How many are on the expressway system in your area?
Nearest one to me that I can think of is Exit 89 or so for Cabrillo Blvd. near Santa Barbara.
Here are the ones I can think off the top of my head...
A-20 E -> A-15 N (Montréal, Turcot interchange)
A-15 S -> A-720 (same interchange)
A-20 E -> A-73 N (Québec, Pierre-Laporte Bridge)
A-20 W -> Notre-Dame St. (Montréal, reversed section of A-20)
A-40 E -> A-15 S (Montréal, Metro Blvd to Décarie Expy)
A-730 W -> A-30 E (brand new 30/730 interchange in St-Constant)
QC-138 E -> A-20 W (Montréal after Mercier Bridge)
ON-417 W -> ON-416 S (Ottawa)
Exit 165 (I-5) - Seneca St. in Seattle, WA.
There's quite a few HOV left exits, but I don't feel up to listing them all.
Left exits are quite rare in the Bay Area, but they're used on the Bay Bridge, and on I-280 SB in its Northern junction with US-101. Also, there are a few HOV left exits.
It would be interesting to differentiate between left exits at system (freeway-to-freeway) and service (freeway to surface road) interchanges. In Wichita, there are no left exits at service interchanges, with the only movements that could plausibly be signed as left exits being at splits within system interchanges (I-135/I-235 "North Junction" and I-135/I-235 near the South Wichita interchange on the Kansas Turnpike).
Freeway splits are an ambiguous case because it is essentially an arbitrary decision to sign them as left exits and other conditions have to be met at an individual split before it can be considered to have the operational disadvantages ordinarily associated with left exits. For example, in a TOTSO situation at a standard wye interchange, the mainline route might take the right-hand branch of a split, which would require that the left-hand branch be treated as a left exit under some state exit numbering policies, but if traffic on the left-hand branch merged onto a new freeway from the right, the movement would not have any of the operational disadvantages of a left exit or left merge.
I-405 North in Portland is practically an entire left exit in itself! From I-5 North to I-405 North is a left exit, not to mention the very first exit (SW Naito Pkwy) is a left exit. Continuing on I-405 North, the next left is US 30 West, which is then followed by the US 30 East exit (technically just a movement to I-5 South). Other examples of a left exit in the Portland metro area:
I-5 South -> I-405 North
I-5 South -> Mt. Hood Freeway (the ghost ramp still exists)
Outside of the metro area, I-84 at Multnomah Falls (both directions)
A few of these in the LA County area:
I-5 North at Firestone Blvd
I-5 North -> I-710 North
I-710 South -> I-5 South
US 101 South -> I-10 East
Of course, there are the very numerous HOV left exits in SoCal...
Here's what we have in Rochester:
-I-490 east to NY 390 north
-I-490 west to I-390 south
-I-390 north to I-490 west
-NY 390 south to I-490 east
-I-490 east to Inner Loop clockwise
-Inner Loop clockwise to University Ave
-Left enterance from Inner Loop clockwise to I-490 east
-NY 590 south to I-490
-NY 590 north to NY 104 east (left enterance)
-NY 590 north to NY 104 west (left enterance)
-NY 104 west to NY 590 south
-I-390 south to I-590
St. Louis area
* I-44:
1) EB left exit to Lafayette Avenue (Exit 290B), was going to be a two lane ramp for MO 755
* I-55 (MO side)
1) NB left exit to WB I-44 and the Truman speedtrap
2) NB left exit to WB I-70 and Memorial Drive
3) SB left entrance from EB I-70 and Memorial Drive
The latter two will technically change to major splits/right exits off of I-44 after the new I-70 bridge opens, however this will create a left side entrance/exit situation with respect to I-44 at the southern I-55 interchange
* I-55 (IL side)
1) SB left exit to 3rd Street in East St. Louis
2) NB left entrance from the MLK Bridge
3) SB left exit to the MLK Bridge
4) SB left entrance from WB I-64/SB IL 3
5) NB left entrance loop from SB IL 3
6) SB left exit to EB I-64
* US 40/Avenue of the Saints corridor
1) WB/NB left exit to WB I-70 in Wentzville
2) EB/SB left exit to EB I-70 in Wentzville
3) WB left entrance from Vandeventer Avenue in St. Louis City; according to the I-64 FEIS, "was shown
to be very difficult and costly to construct" (http://www.thenewi64.org/feis/Chap_8/ChapterVIII_FINAL.pdf (http://www.thenewi64.org/feis/Chap_8/ChapterVIII_FINAL.pdf), Page 27/102)
4) EB left entrance from Forest Park Avenue
5) EB left exit to 11th Street
6) WB left entrance from Broadway

