Here is one possible example of what you seem to be describing … way 84255726
Within Florida's Oleno State Part, the Santa Fe River vanishes into a sinkhole. It then reappears at River Rise Preserve State Park. the route, as depicted in the way (a mile +/-), is the presumed subterranean path. The way is tagged as tunnel=yes, which seems odd, yet descriptive (but as a tunnel, it would be natural and not man-made).
