Members of the Florida Wildlife Corridor Expedition emerged from a swamp south of Interstate 4 late Thursday and crossed underneath the busy highway.
There, they spotted tracks of wild pigs and deer and looked at photos of bobcats, otters and raccoons taken by remote-control cameras set up at the crossing.
As cars zipped by overhead, expedition member Joe Guthrie said it was tough traversing the preserved stretch of land between Tampa and Orlando.
"We've made 13 miles in five days, four days, sometimes you couldn't see five feet in front of you and just had this wall, just a mass of vegetation," he said.
While they've encountered tracks and evidence of a number of animals, they've seen more than their share of snakes.
"A lot of cottonmouths," Guthrie said. "Every step, you've got to be conscious of where you're putting your foot."

Expedition members are doing the week-long mini-trek to bring attention to the narrow swaths of land wildlife use to migrate through Florida. They're continuing to paddle along Reedy Creek Friday, passing in the shadow of Walt Disney World.
They'll speak at an event Friday afternoon at Lake Louisa State Park in Lake County.