1) WB left entrance from MO 115/Natural Bridge
2) EB left exit to NB I-170
3) EB left entrance from SB I-170
4) WB left entrance from NB I-170
5) WB left exit to SB I-170
6) EB left exit to SB I-55
7) WB left entrance from NB I-55
The last two will be replaced with left entrances to/from I-44 when the new bridge opens
* I-70 (IL side)
1) EB left entrance from EB I-270
As part of the new bridge project, relocated WB I-70 will get a left entrance from WB I-64
* I-170
1) NB left exit to WB I-70
2) SB left entrance from WB I-70
3) NB left exit for Lambert Airport/right side of WB I-70
4) SB left exit for EB I-170
5) NB left entrance from EB I-70; could have been changed to a right side exit as part of a TIGER 2 grant
6) NB left exit to Boeing (service exit)
7) SB left entrance from Boeing
* I-255 (IL side)
1) SB left exit/major split with SB IL 3
2) SB left entrance from NB IL 3
* IL 3 freeway section near I-255
1) NB left exit to I-255 (real fun trying to weave to from the Palmer Road/Quarry Road entrance ramp
* Could count SB IL 3 to NB I-255 around Dupo, but I'm not going to since the section of IL 3 north of that intersection is semi-expressway
* MO 21/Blood Alley Replacement Freeway
1) Left entrance from Old 21 just south of MO 141; this one is one of those fun added lanes on the left, current right hand lane drops at the next exit

In Fairfield County, CT (total of 5):
- I-84 exit 3 (x2)
- I-84 exit 7 (x2)
- CT 8 exit 6
All are freeway to freeway. One is a major split and thus only sort of counts.
In Westchester County, NY (total of 18):
- I-684 exit 1 (x2)
- Hutchinson River Pkwy to I-684 connection (x2)
- Hutchinson River Pkwy exit 15 (x2)

- I-87 exit 8
- Bronx River Pkwy/Sprain Pkwy split (x2)
- Taconic Pkwy/Sprain Pkwy split (x2)
- NY 9A/100 at NY 117 (x4)
- NY 9A/US 9 split by Croton-Harmon
Nine of those are freeway to freeway, five are freeway to parkway with lights. Twelve of them are major splits and thus only sort of count.
In New Haven county, CT (total of 18, soon to be 15):
- CT 8/I-84 interchange (x7)

The DOT finished it's study of the I-84/CT-8 interchange, if you look at Concept 7, it has one lone left on-ramp from I-84 EB to CT-8 NB. Ugh!
http://www.ct.gov/dot/lib/dot/documents/dpolicy/WINS/Conceptual-Alt-7.pdf
But Concept 8 is the best!
http://www.ct.gov/dot/lib/dot/documents/dpolicy/WINS/Conceptual-Alt-8.pdf
If it is more than one lane like a two lane exit, would you consider that a split or a left exit??
or does it depend if the split is striped with an option lane or not??
Hampton Roads:
- I-64 westbound at VA 143 (Williamsburg Business Route)
- I-64 westbound at I-564
- I-64/564 HOV entrance/exits

- I-64/264 HOV entrance/exits
- I-64 westbound onramp from VA 168 (Tidewater Dr)
That about sums it up for interstate interchanges. Might be a few more associated with the US 58/VA 164 interchange or Bowers Hill.
Discounting freeway-to-freeway connections, I can't think of any on Kentucky's interstate system.

