Crossing the same body of water twice or more

[NWI_Irish96]

As far as the Interstates in Michigan go, it's hard for me to fathom that anything could beat I-96's four crossings of the Grand. I'm more than willing to be corrected if I'm wrong.

I-196 crosses it twice in Grand Rapids as well.

I counted I-15 crossing the Virgin River 6 times between St. George, UT and Beaver Dam, AZ through the Virgin River Gorge. The gorge itself has 4 crossings (if you don't count a short portion where the river goes under the highway).

I-35 crosses the Mississippi River twice.

I-35 crosses the Mississippi River twice.

I-69 almost crosses the Rio Grande thrice.

Mention must be made of I-75 in downtown Dayton, Ohio.  It crosses the Great Miami River 5 times in 5 miles!  http://maps.google.com/maps?gl=us&om=0&ie=UTF8&ll=39.761311,-84.190292&spn=0.096198,0.156212&z=13

I-75 also crosses the Great Miami River a 6th (!) time (just north of Exit 78, south of Piqua, OH) and then a 7th (!!) time (around mile marker 89, just south of Sidney, Ohio).

In total, 7 crossings in about 38 miles.

M-89 crosses the Kalamazoo river six times.  Twice in Plainwell, once in Otsego, two times in Allegan and once just west of where M-89 and M-40 split East of Fennville.

You're right that it crosses six times, but technically in Plainwell M-89 only crosses the river proper east of downtown while crossing its mill race west of there. Of course, M-89 crosses the Kalamazoo on the Washington Avenue bridge which spans the consolidated railroad tracks in Battle Creek right before it ends at Dickman Road.

Ohio Route 4 crosses the Great Miami twice. Once as it leaves Middletown, and a second time as it enters downtown Dayton.

U.S. 50 crosses the Potomac River between Gorman, Maryland and Gormania, West Virginia, and again between Arlington County, Virginia and the District of Columbia.

**EDIT: Is this potentially the only river that is crossed multiple times by both an odd and even US highway with none of the crossings being multiplexes of the two?**

Nope. US-2 crosses the Mississippi River twice, and US-61 crosses it four times.

US 4 crosses the Merrimack River twice.

US 3 crosses the Merrimack River thrice.

[getemngo]

It's a minor river, but US 41/M-28 crosses the Carp River in Negaunee Township and again in the City of Marquette near the mouth next to the city water treatment plant and Marquette Branch Prison.

US 41 in Michigan also crosses the Sturgeon River twice: near Canyon Falls, south of Alberta, and again at its mouth south of Chassell. Which leads to the question: how many highways cross multiple bodies of water more than once?

Algoma Ave north of Grand Rapids crosses Cedar Creek 6 times and Little Cedar Creek once. Four of the crossings happen in half a mile, and almost all of them are signed! Somebody was really committed to making that road straight, environment be damned.

[MASTERNC]

The PA Turnpike (I-70 overlap) crosses the Juniata River twice near the Bedford interchange.

I-93 crosses the Merrimack River more than once and Pemigewasset River more than once.
However, the Pemigewasset flows into the Merrimack.

US 9 crosses the Hudson River twice, once on the George Washington Bridge and once near Albany.

[Chris19001]

US 422 crosses the Schuylkill River five times, three of the crossings are located near the Interstate 176 interchange.

Better make that six times.  You forgot the Betzwood Bridge at Valley Forge on top of the two crossings around Pottstown.

[brownpelican]

I-70 crosses the Missouri River twice: at Saint Charles and again near Booneville.

[spooky]

I-95 crosses the Charles River three times between the Dedham-Needham town line and the Newton-Weston town line. A driver exiting I-95 North onto the Mass Pike crosses the Charles three more times before they get to the toll booth in either direction, then once more on the Pike if they are traveling eastbound.

[CNGL-Leudimin]

The Chinese expressway G50 crosses the Yangtze river three times.

The French autoroute A7 crosses the Rhone river three times.

Also in the Boston area I-93 crosses the Mystic River at least twice, the first being the Bunker Hill Bridge.

That's the Charles...

Crap!  It's the Tobin Bridge that goes over the Mystic.

TX 71 crosses the Colorado River at least five times between Columbus, TX and Austin, TX.

I-39 crosses the Wisconsin River twice, once near Portage, WI and the other in the south suburbs of Wausau, WI (Rothschild, to be exact).  Its continuation (US 51) then crosses it again just south of Merrill, WI and again in the Minocqua-Woodruff (Lakeland), WI area.

You missed I-39's southern most Wisconsin River crossing with 90 & 94 for a total of 5 crossings for the I-39/US 51 corridor.  Also that last one is in Tomahawk.

The winner in Wisconsin has to be WI 131 and the Kickapoo River.  I count 32 crossings between Soldiers Grove and Tomah.  It would have been even more if a section of 131 hadn't been relocated north of La Farge in the 60's for a proposed dam that never materialized.  (Looks like 5 more crossings.)

The Kickapoo is Wisconsin's largest river that exists entirely within the "Driftless Area", a region in the southwestern part of the state that was spared by the glaciers.  As a result the Kickapoo has a well developed valley and a gracefully meandering channel that frequently butts up against the valley walls.  From a road construction stand point, it's much like a mountain valley in that it's easier to have a highway bridge the stream numerous times to keep the road on flat ground.  And since WI 131 follows the entirety of the Kickapoo River the result is 32 meetings of the same stream and the same highway.

You also missed where Us 51/I-39 crosses 3 bays of Lake Du Bay between Stevens Point and Wausau. Lake Du Bay is an impoundment of the Wisconsin River.

Considering the nature of the Platte River in Nebraska, I-80 crosses it too many times to bother counting.

The Mississippi is crossed multiple times by US 61, US 67, US 169 and by US 2 and US 52, although US 52's even-numbered nature is dubious at that point.

In Nebraska, the Elkhorn River crosses US 275 5 times alone, US 20 2 times alone (3 if you count the South Fork Elkhorn River), and once on their multiplex.
