The Wildlife Loop Is Clearer During the Buffalo Roundup Than It Is This Week

If you tried to drive the full eighteen miles of Wildlife Loop Road this week and turned back at a barricade, you didn't pick a bad week by accident. You picked one of the exact weeks the road is hardest to finish.

Since mid-August, the South Dakota Game, Fish and Parks Department has been resurfacing Wildlife Loop Road in sections, holding roughly nine of the eighteen miles open at a time while crews work the rest. That means anyone driving the loop this week is doing it in halves: pick a direction, hope the closed stretch isn't the one with the bison herd that day. The project started July 12 and runs into late September, and the sectional closures were built to intensify after August 15.

Here's the part that surprises most people who live here rather than visit: the road goes back to fully open, all eighteen miles, during the single week the park expects its biggest crowd of the year. Construction stops entirely for the week of the Buffalo Roundup, September 20 through 27, with the roundup itself set for Friday, September 25. It also stopped for the ten days of Sturgis Rally, August 6 through 15. So the two weeks a longtime resident might plan to avoid the park altogether, because that's when the out-of-town traffic peaks, are exactly the two weeks the Loop is easiest to drive start to finish. The quieter weeks in between, the ones that feel like a good time to slip out for an evening drive, are when you're most likely to hit a section that's down to one lane or closed outright.

Why the State Scheduled It This Way

This isn't an accident of timing. The park's Division of Parks and Recreation director, Scott Simpson, framed the pauses around protecting "the utmost outdoor experience to visitors when they are here." Read plainly, that means the project is built to inconvenience the calendar's quiet stretches so the loudest weeks stay clean. If you live in Custer and treat the space between events as your window to get out and drive the Loop without a crowd, this year that window has construction in it instead.

The practical math: half the road, roughly nine miles, is what you get on any given day right now. The other half opens back up around September 20, just ahead of the Arts Festival's September 24 start and five days before roundup morning, when gates open at 6:15 a.m. and the herd runs at 9:30.

Two Projects, Not One

Part of the confusion locals run into is that there are two separate road projects layered on top of each other this year, on two different roads, running on two different clocks.

Wildlife Loop Road itself is the resurfacing project described above, the one with the rolling nine-mile openings. It's a Game, Fish and Parks project focused entirely on the loop.

U.S. Highway 16A, the approach road that connects the park to Mount Rushmore and carries most Keystone-side traffic, is a separate South Dakota Department of Transportation project. It included a full two-mile winter closure from January through early April, with a six-mile gravel and two-mile paved detour running through Ritterberger Road, Cobb Road and LH Road at a 25 mph limit. That closure ended April 3. As of the department's July 27 project update, what's left on 16A is sign installation, permanent seeding and cleanup, and SDDOT scheduled no work at all from September 22 through 27 to keep the roundup approach clear. The contract for that project doesn't formally close until October 30, so expect to see equipment and signage along 16A well past the point where the Loop itself is finished, even though the heavy disruption there is largely behind us.

If your daily drive takes you through the park on 16A toward Keystone or Mount Rushmore, you've likely already noticed this project winding down. If your drive is the Loop itself, for an evening wildlife run or a weekend with visiting family, you're dealing with the newer, more active project.

What Stays Open No Matter What

A few things don't change regardless of which half of the Loop is closed on a given day:

• All interior gravel roads inside the park boundary remain accessible through the entire project.
• The Wildlife Station Visitor Center stays open and reachable.
• Wildlife itself, bison, burros, antelope, doesn't relocate for construction. Herds are still visible from whichever half of the Loop is open.
• The Bison Center at the Buffalo Corrals, a stop most locals already know for its interpretive displays and restrooms, sits along the route and isn't affected by the sectional work.

None of that solves the problem of wanting to drive the whole eighteen miles in one pass. But it means a shorter version of your usual route, entering from one side and turning back rather than completing the loop, still gets you the wildlife and the drive, just not the full circuit.

If You're Coming From Town

Custer sits just outside the park on the west side, which means most local trips onto the Loop start near the Blue Bell entrance rather than the east entrance by the park's main visitor center. That's worth knowing because the two entrances aren't interchangeable this month. If the western stretch happens to be the closed half on a given day, backtracking to try the east entrance means driving most of the way around the park's perimeter roads to get there, not a quick U-turn.

The practical habit worth building for the next month: check which section is open before you leave rather than after you're already past the Blue Bell gate. The state's road condition line and the park's own channels post current status, and a five-minute check saves a wasted half hour of driving to a barricade and back.

The Case for Waiting a Few Weeks

None of this is an argument to stay off the Loop until October. It's a case for adjusting expectations depending on which week you're driving in. Right now, through mid-September, plan on half the road and a shorter loop. If you specifically want the full eighteen miles in one continuous drive, whether that's for a proper evening wildlife tour or to show the park to someone visiting for the first time, the week bracketing the Buffalo Roundup is the one time between now and late September when that's guaranteed. The roundup itself draws thousands of spectators into a narrow window on the morning of the 25th, so if crowds bother you more than construction does, aim for the days just before or after rather than roundup morning itself. The Arts Festival runs Thursday through Saturday, September 24 through 26, which gives a few extra days on either side of the main event where the road is open and the crowds are lighter than roundup morning but heavier than a typical Tuesday.

For anyone who's lived here long enough to have a favorite pullout on the Loop, a spot where the light hits right at dusk or where the burros always seem to be waiting, this is the year to hold that plan loosely. The road you know is temporarily a different road, and it's going to stay that way in pieces until the project wraps in late September, with the broader corridor work trailing into fall.

Living in Custer means the park isn't a place you visit once and check off. It's a road you use, a place you take people, a stretch of prairie and pine you drive through on a normal Tuesday without thinking twice about it. This year that habit needs a small adjustment, and now you know exactly which weeks call for it and which weeks don't.

If you're weighing a move to Custer, or already live here and are curious what a property near this stretch of the park is actually worth this season, the team at Black Hills Homes & Land knows this corridor as well as anyone.