I'm proud to live in a state which does not have a single left hand exit or entrance on a mainline interstate. The only left exits are those from where an interstate ends and splits (such as I-93's terminus, splitting into ramps to I-91 North and South or I-189's terminus, but both ramps enter on the proper side of the interstate).
My closest left exit would be the one on I-89NB just outside of Concord NH, or Exit 27 on I-91SB near Greenfield MA.
Birmingham, AL's I-20/59 - I-65 interchange has the following left-lane exits: I-65 NB to I-20/59 WB/SB, I-20/59 WB/SB to I-65 SB, I-20/59 EB/NB to I-65 NB , and I-65 SB to I-20/59 EB/NB are all left exits, with corresponding left entrances.

Yes, you're correct. Don't forget I-80 EB's left entrance from US 46 at Exit 47A and all the mess at the GW Bridge.
In eastern CT:
I-95 NB at exit 86 (CT 184) in Groton
I-95 SB at exit 87 (CT 349) in Groton
I-395 SB at exit 78 (CT 32) in Montville
I-395 NB at exit 98 (CT 12) in Thompson
and I guess I-95 NB exit 76 (I-395) is one now, but of course that used to be the mainline.
Both of the I-95 ones also have left entrances.
In Rhode Island I can only think of four:
I-95 NB at exit 11 (I-295) in Warwick
I-95 SB at exit 9 (RI 4) in Warwick
US 6 WB at RI 14 in Providence
RI 37 WB at exit 4A (I-95 SB) in Cranston
The only left entrances I can think of in RI are:
US 6 EB from RI 14
I-295 NB from RI 37 EB
RI 37 EB from I-95 SB
The Grand Rapids metro area has a few.
In the interchange between I-196 and I-296/US 131 there are the following left exits that become left entrances:
NB US 131 to WB I-96
SB US 131 to EB I-96
EB I-196 to NB US 131
WB I-196 to SB US 131
There are left entrances at:
EB M-45/Lake Michigan Drive to EB I-196
WB M-45 to WB I-196
WB BS I-196 to WB I-196
the east side of Chicago Dr to WB I-196
M-37/Alpine Ave. to EB I-96
WB M-11 to WB I-96
SB BUS US 131 to SB US 131
WB M-6 to WB I-196
There are left exits at:
WB I-196 to M-11/28th St/Wilson Ave
WB I-96 to WB I-196
NB US 131 to I-96 (using I-296) with a a left entrance on WB I-96 from I-296
NB I-296 to M-37/Alpine Ave.
NB US 131 to Wealthy St. (with a left entrance to NB US 131)
I can think of thousands of left exits near me but only a handful of right exits :ded:
I honestly don't think Huntsville has any left exits at all (primarly because I-565 was built in the 80's and 90's after left exits had been discouraged). The closest ones I can think of to me would be I-20/59/65 interchange in Birmingham, as sglaughlin mentioned, or I-24/59 junction close to Chattanooga, which has left exits for I-24W->I-59S and I-59N->I-24W. Same interchange configuration for I-24/I-75, I-24/I-40 (both interchanges), and I-65S/I-40.
I'm having trouble thinking of any left exits on West Virginia's interstate system, as well, excepting freeway-to-freeway connections.

Well for those of you from the UK or other places that drive on the left, I think listing right exits would be appropriate.

