US 1 in GA has the St. Mary's River with FL and the Savannah River with SC.
US 1 in NJ has the Delaware River with PA and the Hudson River with NY.
US 1 in ME has the Piscataqua River with NH and the St. John River with NB Canada.
US 301 in GA has the St. Mary's River with FL and the Savannah River with SC.
US 64 in AR has the Arkansas River with OK (though not a continuous boundary, but the state line does cross where the US route crosses the river) and the Mississippi River with TN.
I-95 in GA has the St. Mary's River with FL and Savannah River with SC.
I-95 in NJ has the Delaware River now with PA and the Hudson River with NY.
I-78 in NJ has the Delaware River with PA and the Hudson River with NY.
US 46 in NJ at both terminuses is the Delaware River and Hudson River.
Any others that end at rivers or have state lines at both ends at rivers? Could also be state designations too.
I-64 enters Illinois from Indiana, crossing the Wabash River, and enters Illinois from Missouri, crossing the Mississippi River.
I-64 enters Indiana, crossing the aforementioned Wabash, entering from Illinois, and crosses the Ohio River, entering from Kentucky
I-64 enters Kentucky, crossing the aforementioned Ohio, entering from Indiana, and crosses the Big Sandy River, entering from West Virginia
Nebraska-Iowa-Illinois river crossings: US 20, I-80, US 30, US 6, and US 34
Example:
I-80 goes across the Missouri River in Omaha from Nebraska into Iowa & the Mississippi River in the Quad Cities from Iowa into Illinois.
US 60/62 enters Illinois from Kentucky via crossing the Ohio and from Missouri crossing the Mississippi, just north of the confluence of the 2 rivers, and 60/62 are in Illinois for about all of a mile
I-295 in NJ. And crosses the same river into 2 different states as a bonus!
I-85 and US 29 in Georgia, go from the Chattahoochee River border with AL, to the Savannah River/Lake Hartwell border with SC
I-10 and US 90 in Louisiana, go from the Sabine River (TX) to the Pearl River (MS)
US 10 in Wisconsin goes from the St Croix River (MN) to Lake Michigan (MI)
Should routes in Texas going from the Red River (OK) to the Rio Grande (Mexico) count? E.g. I-35
And DC is not a state, but I-95 and I-495 transit it with water boundaries at both entry points.

In the case of I-35, no. It ends in downtown Laredo, not at the Rio Grande. US 281 doesn't count in my opinion either, because only its spur crosses the Rio Grande. Which leaves us with just US 77 for that border.
Other than US 77, I think Texas has no highways that fit the criteria (although US 59's southbound lanes miss out on crossing the Red River in Texas by mere feet, and SH-6 crosses the Red River but ends a fraction of a mile from Galveston Bay if we're going to throw in larger bodies of water as well)
Pennsylvania is a challenge since only its jagged eastern border is defined by water (and there are no bridges to Ontario over Lake Erie).
That said, I found one interesting almost example:
At the southeastern edge of the state, US 322 enters Pennsylvania from New Jersey over the Commodore Barry Bridge, of course. Approaching the western border, US 322 snakes around the south end of Pymatuning Reservoir, and just as it reaches the Ohio line, the road crosses a small run (https://goo.gl/maps/61hmMJK275NQeRsk8) that leads into the reservoir. On this Street View (https://goo.gl/maps/fACEbz5o1psMYLBX7), you can see the PennDOT county/municipality signs along with the "END SR" marker right at the culvert.
So perhaps not a true water crossing and perhaps not exactly, precisely on the state line, but it's the closest example I could come up with for Pennsylvania (and a bit of a surprise at that).

US 67 in Illinois does something similar, as it crosses the Mississippi twice, at its southern Illinois point from Missouri, and at its northern Illinois point from Iowa
I-275 in Kentucky, as I-275 crosses the Ohio twice, from Indiana on the west side and from Ohio on the east side

Ferry at one end, and a ferry at the other end
MN:
I-94 crosses the Red River at the ND border in Moorhead and the St. Croix at the WI border at Lakeland/Hudson.
US 10 crosses the Red in Moorhead and the Mississippi St. Croix right at its confluence at Prescott, WI
US 53 crosses the Rainy River in I-Falls and the St. Louis River (St. Louis Bay) in Duluth
US 2 crosses the Red in East Grand Forks and St. Louis Bay in Duluth
Two that count because there's no further for them to go:
MN 1 begins at the Red and ends on the cliffs of Lake Superior at MN 61
MN 11 begins at the Red and ends on the shores of Rainy Lake at the Sha-Sha Resort

US 61 entered on the Mississippi from Wisconsin at La Crosse and entered Canada across the Rainy River.

