I was curious as to how many instances there are of Interstate highways connecting to the same route on consecutive exits (excluding the two ends of route multiplexes and non-congruent exits).
The example I can think of is PA 50 and I-79 near Pittsburgh, where the Bridgeville and Heidelberg exits both connect to the same state route a few miles apart (although the Heidelberg exit does not mention it leads to PA 50).
I-65 has three consecutive US 231 exits in Indiana (193, 201, and 205). There is yet another US 231 interchange further north.
I-95 and US 301 in Virginia have a 2 1/2 consecutive exit sequence. Exits 45, 41 (with VA 35 & 156 also shown) and 37 (southbound only, northbound shows SR 623). There are more US 301 exits between there and the VA/NC line, but I don't remember any of them being consecutive.
I-75 in GA: Exits 263 and 265 are for Loop 120 (Marietta Parkway)
In Alabama:
I-65 Exits 130 & 142 are for AL 185.
I-10 Exits 27, 30, & 35 are for US 90 & US 98
Drivers going westbound on I-64 in Hampton will cross VA-134 at Exits 265B, 263, and 262. Interestingly enough, drivers going east will only see VA-134 once, at exit 263.
Also in Virginia...
I-64 and US 250 exits 99 and 107
I-77 and US 52 exits 64 and 66
I-81 and US 11 exits 39 and 44
I-81 and US 11 exits 175 and 180
I-85 and US 460 Bus exits 61 and 63

Also I-66 exits 72 and 73 (both for US-29).
In Missouri on I-29, Exits 65, 67 and 75 are all US 59, but the first two are ends of a multiplex over the Nodaway River. On I-35, Missouri exit 114 and Iowa exit 4 are both US 69.

This would rule out part of the following:
QuoteDrivers going westbound on I-64 in Hampton will cross VA-134 at Exits 265B, 263, and 262.
Namely 262 and 263, as I-64 and VA 134 are concurrent between those exits.

In Vermont, we have the following:
- I-89 in Colchester meets US 2 at both Exit 16 and Exit 17 (if VT 289 ever gets revived and built, it'll have an interchange with I-89 in between).
- Officially, I-91 and VT 9 at Exits 2 and 3 in Brattleboro. Signs might confuse some people, but VT 9 still officially goes through Brattleboro while it's a VT 9 truck route that follows I-91.
- Southbound I-91 and US 5 at Exits 3 and 4 (northbound, Exit 4 is at a side road).
- Not Vermont, but just across the Connecticut River, we have I-93 and NH 135 at Exits 43 and 44 northwest of Littleton.
- If you include multi-state routes and related to the above, you have I-93 and NH/VT 18 at Exit 44 in NH and Exit 1 in VT.
On the Wilbur Cross Parkway in CT Exit 57 is for CT 34 East, and Exit 58 is for CT 34 West. Exit 61 is for Whitney Ave. (SR 706) south, and Exit 62 is for Whitney Ave. north (SB only) Also on I-84 in Waterbury, Exit 19 is for CT 8 South, and Exit 20 is for CT 8 North. Farther up, and westbound only, Exit 35 is for CT 72 East, and Exit 33 is for CT 72 West (34 was eliminated). Also, the I-91 interchange is consecutively numbered with 51 for 91 North, and 52 for 91 South. In Manchester, Exits 63, 64 AND 65 are all for CT 30/CT 83. On I-91 northbound, Exit 28 is for US 5/CT 15 South, and Exit 29 is for North. Along I-95, Exits 13 and 14 are for US 1 (in both CT and RI), as are Exits 33 and 34. On I-91 in MA, Exits 20-24 are all marked for US 5/ MA 10. Although unmarked for Exit 10, the Mass Pike has 4 consecutive exits for US 20 (8, 9, 10, 10A).
North Carolina has:
I-40 and US 64 exits 162 and 168
I-85 NB and NC 7 exits 23 and 26
I-95 and US 301 exits 22 and 25
South Carolina has:
I-26 and US 176 exits 97 and 101
I-26 WB and US 78 exits 205 and 209 (US 78 is unsigned at the I-26 end of the exit 209 connector but is signed at the other end)
I-85 and SC 18 exits 95 and 96