There's a left entrance from 36th to I-77 north in Charleston. Other than that, when the WV Turnpike ended at a trumpet there were technically left exits and entrances from and to the main I-77 path.
Around Richmond: (first three both)
I-295 NB to I-95 NB(Exit 43A)
I-95 SB to I-295 SB(Exit 84A)
I-95 SB to I-295 NB(Exit 46)
I-295 SB to I-95 SB (left entrance south of Petersburg, not really a left exit(or counted as an exit but the exit to I-95 NB is though) as the mainline basically merges onto it even though I-295 SB ends here)
Salem/Roanoke: (both, second due to the end of the road)
I-81 SB at I-581/US 220 SB(Exit 143)
I-581/US 220 NB to I-81 SB
Mn/DOT has been actively trying to remove left exits as interchanges are reconstructed. Recently removed have been SB I-35W to EB MN-62 and NB I-35W to WB MN-62/NB MN-121.
Still remaining (off the top of my head)
WB MN-62 to WB US-212*
NB I-35W to "Downtown Exits" (fka MN-65)
SB I-35W to EB MN-36 and SB Cleveland Avenue
WB I-94 to 6th Street (downtown St. Paul)
NB MN-252 to WB MN-610
I am probably forgetting one or two others.
* For mainline MN-62 traffic, the movement to US-212 is more accurately described as a freeway split rather than a left exit. However, traffic entering 62 from US-169 or Gleason Road must cut across the 3-lane MN-62 and take a second-chance type left exit.
Baltimore:
almost all of them are on the Beltway.. :sombrero:
-@ I-95 exit 64 (though no more :no:)
I-695E to I-95 N
I-695W to I-95S
I-95N to I-695W
I-95S to I-695E
-I-695 exit 4
I-695 E to I-97S
I mean they just take a lane and a half to go nowhere but Annapolis...
-I-695 exit 31C
I-695E to MD 43E
-I-695 exit 36
I-695S to MD 702S
-MD 295S to I-195E
-I-83N to MD 25
-US 29 exit 22
US 29S to MD 100E
And that's just the ones I know of or see regularly.
Wisconsin:
Eagle Point Rd - left entrance only NB to US 151 near Dubuque
Mitchell Blvd in Milwaukee - all except WB exit are left
Old FW-FW interchanges (Zoo, Stadium, Hale, Mitchell (soon to be rid of them, sort of.))
Van Buren from I-794 - all except EB Entry
Lincoln Mem Dr from/to I-794 EB
Badger Interchange in madison (FW-FW)
WIS 29 W to I-39 S in Wausau (part of FW-FW)
Weigh Station on I-39 near Coloma is in the median
Though technically not a freeway exit - US2 W to US 53 S is a left "exit" (it's actually a protected left turn lane)
IIRC - Several Kansas Turnpike Service Areas are in the median
Illinois - I-94/US 41 South split (SB Only) before the toll road terminus

Birmingham, AL's I-20/59 - I-65 interchange has the following left-lane exits: I-65 NB to I-20/59 WB/SB, I-20/59 WB/SB to I-65 SB, I-20/59 EB/NB to I-65 NB , and I-65 SB to I-20/59 EB/NB are all left exits, with corresponding left entrances.
Those are all interstate interchanges. IS that what the OP is looking for? I imagine there are a lot of those and they aren't all that special. The one left hand exit I can think of in Birmingham is indeed on 20/59 like right in front of the Civic Center. 125A or B I think. You leave the interstate and it drops down to street level. Always causes a bottleneck in that area during rush hour because people just don't expect it.