Add US 18 to the list, except that it crosses the Big Sioux River from South Dakota, and crosses the Mississippi into Wisconsin.
US 136 enters Iowa by crossing the Des Moines River from Missouri. Less than four miles later, it crosses the Mississippi into Illinois.
As Iowa is the only state whose entire eastern and western boundaries are rivers, the premise of this thread is true of any route that crosses Iowa east-west.

US 1 in GA has the St. Mary's River with FL and the Savannah River with SC.
US 1 in NJ has the Delaware River with PA and the Hudson River with NY.
US 1 in ME has the Piscataqua River with NH and the St. John River with NB Canada.
US 1 can continue for NY as well. It has the Hudson with NJ, plus it has the Byram River with CT. CT also fits, as it has the Pawcatuck River with RI at the other end.
Eastern US 2 for VT crosses the uppermost portion of Lake Champlain into NY, and the Connecticut River into NH.
US 2 in Minnesota crosses into the state from North Dakota at the Red River of the North and then exits into Wisconsin at the St. Louis River. Continuing eastward, US 2 then exits into Michigan at the Montreal River, reenters Wisconsin at the Brule River and reenters Michigan at the Menominee. At one time, US 2 terminated in Sault Ste. Marie at the ferry across the St Marys River to Canada, which meant it fully transited three states, two of which twice, between water crossings.
US 8 in Wisconsin enters the state from Minnesota crossing the St. Croix River and then exits into Michigan by crossing the Menominee River.
US 10 in Wisconsin enters from Minnesota at the St. Croix River and exits on the SS Badger to Michigan.
US 61 in Wisconsin transits the state between crossings of the Mississippi River.
US 141 also transits Michigan between Menominee River crossings and transits Wisconsin between the Menominee and Brule rivers.
Probably too easy: The Trans-Canada Highway on Prince Edward Island.
Probably the most high-profile one for NY is I-95, which enters via the GWB and exits via the Byram River Bridge.
VT: US 4 enters from NY over the Poultney River, exits to NH over the Connecticut River
NH: NH 9 starts from VT 9 over the Connecticut River, becomes ME 9 over the Salmon Falls River

US 30 in Oregon. On its western terminus it begins at the south end of the Astoria-Megler Bridge, which crosses the Columbia. US 30 then crosses the Snake River co-signed with I-84.

Right. I didn't mention that because it was already mentioned in reply #5.
US 36 crosses the entire northern half of Missouri, from the Missouri River on the west side to the Mississippi River on the east. 136 is similar but doesn't quite make it to the Mississisppi in MO - instead, it briefly enters Iowa at the Des Moines River.
Also, I-495 counts not just for DC but for both Maryland and Virginia too

US 60/62 enters Illinois from Kentucky via crossing the Ohio and from Missouri crossing the Mississippi, just north of the confluence of the 2 rivers, and 60/62 are in Illinois for about all of a mile
Then US62 in Kentucky goes from there to crossing the Ohio River again into Ohio near Maysville.
Also, I don't think anyone has mentioned US52/US119 when it goes back and forth a couple of times over the Tug Fork between Kentucky and West Virginia.

How about US-50 in Maryland starting at the Atlantic Ocean and ending at the the DC line on the Anacostia River?
It might technically be a stretch because the Anacostia River isn't the boundary between DC and MD - it's simply that the northeastern boundary (i.e. Eastern Avenue at times) of DC happens to intersect US-50 very close to the Anacostia.
DC-MD: https://www.google.com/maps/@38.9186272,-76.9406061,18z
Furthermore, US-50 doesn't start on the Atlantic, but instead about 2 blocks inland: https://www.google.com/maps/@38.3307953,-75.0858148,18z

If the Anacostia DC-MD line counts, then you can also include US 50 in DC since it crosses the Potomac at the VA-DC line.
I think the only two US highways that work for Illinois are US67, which was mentioned earlier, and US50. I-64 also fits* this criterion for Illinois. Illinois doesn't have any state routes that fit the criterion, and I'm interested to see if there are any state routes anywhere in the nation that do.
*Edited to remove mention of I-70

Closest one I've found so far is IA9 which unfortunately jogs north before crossing the Big Sioux River into South Dakota. It crosses the Mississippi into Wisconsin at Lansing on the east side.
Edit: Well, the eastern segment of GA94 crosses into Florida on both ends over the St. Mary's River. It does continue with a disconnected route to the west, but that segment would at least qualify.
Double Edit: I saw that someone posted that up above and I missed it.