In Louisiana:
I-20 and US 79 exits 3 and 5
I-20 and US 80 exits 5 and 8
(technically all 3 exits make reference to US 79 or US 80 which is the same highway, but never consistent to show both)
I-20 and LA 602 exits 173 and 182
US 90 and LA 662 exits 182 and 185
US 90 and LA 20 exits 189 and 194
I'm sure there will be consecutive LA 182 exits as well in the Berwick/Patterson area of Future I-49
Nearly every exit along DE 1 between the C&D Canal Bridge and the southern point of the limited access portion of the road exits directly onto US 13, or is a short drive to US 13, with most of the exits signed for US 13. The Exit for DE 299/Middletown may be the lone exception.
Oops one more for Louisiana and not sure if it counts.
Southbound US 167 expressway in Pineville:
LA 107, LA 1250: Marksville & Shamrock St.
then
LA 1250 Shamrock St, Downtown (ha!) Pineville
For whatever reason when all of these signs were replaced they decided to put LA 1250 on both exits, which is stupid, because the 2nd Shamrock exit just makes an enormous trek down the frontage road and u-turns back. So LA 1250 doesn't cross twice, although the 2nd exit is really Spur 1250

I-81 and US 11 in New York.
Exits 1 and 2 are almost directly for US 11.
Exits 5, 6, 7, 8, 9 and 10 all directly intersect US 11. This is every exit between Binghamton and Cortland, and more than half the distance to Syracuse from Binghamton.
After Cortland, Exits 14 - 16 all directly intersect and Exit 17 is labeled for S Salina St. We're within Syracuse city limits now. FWIW, I-81 between Exit 14 and Exit 16 looks like it was probably originally signed as US 11.
There's likely a good string of them north of Syracuse.
Dylan T. Lainhart / Binghamton, N.Y.
In Saint Cloud, MN, I-94's exit 171 is for CSAH 7 and CSAH 75. The next exit, exit 73, is also for CSAH 75. To eliminate confusion, this exit is only signed with it's street name, Opportunity Drive.
Granted this one is somewhat open for debate and only existed since 1988-89; along US 1 North in Peabody, MA; there are technically 2 consecutive exits for I-95 North:
The first one's right at the Peabody/Lynnfield line where it multiplexes w/MA 128. While the exit and split ramps are only signed as 128 NORTH; one is actually on I-95 North until at least Exit 45 (the 95-128 split), which roughly 3/4 mile away from the ramp merge onto I-95/MA 128 North.
The second one is about a mile further north along US 1 and is a direct ramp to I-95 North (beyond 128) near the Peabody/Danvers line that was originally constructed in the mid-1970s when I-95 was extended southward from its original 1950s terminus at Danvers/Topsfield.
In southeastern, PA (Bucks County) I-95 has two consecutive interchanges w/PA 413; granted the new connection w/the PA Turnpike (I-276) and re-route will change all that but the current scenario still applies.
Kentucky:
I-75:
exits 15 and 25 are for US 25W
exits 59 and 62 are for US 25
Mountain Parkway:
exits 40 and 43 for KY 15 (Exit 43 is signed "To KY 15" since it's actually for Spur KY 15)
exits 57 and 60 are for KY 191 (Exit 57 co-signed with KY 205; Exit 60 co-signed for KY 134 and is a partial exit)
West Virginia has two consecutive exits for WV 25 on I-64 in the Charleston metro area but I can't think of their exit numbers off the top of my head.
Do different exit numbers for different directions count? If so, then...
Exit 20B on I-355 northbound is for US-34, Odgen Avenue. Exit 19 on I-355 southbound is for the same. Funny thing, Exit 20B leaves I-355 south of Exit 19. And yes, they are two halves of the same diamond interchange.
Exits 403 and 407 on I-5 near Santa Nella, CA both serve Route 33, the first one being the 33/152 cloverleaf, the second one as Santa Nella Road heading out towards Gustine.

