB I-40 are in Arkansas. The signs in Arkansas simply are for "Dora" while the signs in Oklahoma point to OK 64D and list the control cities of "Dora" and "Ft Smith". OK 64D runs north from US 64 just west of the Arkansas River and ends where the roadway curves into Arkansas in the middle of the interchange. OK 64D is a handy shortcut from I-40 to downtown Fort Smith.

I-29 exit 1 in ND is off by about 30 feet.

Exit 460 on I-25 in NM is partially in CO.

Both of those go nowhere interesting. (although at Exit 460, you can tell where the state line is by the pavement suddenly degrading/upgrading, depending on direction)

Exit 1 on I-84 in CT has some of the ramps partially in NY.

I find it a little easier to get off on 64 at Roland

I-84 & Saw Mill Rd. (Exit 1 in CT) encroaches into NY.
