Crossing the same body of water twice or more

[hbelkins]

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.

Both of US 67's crossings are at an Illinois state line. It enters the state from the south crossing from Missouri, and leaves the state in the north crossing into Iowa.

Same goes for two of US 61's crossings, only Wisconsin is the state involved.

Québec A-73 crosses the Chaudière river thrice on 9 kilometres (5.5 mi.) : http://goo.gl/maps/LdOoY

R-131 crosses Noire river 5 times, and windingly parallels its meanderings at its head in a spectacular valley. Fun to drive.

R-132 has been crossing Matapedia river thrice for a short period of time (5-10 years now?), with 2 new arch bridges near Routhierville hamlet, a tiny paradisiac settlement accessible only by this covered bridge.

R-132 also crosses Mitis river two times, separated by 533 miles.

R-263 crosses Bulstrode river 4 times.

Those are the >2 crossings I can think of.

EDIT : minor corrections

One right in my back yard and I had forgotten about it.

The Mountain Parkway crosses the Red River four times -- three times in Powell County and once in eastern Wolfe County.

U.S. 119 (ADHS Corridor G) crosses the Little Coal River about 9 times between Danville, W.Va. and Alum Creek.

US 191 crosses the Gallatin River five times between Yellowstone and Bozeman.  Beautiful scenery and 70mph speed limit!

I-91 crosses the Connecticut River twice.

So does US 5.  MA 116 does thrice.  If you count a long exit ramp, I-84 crosses the Quinnipiac twice.  CT 8 crosses the Naugatuck River 7 times between Derby and Thomaston.  US 7 crosses the Housatonic River 6 times.  CT 4 and US 44 cross the Farmington River twice, while CT/MA 8 does 3 times .

US 23 crosses the appropriately named "Crooked Creek" 4 times in a span of about 3 miles in Waverly, Ohio

It doesn't have to be a river. Is there anything that crosses the Atlantic or Pacific Ocean a significant number of times?

Hiway 30 in western Iowa crosses the Boyer River 5 times, and the East Boyer 2 more times.

Prior to the construction of the Missouri River crossing at Blair Nebraska, Hiway 30 went south to Council Bluffs and crossed the Missouri there. That added another Boyer crossing, however, the river has been channelized and hiway 30 has been realigned in a few places, so I cannot tell if there was ever a time when 30 crossed the Boyer a total of 7 times (or more, LOL).

It would take some good ancient map detective work to figure that out.

The Queen Mary.

Not any more!

I think the QM2 now serves that function (at least in summer) of crossing Southampton - New York, back and forth with short cruises in between crossings. The QE and QV I think are used more for world tours and long cruises than trans-atlantic crossings.

US 71 crosses the Red River (the southern one  ) 3 times

[elsmere241]

I-40 in east-central Tennessee crosses the Caney Fork River I think five times in about two or three miles.

R-132 also crosses Mitis river two times, separated by 533 miles.

Clever, but I almost want to consider this cheating.
