If you live anywhere off South Park Loop Road, you've been hearing trucks on Feedground Road since the second week of August. Heavy ones, moving steady, kicking up dust past the turnoff to the wildlife habitat area. It would be easy to assume that whatever's making that noise is also what closes the road completely for four days starting next week. It isn't. Two different projects are running on that half mile of road right now, for two entirely different reasons, on two entirely different sets of rules about whether you can still get through.
Knowing which crew is which is the difference between planning around a closed gate and driving past one you didn't expect.
Two Crews, One Road, No Relation
The first project has been underway since August 10. The U.S. Army Corps of Engineers, Walla Walla District, is rebuilding the levee along the Snake River inside the South Park Wildlife Habitat Management Area, pulling out old riprap and bringing in new stone to shore up the bank. That work runs through the end of September, and the truck traffic that comes with it has been the background hum of the neighborhood for three weeks now. Crucially, the area stays open to the public through all of it. Nobody's turning you around at the gate for the levee work. You just share the road with the equipment.
The second project is unrelated, run by a different agency, and it behaves differently. The Wyoming Game and Fish Department is improving the road into the Jackson Housing Project, and that work closes the WHMA turnoff outright, not just to slow traffic but to all vehicle and walk-in access. It's happening in two separate stages. The first, focused on grading and swapping out two cattle guards, ran August 19 through 22. The second stage, which is the paving itself, starts September 3 and is expected to wrap by September 6.
| Project | Who's running it | Timeline | What actually closes |
|---|---|---|---|
| Levee and riprap repair | U.S. Army Corps of Engineers | Aug. 10 through late September | Nothing. The WHMA stays open throughout, traffic just shares the road with equipment |
| Housing project road paving | Wyoming Game and Fish Department | Aug. 19–22 (grading, cattle guards), Sept. 3–6 (paving) | The WHMA turnoff off Highway 89, both vehicle and walk-in access |
Two agencies, two purposes, two calendars, sharing one turnoff. The levee crew never blocks you. The paving crew, for four days starting next week, blocks you completely, and those four days happen to swallow the Saturday and Sunday of Labor Day weekend before reopening for the holiday Monday itself.
The Ramp Itself Isn't Going Anywhere
If your weekend plans run through South Park Landing, the distinction matters more than it sounds. The boat ramp is on Bureau of Land Management ground, managed as a public access site by Teton County Parks and Recreation, and on a hot day it's long been counted among the busiest launches on the Snake River, right alongside Sheep Gulch upriver. None of that changes because of the levee work. The area remains open to visitors for the duration of that project, and the county has simply asked people to stay out of the active work zones and give the equipment room.
The paving closure is the one that actually cuts off access, and only for those four days in September. During that window, the county's own guidance points anglers and paddlers to Von Gontard Landing Public Access Area, about six miles south of Jackson on the opposite side of Highway 89 from where Flat Creek meets the Snake. It's not the same put-in, but it's the workaround while the turnoff itself is closed.
The levee crew closes nothing. The paving crew closes everything. Confuse the two and you'll plan a Labor Day weekend float around the wrong set of rules.
The Pathway Is Already Quiet Again
If the noise on Feedground Road has you assuming the pathway is torn up too, it isn't, not anymore. Friends of Pathways and Teton County ran their annual sealcoating maintenance from August 3 through 7, including the stretch of the South Park Loop Pathway between Blair Drive and West Boyles Hill Road. That work is done. The path is back to normal. What you're hearing now on Feedground Road has nothing to do with the bike route that gets kids and commuters into town without crossing a highway.
That distinction matters for the households this stretch of road actually serves. This corner of the valley isn't one subdivision, it's several, each built on a different bet:
- Rafter J, platted starting in 1979, holds roughly 492 residential parcels by the county's own parcel map, with an owner-run HOA maintaining trails and open space and a separate improvement district handling water, sewer, and roads since 1998.
- Melody Ranch, about five miles south of town, was master-planned around giving up density for space, roughly 70 percent of the land held as open ground, with a trout pond and Flat Creek frontage running through it and around 390 parcels on the county map.
- South Park Ranches, tucked into the middle of the loop, carries about 123 parcels on larger, older lots.
None of those households are affected by a levee. Every one of them is affected by whether Feedground Road is passable on a given morning.
What Actually Goes Quiet, and When
Once the paving wraps around September 6, the road returns to a single kind of disruption rather than two. The levee crew keeps working through the end of the month, but that's the project that was never closing the turnoff in the first place, just sharing it. By early October, the heavy equipment clears out entirely and the corridor goes back to ordinary weekday traffic.
It doesn't stay quiet all winter. The South Park Wildlife Habitat Management Area was established in 1939 specifically to keep elk off private land in the winter, and it does that job the same way it always has: roughly a thousand elk fed daily from horse-drawn sleighs, starting in December and running through May. That's a different kind of traffic on the same stretch of road, on a schedule that has nothing to do with either agency working there right now. The Corps finishes its levee. Game and Fish finishes its paving. And a few months later, the road belongs to a feeding operation that predates both projects by more than eighty years.
Three operators, three timelines, one road. The trucks you hear this week aren't the same trucks you heard in August, and neither has anything to do with the sleighs that show up in December. Living along South Park Loop Road means holding all three calendars at once, not collapsing them into a single blur of road work that will supposedly clear up eventually. It clears up in stages, and each stage has its own end date.
If you're weighing a move within this stretch of the valley, or thinking about what a property along Flat Creek or the South Park pathway is actually worth once you understand which disruptions are permanent infrastructure and which are four days in September, Colby Murphy tracks this market at the level of individual roads and closures, not just headline listings.
