NEW ORLEANS -- The mysterious bubbling swamp in Assumption Parish that turned into a sort of soupy sinkhole actually shut down a nearby highway this weekend.
About 100 homes were evacuated when the sinkhole started spreading.
It caused cypress trees to topple and even bent a natural gas pipeline. That's when officials shut down Highway 70, and started work to depressurize the pipeline.
Officials aren't sure, but say the problem could be connected to a nearby fault line or a collapsed salt dome.