Always causes a bottleneck in that area during rush hour because people just don't expect it.
There are also two left hand entrances to I-20/59 at the same interchange. I-59 South to I-459 south is a left exit and the ramp from I-459 North to I-59 South is a left entrance.
Oklahoma City
-all are freeway to non-freeway interchanges
I44 Westbound
Classen Blvd exit
Northwest Expressway exit
I44 Eastbound
Classen Blvd entrance
NOTE: the one mile stretch of I44 between Western and Northwest Expy has way too many on and off ramps. If you are westbound, there is a right exit, left entrance, left exit, right entrance, and left exit in less than one mile. The road was designed and built in the late 70's when I thought they knew better......
Quote from: mightyace on November 22, 2010, 10:04:16 AMWell for those of you from the UK or other places that drive on the left, I think listing right exits would be appropriate.
I think right-hand exits off motorways in GB are an exclusively Scottish phenomenon.
There's one on the Leeds Inner Ring Road, but it could be considered the A58(M) mainline (though there's diverge markings, not a lane drop). There's also 2 right merges and one right diverge on the top deck of the double deck section of the A167(M) in Newcastle - though both of them were planned to be freeway-freeway interchanges and IIRC there's lane gains/drops there. Both of these are piddling little motorways covering a mile or two around a city centre with no freeway connection to the rest of the network.
There's also the right hand entrance at M60 j25, though again, freeway-freeway interchange was planned there.
But other than that, I can only think of the two or three in Glasgow (M8 j15 and j17), though again, j15 was planned as a freeway-freeway interchange, and j17 was a freeway-expressway interchange. Both have lane drops.
Now it's been modified, does the A56/A682 have a right merge or diverge, rather than being left exit/entrance for the A56 to/from the north?
Northern California...
West Sacramento, I-80 at US 50 (result of I-80 being moved off the mainline of US 50 and onto what was I-880). For a few years, I-880 was a left exit off of I-80 in Foothill Farms, in anticipation of the never-finished I-80 realignment (that would've had it continue as the left mainline, the lanes of which are now used as light rail right of way).
Sacramento, Route 99 and Business 80 (originally I-80) at US 50.
San Francisco...in addition to the ramp from I-280 SB to US 101 SB, the ramp from I-280 NB to US 101 NB also does this (this was once the US 101 mainline). Marina Boulevard exits off the left from US 101 south in the Presidio.
On I-80 itself, the 7th Street and 5th Street ramps from the Skyway are both left exits.
US 101 southbound to I-80 east is a left exit, though at one point 80 did continue west of there.
I-580/I-880 exits from the left of I-80 westbound at the MacArthur Maze likewise, thanks to the 1984 extension, the exit for I-80 west from I-580 west is a left ramp (though this was once the US 50 mainline). At the Benicia Bridge's north end, I-780 exits from the left of I-680, but this was originally the 680 mainline until 1976.
I-580 exits off of the left of I-5 in Vernalis; originally, 580 was to be the 5W western suffixed branch of the mainline interstate, though the numberings had changed by the time the route was built.
On I-580 west in Castro Valley, 238 comes off on the left while 580 west takes the right lanes to continue onto the MacArthur Freeway.
Due to the reconstruction of the Central Freeway, at Van Ness Avenue for the last two decades, US 101 continues on the right while the left hand lanes lead to surface streets.
I think everyone has forgotten about this, the 295/76/NJ42 mess south of camden, the exit for I-76 exits left on southbound 295, the left merge from 76 once you stay on 295, etc.

I-405 North in Portland is practically an entire left exit in itself! From I-5 North to I-405 North is a left exit, not to mention the very first exit (SW Naito Pkwy) is a left exit. Continuing on I-405 North, the next left is US 30 West, which is then followed by the US 30 East exit (technically just a movement to I-5 South). Other examples of a left exit in the Portland metro area:
I-5 South -> I-405 North
I-5 South -> Mt. Hood Freeway (the ghost ramp still exists)
Outside of the metro area, I-84 at Multnomah Falls (both directions)
Two you missed: US 26 (Sunset Hwy) east to I-405 north and to SW Market St -- two left exits in the same interchange!
And I-84/US 30 west to I-205 north/south, as the signed routes exit the mainline.
Few more
New Jersey:
I-80 East to I-280 East in Parsippany
Virginia:
US 17 South has a left entrance onto I-66 East in Faquier County
I-81 South to I-581 South in Roanoke
US 460 West to US 460 Business West in Christiansburg
Filling gaps...
I-94 EB to MN-280 NB
I-94 WB to I-35W SB
That goofy interchange between Snelling Ave and I-694 where NB and SB Snelling Ave have left exits to go WB and EB respectively and each merging onto the freeway from the left.
WB MN-36/SB MN-95 to SB MN-95
NB US-151 to NB BUS US-151 in Beaver Dam, WI
Heres one, the left hand parking lot on the atlantic city expressway in NJ. http://maps.google.com/maps?q=atlantic+city+NJ&oe=utf-8&client=firefox-a&ie=UTF8&hl=en&hq=&hnear=Atlantic+City,+Atlantic,+New+Jersey&ll=39.388547,-74.506917&spn=0.004867,0.013078&t=h&z=17
In the Jackson area, I-55 northbound to Woodrow Wilson Boulevard is the only freeway-to-non-interstate with a left exit. There's also a left exit from Woodrow Wilson to I-55 north. I-20 west used to have a left exit to State Street, but a major reconstruction project has taken that lane away. Other left-turn exits from the interstates:
I-55 northbound to I-20 westbound
I-20 westbound to I-55 southbound
I-20 eastbound to I-55 northbound (just past the Pearl River/Rankin County line)
I-20 eastbound to I-220 northbound
I-220 southbound to I-20 eastbound
I-220 northbound to I-55 northbound
Before the Stack interchange was built, there used to be a left exit to get from I-55 south to I-20 east.