US 10 transits WI from the St Croix/Mississippi junction at Minnesota to Michigan across Lake Michigan on the S.S. Badger Ferry (Mentioned above)
US 9 transits NJ from the Delaware Bay (Cape May Lewes Ferry from Deleware to the George Washington Bridge to NY(C)
From Sioux City southward - many routes cross Iowa between the Missouri to the Mississippi (I-80, US 20, US 30, US 34). US 18 meets the Big Sioux and the Mississippi. US 136 cuts through Iowa for a short distance and meets the Des Moines River and the Mississippi. It then meets the Missouri on the other side of Missouri. US 36 meets the Missouri and Mississippi on the Missouri lines

I would say IL 13, IL 15, IL 146, and even IL 1 come close, as does that *thing* we call IL 110
The western end of IL 13 doesn't make it all the way to the Mississippi. Western end of IL 15 gets closer to the river, deep into East St Louis, but it still comes up just shy of the river
The eastern end of IL 146 ends at IL 1 just north of Cave-in-Rock and the Ohio River
IL 1's northern end is in the city of Chicago on Halsted St, and even Halsted ends before reaching Lake Michigan
IL 110/CKC's northeast end appears to be the Jane Byrne Circle Interchange - even if it continued on Congress Parkway, it still would end before it reached Lake Michigan, at Grant Park and Buckingham Fountain
IL 3 comes very close to having both ends on the Mississippi River, but it ends both sides just shy of the riverfront, both in Cairo and in Grafton
It's interesting that no one can agree on what "transit a state" means for routes that end not at the border but merely near it.
West Virginia has rivers all along the length of its borders with Ohio and Kentucky, and for a brief part of the Virginia border. US 52 enters West Virginia from Kentucky by crossing Tug Fork and exits to Ohio by crossing the Ohio River.

More accurate to say "re-enters." US 52 actually enters the state via a tunnel. But you already knew that.
One not mentioned yet (AFAICT): US 98 in Alabama. While the MS/AL border is a straight line, where US 98 crosses it happens to be coincident with the Escatawpa River bridge. Then US 98 crosses Perdido Bay into Florida.
Depending on the definition "transit", I would include I-96, M-72, M-55, M-142, M-46, M-53, M-29, M-25 in Michigan to start off.
I-10 in California, Pacific Ocean at west end, Colorado River at east end.

Along those lines, we had a
thread (https://www.aaroads.com/forum/index.php?topic=27705.0) a few months back about water crossings coincident with jurisdictional boundaries. There's probably more unsuspecting examples that could be found using that as a guide.
I'm going to stretch the definition of a water border a bit and mention I-70 in MO. The border crossing in St. Louis is obvious, Stan Musial Bridge over the Mississippi River. On the other side, the MO-KS border is about half a mile east of the Kansas River. The reason why I'm counting this is because it's a single bridge structure crossing both the MO-KS border and the Kansas River, with no exits to the small part of Kansas between those two. When a driver passes the last I-70 exit in Missouri and gets on the bridge, they cross both the state line and the river, and the next exit is on the "mainland" part of Kansas.
Speaking of I-70 in MO, are there examples of highways that have a water crossing on both entry points of a county? I was going to count I-70 and I-64 in St. Louis county, but forgot that St. Louis city is independent from the county, which disqualifies those 2 highways.
Minnesota has a few, not limited to:
I-494 crosses the Dakota/Hennepin line at the Minnesota River and the Dakota/Washington line at the Mississippi.
US 169 crosses the Hennepin/Anoka line at the Mississippi River and the Hennepin/Scott line at the Minnesota River.
MN 101 crosses the Wright/Hennepin line at the Crow River and the Sherburne/Wright line at the Mississippi.
MN 55 crosses the Hennepin/Wright line at the Crow River and the Hennepin/Dakota line at the Minnesota.
