Run the Katy Trail south to its end at American Airlines Center on a Saturday morning this month and you'll notice something that wasn't there a year ago: options. For two decades, hitting that southern trailhead meant one thing. Turn around. Run back the way you came, or peel off onto city streets and hope for the best. That's changing, and the reason has nothing to do with the trail itself getting longer.
The Katy Trail is not getting more mileage this year. What it's getting is a way out.
A Trail That Stopped Growing and Kept Filling Up
The Katy Trail has been 3.5 miles long for years now, a paved and soft-surface greenbelt built on the old Missouri-Kansas-Texas rail line, running from the edge of downtown at American Airlines Center up through Oak Lawn and Uptown to Airline Road near Highland Park and SMU. The Thomsen Overlook plaza above Reverchon Park, one of the trail's signature features, wrapped up construction back in 2007, and even now a short stretch of the secondary soft-surface jogging path is still waiting on funding to finish. The core spine of the trail simply hasn't grown.
What has grown is the crowd on it. More than 300,000 people live or work within a mile of the Katy Trail, and it now records more than 3 million visits in a single year, more than any other trail in the city. Those two numbers together tell you something the trail's flat mileage doesn't: the demand has kept climbing on a footprint that stopped expanding. Every runner, cyclist, and dog walker on the Katy Trail is sharing the same 3.5 miles that existed when property values along it were a fraction of what they are today.
That's the tension the trail has been sitting in. And it's why the real story this year isn't happening on the trail. It's happening next to it.
The Hi Line Connector Doesn't Touch the Katy Trail at All
The new Hi Line Connector is a one-mile urban trail that picks up where the Katy Trail's southern end leaves off, running through Victory Park and the Design District before tying into the Trinity Strand Trail and down into the Trinity River levees. It passes under I-35E and the active DART and TRE rail lines, with a new 12-foot-wide path built wide enough for walking, running, and biking at the same time, plus upgraded lighting and pedestrian signals along the stretch.
Notice what that route does. It doesn't widen the Katy Trail. It doesn't add distance to the 3.5 miles between American Airlines Center and Airline Road. Instead, it gives the crowd standing at that southern trailhead somewhere new to go, out toward the Design District and Victory Park, rather than forcing everyone to double back through the same congested half-mile near Reverchon Park. A companion project, the Loop Plaza, is planned to formally link the Katy Trail to this new connector, stitching the two together as one continuous system instead of two trails that happen to end near each other.
If you've felt like the south end of the Katy Trail is more crowded than it used to be, this is the explanation and the fix arriving at the same time. The trail isn't being widened to handle its own popularity. It's being given an exit.
The Trail Runs on Donations, Not Tax Dollars
Here's the part that surprised me when I looked into who actually pays for any of this. The Katy Trail is a City of Dallas park, but its maintenance and expansion are largely funded by a private nonprofit, Friends of the Katy Trail, through memberships, corporate sponsorships, and annual campaigns. The group's Spring 2026 fundraising push brought in a record $170,000 in operations funding for just the first half of the year.
That structure matters if you've ever wondered why the Katy Trail feels more polished than some of the other trails in the Loop Dallas system, or why it gets new lighting and signage faster than a typical city park might. It isn't riding a municipal budget cycle. It's riding donor enthusiasm, and donor enthusiasm has been high enough this year to set a record.
The clearest proof of that enthusiasm shows up every September at the Katy 5K.
What the Katy 5K Actually Closes Down
If you live within a few blocks of the trail, mark your calendar for Thursday, September 10, from 7:30 to 10 p.m. That's the 28th Annual Katy 5K, presented by Michelob Ultra, starting and ending at Reverchon Park. The course runs through Turtle Creek, Uptown, and the length of the Katy Trail itself, which means the trail's busiest corridor will be closed to normal foot and bike traffic for the evening.
A few things worth knowing if you're planning around it:
- The race finishes into the Katy Picnic Party at Reverchon Park, with food from more than 35 local restaurants and live music, so expect crowds and parking pressure near the park well past the 10 p.m. end time.
- Registrations directly fund Friends of the Katy Trail, so the traffic disruption that night is the same fundraising mechanism keeping the trail's lighting and paving current the rest of the year.
- If your usual route uses the trail's southern half in the evening, plan an alternate loop that night. The Hi Line Connector, still new enough that most regulars haven't built it into their routine, is one option once it ties into the trail near the AAC end.
The Small Signs of Investment Along the Path
Money doesn't only show up in big projects. It shows up in the small stuff too, and the trail has picked up a few new landmarks this year that are easy to miss if you're not looking for them. A new marker at the Harvard Avenue crossing now honors the legacy of Dallas Cowboys great Roger Staubach, and Pegasus Bank has plans for a new location at the intersection of Harvard Avenue and Tracy Street, right along the trail corridor. Neither of those is a large infrastructure project. Both are signs that businesses and civic groups still see the trail frontage as worth building on, even without a single new mile of pavement.
That's consistent with what regulars already know informally. The trail has its own quiet wayfinding culture that has nothing to do with official signage: the ramp down from Thomsen Overlook to Reverchon Park if you need a restroom on the south end, Berkley's M.K.T. at the Knox Street crossing if you need water or a snack on the north end, the Katy Trail Ice House if you're finishing a run and want to sit outside with something cold. None of that is on a map. It's the kind of local knowledge you only pick up by using the trail often enough to need it.
The Real Shift This Year
Put it together and the pattern is consistent. The Katy Trail isn't getting longer, and it probably isn't going to. What's changing is everything around it: a new connector that redirects crowd pressure instead of adding pavement, a private funding model that just posted a record half-year, small honorary markers and bank branches signaling continued investment, and a race that turns one Thursday night a year into the trail's biggest fundraiser. None of that required adding a single foot to the 3.5 miles that have defined the trail for two decades.
If you're the kind of person who already plans your week around a Katy Trail loop, that's worth knowing before September 10 rolls around. And if a friend or family member ever mentions they're thinking about a move to a neighborhood built around this kind of daily life, from Uptown out through Collin County's golf-course and master-planned communities, the team at The Deann Abbott Group spends its days in exactly that kind of local detail.
