Catalina State Park Spends Its Last Winter Behind a Ford That Sand Can Close

About 2,000 feet past the entrance station at 11570 N. Oracle Road, the main road into Catalina State Park drops into the Cañada del Oro Wash and crosses it on a concrete ford roughly 200 feet long. On a dry morning most drivers barely notice it. Still, that low strip of concrete is the only road link between the park's front door and nearly every reason to come.

Work to replace it started the week of October 19, 2026, and Arizona State Parks expects to finish in May 2027. That puts the whole project inside the park's prime season. It also makes this season the last one in which a morning on the Romero Canyon Trail depends on what the wash did overnight.

What Sits on the Far Side

The visitor center and ranger station are at the entrance, on the near bank. Almost everything else is past the ford:

• The main trailhead, with its parking lot, picnic tables and the Trailhead Stage
• Romero Canyon Trail and Sutherland Trail, which both start there, and the Canyon Loop
• Romero Ruins, its ramada parking and interpretive trail
• The equestrian center, the park's staging area for riders with horse trailers
• The campgrounds, including 120 electric and water sites open year-round, plus Ringtail camping from January 1 through March 31

Spread across about 5,500 acres of foothills and canyons that hold nearly 5,000 saguaros, the park feels open in every direction. Its road network still runs through one point. When the ford can't be crossed, the park splits in two, and the part people come for is on the other side.

Sand, Not Water, Closes the Road

In mid-January 2023, a rainy weekend sent water through the Cañada del Oro, and the park closed beginning Monday, January 16. ABC15 reported that roughly 200 to 300 campers couldn't drive out. KGUN reported that by January 18 the problem had shifted from the water to what it left behind. Park manager Steven Haas told the station:

"It's not the water that stops people it's the sand so we are in the process of trying to remove all that sand. And there's about 5 feet of sand just sitting in the road."

In the same KGUN report, Haas said flooding like this is common in summer, when the campground is in its off season, and less common in winter, when the sites are full. He also said State Parks had funding for a bridge and was working with ADOT, and he called it probably a two- or three-year project. Construction began a little more than three and a half years after that closure.

The park's facility page still warns that runoff and debris since the Bighorn Fire can be hazardous, and that flash flooding near the campground can keep campers from leaving until the water goes down. In 2023 the water passed, and the sand it left on the ford kept the road closed for days.

What Replaces the Ford

The permit describes an all-weather crossing. It's a box culvert 183 feet long with seven cells, each 26 feet wide and 7 feet tall, set into the wash so floodwater runs underneath. The road deck on top carries:

1. One 12-foot travel lane in each direction
2. Six-foot paved shoulders on both sides for non-motorized traffic
3. Curb and bridge railing barriers along both edges
4. Pedestrian paths on both sides of the crossing

The Arizona State Transportation Board's award record calls the same structure a reinforced concrete slab bridge built as a seven-span, cast-in-place closed frame. Both descriptions agree on the result: traffic will cross above the channel instead of on its floor.

The permit also shows that most of the project goes after the sand problem. Crews will clear a sand and debris island that restricts flow and grade the channel from bank to bank. They will then reuse the excavated material for berms upstream and downstream that keep the Cañada del Oro in its main channel. Riprap armoring and gabion walls will protect the banks. A lean-concrete scour floor 182 feet long will go in on the downstream side. A concrete swale on Drive D, also called Equestrian Road, will let water cross that road without damaging the pavement.

Riders and walkers who use the road between the trailhead and the campground loops get a lasting change too. They will have shoulders and dedicated paths across a stretch that is now shared pavement at the bottom of a wash.

Why the Wait Ran Through 2026

The bridge Haas mentioned in 2023 took a while to reach a contractor. The Transportation Board agenda lists it as 100 percent state funded, and ADOT project records tie it to HB 2858, Section 6, with a $5.813 million appropriation. An earlier cost estimate came in above that appropriation, which pushed construction from fiscal year 2025 to fiscal year 2026. A permit attachment once projected work starting in early fall 2025 and wrapping up by late spring 2026. In the end, the whole schedule moved back a year.

When bids finally opened, they came in well under expectations. Six contractors bid. The department's estimate was $5,211,036, and Hunter Contracting Company's low bid was $3,175,119.20. The Transportation Board awarded Hunter the contract on September 18, 2026. A project that stalled because it cost too much ended up being awarded for about 61 percent of the state's own estimate. The tradeoff is timing, since the work runs straight through hiking and camping season.

How the Park Works Until May

State Parks says park activities will continue, with construction vehicles, noise and workers on the main road. KVOA reported that day use and camping will go on without interruption, with posted detours where the road crosses the wash.

The permit explains the detour. Crews are building about 1,000 feet of temporary road next to the new scour floor, downstream from the existing ford, with temporary concrete barrier along its north side. Traffic moves onto that bypass during construction, and the permit says no other detours will occur. The bypass comes out once the crossing is finished. Advance signs may go up as far as two miles on either side of the project limits.

So the route to the trailhead still runs through the wash this winter, on a temporary road, while crews work beside it. The fall and winter programs past the crossing are still on the calendar:

The Trailhead Stage is at the end of the park road, 1.5 miles north of the ranger station. Getting to either concert means crossing the work zone. State Parks hasn't announced any parking changes or recommended visiting times for the construction period. Its notice asks visitors to watch for updates as work goes on. The event listings and the park's main page are the places to check before a Saturday trip, and the reservations line is (877) 697-2757 for anyone with a campsite booked into the winter.

If the work stays on schedule, the spring wildflower season will be the first one with a raised crossing over the Cañada del Oro, and the winter ahead will be the last with the concrete ford on the park's main road.

At Saguaro Ranch, a few miles north in the Tortolita Mountains, we watch the washes run and the roads that cross them as closely as our neighbors do.
