Actually, there is a US 41 Little Alapaha River bridge, and it may even be historic. So that’s five bridges across the Little Alapaha River, four above the Swallet, and one below, before its Confluence with the Alapaha River.
The US 41 bridge is the first bridge listed by bridgereports.com for Hamilton County, mislabled as “US-41 (SR-6 & 25) over ALAPAHA RIVER OVERFLOW”. But at 30.52389, -83.01550, it’s much closer to the Little Alapaha River.
At more than a mile east of the Alapaha River, that’s a bit far to be overflow.
It’s also about a thousand feet east of where the USGS track for the Little Alapaha River crosses US 41. Apparently USGS was making a schematic trace of approximately where they think the river travels underground. (The USGS track also misses the actual location of the Little Alapaha River Confluence with the Alapaha River.)
You can sort of make out an empty river valley north of the bridge, coming down from the swallet, where most of the water most of the year goes into the Floridan Aquifer. And in google streetview you can see that valley.
South of the bridge, the aerial view shows the river turning sharply to the east before heading south. And that’s what we see in google streetview looking southeast.
The bridge itself turns out to be possibly historic, presumably because of how old it is:

Nonetheless, there is a US 41 Little Alapaha River Bridge.
You may have to refresh your browser (control shift R) to see it in that last map, if you were previously looking at the previous post about the Little Alapaha River.