Discounting freeway-to-freeway connections, I can't think of any on Kentucky's interstate system.
There is a left exit on I-264 westbound at Dixie Highway southbound (US 31W/60) (Google Maps calls it Exit 8B, but I think it's really 8A). Yes, your "favorite" part of Kentucky!
As for Tennessee, there's the I-40 eastbound ramp to US 25W/70 south/east in Newport (Exit 432B), and other than freeway-to-freeway that's technically about it. I'm not counting the northbound Plough Blvd. on-ramp to I-240 west because Plough is practically a freeway. One could also argue that I-55 has left exits north and south in the cloverleaf interchange just east of the Memphis-Arkansas Bridge, but that's silly.

Had completely forgotten about that, since I am so rarely out on that side of Louisville. I think that is probably a vestige of when the Watterson Expressway was US 60 and it ended at Dixie, prior to the extension of I-264 as the Shawnee Expressway.
Surprisingly few in Louisiana. I know there have been more in the past. Will list freeway/surface connections only.
Baton Rouge (Virtually all clustered along the ancient 1950s era section of I-110 through downtown):

Well, two or three years ago, before Fix40, there was the left-hand interchange from I-40W to the James White Parkway/US 441 South Connector (Exit 388A), but that's gone now.
Quote from: CoelacanthMn/DOT has been actively trying to remove left exits as interchanges are reconstructed. Recently removed have been SB I-35W to EB MN-62 and NB I-35W to WB MN-62/NB MN-121.
However, the project you cite (the Crosstown Commons) added a new left exit (WB 62 to SB 35W) and perpetuated another (EB 62 to NB 35W).
QuoteNB MN-252 to WB MN-610
This one doesn't really count IMO since it's the terminus of 252. Similar to the I-93 Vermont example shadyjay cited earlier.
Quote from: wandering driveWB MN-36/SB MN-95 to SB MN-95
This one is moreso a route split than a bonafide left exit.
Some more not-yet-mentioned from the Twin Cities area:
- WB 94/694 to SB 494 in Maple Grove (left exit)
- NB 494 to WB 94 in Maple Grove (left entrance...I don't count the left exit since it's the I-494 terminus)
- EB 94 to NB 35W (left exit)
- NB 35W to EB 94 (left entrance)
- EB US 10 to NB 35W (left exit)
- WB 394 HOV ramps to MN 100 (left exits)
- EB 394 exit to 4th St (though there's an "END I-394" shield at the end of this ramp, I-394 actually ends at Washington Ave, so this is rightfully a "left exit")
- Conversely, the 3rd St ramp to WB 394 is a "left entrance"
- 12th St ramp to WB 94 in St. Paul (left entrance)
- SB 35E to Wacouta St in St. Paul (left exit)
- EB 94 to Mounds Blvd (left exit)
Of these, and relating to an earlier comment of JN Winkler, the first 6 are at system (fwy-to-fwy) interchanges, while the others are at service interchanges.
We also have some in the DC area. Excluding weird funkiness caused by cancelled freeways and the HOV ramps along 95/395 and 66:
- SB I-95 to SB US 1 near Woodbridge (left exit)
- US 1 to the Inner Loop (SB I-95/495) Thru Lanes in Alexandria (left entrance)
- NB I-395 to NB US 1 at the 14th St Bridge (left exit)