The example I can think of is PA 50 and I-79 near Pittsburgh, where the Bridgeville and Heidelberg exits both connect to the same state route a few miles apart (although the Heidelberg exit does not mention it leads to PA 50).
Actually... a year or two ago the NB signs for the Heidelberg exit were replaced with ones that DO have the PA-50 shield on them. The overhead sign structure right before the Bridgeville exit has signs for both exits on it, and I remember thinking "WTF" at first when seeing it.
GSV is recent enough that it has it: http://goo.gl/maps/SKslD (http://goo.gl/maps/SKslD)
As of a week ago, the signs heading SB still don't mention PA-50 for Exit 55.
Pretty much everything with I-91/US 5.
MA 213 has exits 3 and 4 both be MA 113.
I-93 and all these:
NH 18, NH 132, US 3, US 302, NH 135, NH 116, NH 142, MA 28 (northbound)

I was curious as to how many instances there are of Interstate highways connecting to the same route on consecutive exits (excluding the two ends of route multiplexes and non-congruent exits).
I-65 and US 31 do not technically multiplex in extreme southern Indiana as US 31 is routed along the access road, so Exits 4, 2, and 1 all connect directly to US 31.
I-10 has numerous instances of this between Fort Stockton and the current western end of US 290 where the old 290 alignment runs more or less parallel but not quite close enough that TxDOT demoted it to frontage road status. However, it isn't always consistent about whether the number given to the old highway is signed on the exits.
Exits 4-6 on I-390 are all for NY 36, and Exits 27-29 on I-490 are all for NY 96.
I-70 in Ohio, exits 213 and 215 are both for US 40.
I-64 in West Virginia, exits 175 and 181 are both for WV 92 AND US 60 (although the latter could be discounted on the grounds that it begins a multiplex at exit 181 going into Virginia). In addition, exits 50 and 53 are both signed for WV 25; and exits 15-28 are ALL signed for US 60.
The Palisades Parkway in NJ has both Exits 3 and 4 connecting to US 9W. Interestingly enough, they're both signed exactly the same with RT 9 W on its guide signs.
Can we count it over two states on I-91? Both Exit 28 in Bernardston, MA and Exit 1 in Brattleboro, VT (~12 miles apart) involve US Route 5. There's no other exit between those two.
On a side note, VT Exit 2 is a mile or so west of US Route 5. VT Exit 3 involves US Route 5 (at VT/NH Route 9 East). VT Exit 4 is also for US Route 5.

I-91/US5 EVERYWHERE.
Over state lines, RI/MA-146 has three consecutive interchanges with 146A. The Forestdale exit in RI and Exits 1 and 2 in MA.
Two instances on the Kansas Turnpike (which consists entirely of Interstate routes): Exits 33, 39, and 42 are all signed for US 81, and Exits 202 and 204 are both signed for US 59. There are a few caveats, however: Exits 33 and 39 don't go directly to US 81, Exit 202 doesn't go directly to US 59, and Exit 202 is only signed for SB US 59, although both directions of US 59 can be accessed just as easily from Exit 202.
East Peoria, IL has a half-example of this. Exit 95A on I-74 is a full diamond with Main Street, which carries US-150 and IL-116. Exit 95B is eastbound only, and it goes to eastbound Camp Street, which carries US-150 and IL-8.
I-78 and NJ 173 going WB. Exits 13,12, 11, and 7 connect directly (and are signed of course) to NJ 173. Going the other way you have Exits 7, 11, 12, and 15 in a row, but 11 and 12 are only signed NJ 173 as the two ramps really connect to adjacent roads.

As does Exit 2. Exit 1 is pretty darn close, and then you also have the connection at its southern terminus.
I-295 in Maine has several cases of US 1 being the same exit more than once in a row. Exits 9-10 between Portland and Falmouth, exits 15-17 in Yarmouth, and exits 24-28 between Freeport and Brunswick.
Further downstate, I-95 exits 2 and 7 lead toward US 1 as well.

But does it ever consecutively? Off the top of my head, the only time it might would be at the ends of a concurrency, which the OP excluded.

I thought about Exit 2, but going NB you have to use another road to pass under the PIP. Yeah, true SB does indeed tie into US 9W,and also like you said that Exit 1 is almost. If Exit 1 did not connect with CR 505, you would have a perfect 5 going SB.
Both Exits 364 and 366 along I-25 in New Mexico are signed "NM 161-NM 97/Watrous/Valmora". Only 161 actually intersects the interstate, at both exits, and 97 intersects 161 near the more northerly exit. http://goo.gl/maps/k6VVR

Personally, I'd call that "road" just part of the ramp, though maybe the fact that it serves the park access as well muddies things slightly. Regardless, the exit's signed as 9W, and it's far more direct access than having to make a median U-turn and cross over both lanes of traffic at Exit 3.
