If you ride, walk, or run the Rillito stretch of the Loop on any kind of schedule, you already know the rhythm of this trail better than any guide can tell you. You know where the shade runs out by 9 a.m. in September and where the mesquites still hold it. You know which underpass floods first when the wash actually runs. What you might not know, because the changes this year didn't arrive as one clean update, is that three separate things you'd have reasonable cause to assume about this corridor are no longer true. A bridge that got a ribbon-cutting in May wasn't actually driveable until a month later. A racetrack that usually fills its grandstand every February sat empty for a third straight season. And a stretch of path that used to be defined by horse racing is now, more accurately, defined by a coffee shop and a mural.
None of this is a story about the Loop getting bigger. It's a story about a piece of infrastructure that looks stable on the surface while quietly changing underneath it. Here's what's actually true along the Rillito this fall.
The bridge that opened twice, sort of
The Sunset Links project, the $171 million effort to finally connect River Road to Interstate 10 and Silverbell Road on the northwest side, held its ribbon-cutting ceremony on May 6, 2026. Pima County Board Chair Jen Allen, Tucson Mayor Regina Romero, Oro Valley Mayor Joe Winfield, and RTA Board Chair Tom Murphy were all there. Cameras rolled. Officials called it a critical missing connection, finally resolved after nearly three years of construction on bridges over the Rillito River and the Union Pacific rail lines.
There was one problem. The traffic signals weren't wired yet. Motorists still couldn't use the road. The bridge that got a ceremony in May didn't actually open to traffic, or to the cyclists and walkers using the new Loop access path built into it, until June 10, 2026, more than a month later.
That gap matters if you're the kind of Loop user who plans routes around what you read in a headline rather than what you can confirm on the ground. This isn't the first time this exact intersection has done this to people. A local columnist tracked the fuller history back to 1983, when the original one-lane Bailey bridge over the Santa Cruz River washed out in a flood. A partial replacement opened in February 2017, giving northwest side residents a working Sunset Road connection for the first time in over three decades. That version lasted six years before it was closed again in 2023 for the I-10 widening that produced the bridge open today.
So the pattern here isn't new construction, then done. It's open, closed, half-open, actually open. If you're routing a ride toward River Road and I-10 this fall, the good news is the connection is real now and it includes a dedicated access path into the Loop from Sunset Road itself, meaning you can cross under the road instead of over it for the first time. The caution is that a ribbon-cutting on this stretch has historically meant "soon," not "now."
The racetrack that stayed quiet for a third year
If you've lived near Rillito Park long enough, you probably assume the grandstand fills up every February and empties out by early April, the way it has for most of the last eight decades. Rillito Park Race Track was established in 1943 and holds a real claim to history: it's credited as the birthplace of modern Quarter Horse racing, and Bob Baffert notched his first win as a thoroughbred trainer there in 1979.
That assumption didn't hold this year. Pima County confirmed in advance that the 2026 season was, in the county's own words, "most likely not achievable," after a request for proposals issued in March 2025 drew no operator bids. The county had already put improvements to the grandstand and clubhouse on hold, having spent roughly $40,000 on a required emergency warning system before pausing further work. That made 2026 the third consecutive year without a single race at Rillito.
What comes next is still unsettled, but the direction is worth knowing if the track is part of your regular walk. County officials and members of the Parks and Recreation Commission have floated moving racing to a new facility near the Pima County Fairgrounds or in Marana, and using the freed-up space at Rillito Regional Park to expand youth soccer fields for FC Tucson. One commission member has pointed out that a third of the property sits unused for roughly nine months of the year outside racing season, an argument for the soccer expansion regardless of where racing eventually lands. Nothing here is finalized, but if you've been wondering why the track feels dormant this fall, that's why, and it's not a one-season pause.
What's actually filling that stretch of trail now
Walk or ride past Rillito Park today and the activity you'll notice isn't horses. It's art and coffee.
The Rillito section carries the densest concentration of public art anywhere on the Loop, more than three dozen pieces along a system that has more than 130 miles to work with. Two are worth detouring for on purpose:
- Tracks and Trails, a 4,000-square-foot mural along the retaining walls on the river's north bank, completed in 2023 by artists Jessica Gonzales and Rock "CYFI" Martinez. It's the largest single mural in Pima County's public art collection, and it was built specifically to draw people in as they move down the trail rather than as a static backdrop.
- A metal sculpture of a bat family on the south bank at the Campbell Avenue Bridge, marking the spot where thousands of Mexican free-tailed bats roost through the summer months, drawing crowds of evening bat watchers.
For a break, Ren Coffeehouse sits directly on the trail inside St. Philip's Plaza at Campbell and River, close enough to the path that it functions as a de facto rest stop for riders. It sources coffee from two local roasters, Yellow Brick Coffee and Presta Coffee, gets its bagels from Bubbe's across the road, and pulls milk from Tirrito Farms. It's a small business built entirely on other small businesses along this same stretch of river, which is a fair summary of what this section of the Loop has become since the track went quiet.
Two dates worth putting on the calendar
Two organized rides are using this same stretch of trail this fall, and both are worth knowing about whether or not you plan to ride in them, because they'll change how crowded and how loud the path feels on those mornings.
Loop de Loop happens Saturday, September 26, 2026, starting at 7 a.m. at Rillito Park Race Track, with riders free to join anywhere along the Loop and go as far as 10 to 20 miles or attempt the full circuit. It wraps by noon with an after-party and live music back at the racetrack starting at 10 a.m. It exists as a warmup for the bigger event on the calendar, El Tour de Tucson, set for November 21, 2026, with routes ranging from a flat 1-mile family ride to a 102-mile century that pushes out past Davis-Monthan Air Force Base toward Colossal Cave and through Vail, Sahuarita, and Green Valley before finishing back at the Tucson Convention Center.
If your normal routine has you on the Rillito path on either of those two Saturdays, expect company. If you'd rather have the trail to yourself, this is useful information for picking a different weekend.
The takeaway for anyone who already lives here
Nothing above changes what the Loop is. It's still the same paved system that connects the Rillito, Santa Cruz, and Pantano river parks, still free to use, still one of the more reliable ways to get somewhere in this city without a car. What changed is what you can assume about any single piece of it holding still. A connection that looked finished in May wasn't. A season that always happens didn't. A landmark built for horses is currently better known for its coffee.
That's a useful thing to know if you're the kind of person who plans a Saturday around this trail, and it's the kind of granular, ground-level shift that only shows up if you're paying attention to this specific half mile of river rather than the city as a whole.
Marta Harvey has spent two decades paying attention to exactly this kind of detail across Tucson's foothills and river corridors, the changes that don't make the evening news but shape how a neighborhood actually lives day to day.