- SB I-395 to SB US 1 near the Pentagon (left exit)
- WB VA 27 to SB I-395 (left exit)
- NB GW Pkwy to Memorial Bridge/WB US 50 (left exit)
- Memorial Bridge to NB GW Pkwy (left entrance)
- Memorial Bridge/EB VA 27 to SB GW Pkwy (left entrance)
- Memorial Bridge/NB GW Pkwy to WB US 50 (left entrance)
- 10th St to EB US 50 in Arlington (left entrance)
- EB US 50 ramps at Courthouse Rd in Arlington (left exit and left entrance)
- Key Bridge to NB GW Pkwy (left entrance)
- NB GW Pkwy to WB Sprout Run Pkwy (left exit, but also arguably a "route split" since Sprout Run was the original terminus for the GW Pkwy)
- Maine Ave SW to NB I-395 (left entrance)
- SB 9th St SW to NB I-395 (left entrance)
- NB I-395 to C St SW (left exit)
- EB US 50 to NB BW Pkwy (left exit)
- Inner Loop (NB I-495) to WB I-66 (left exit)
- EB I-66 to Inner Loop (currently a left entrance, will become a right entrance after Beltway HO/T lane construction is complete)
- Inner Loop to WB VA 267 (left exit and left entrance)
- Outer Loop to EB VA 267 (left exit)
- Inner Loop to I-270 SPUR (left exit, though could also arguably be considered a "route split" given traffic volumes)
- I-270 SPUR to Outer Loop (left entrance, same argument as above)
The following are all in the area where I-270 meets the I-495 Beltway and MD 355/Rockville Pike:
- SB I-270 to the Inner Loop (left entrance, also arguably a "route merge" given traffic volume)
- SB MD 355 to the Inner Loop (left exit and left entrance)
- NB MD 355 to the Outer Loop (left exit and left entrance)
- NB MD 355 to NB I-270 (left exit)
- SB I-270 to SB MD 355 (left exit)
There are also a few scattered slip ramps between the Dulles Airport Access Road and the tolled part of VA 267. These are typically "left exits" along WB VA 267 and "left entrances" onto EB VA 267.
There's a left exit on US-10 in Midland, Michigan for traffic wanting to get onto the BUS US-10/M-20 freeway. :coffee:

Don't forget I-85 Northbound to I-985 Northbound is a left exit.
Also in metro Atlanta:
- I-75S to I-85N is left exit to right entrance
- I-285S to GA 400S is right exit to left entrance
- I-285N to I-20W is left exit to right entrance
Also, with I-75/85 N split in Midtown, I-85 splits to the left even though it goes NE and I-75N splits to the right even though it goes to the NW.
I'd forgotten about those, jdb1234 and Grzrd. Additionally, I-285 East to S.R.400 North is a very dangerous right lane exit to left lane entrance, due to the design of the interchange. Hopefully, GDOT/SRTA will get to fixing it one day.
The Brookwood Interchange, especially northbound, is a clusterpluck anytime of the day. :-(

The state of Nevada has no left entrances or left exits.
There used to be one: the WB Lake Mead Blvd to SB I-15 onramp in North Las Vegas used to be a left entrance ramp. The left entrance was removed when the interchange was reconstructed as part of NDOT's I-15 North design-build project that finished last year. (I'm not overly thrilled with the final design of that interchange...but the left ramp was removed so that's something.)
Interstate 81 South has one at Exit 180A to US 11 South near Natural Bridge,VA.
