Most weeknights from May through September, you can spot the same pattern at the Ankeny trailhead. Someone rolls a bike out of the Firetrucker Brewery lot around 7, checks the time against the sunset, and pedals north with just enough daylight to make the bridge before dark. They know the ritual: ride out while the sky still holds color, stand on the trestle as the blue LEDs click on, ride home under lights. It works because the bridge cooperates. Right now, in mid-August, it stays lit until midnight.
That cooperation has an expiration date, and it isn't tied to the weather the way most people assume.
The switch nobody mentions
Ask anyone in Ankeny when the good riding season ends and they'll say something about frost or shorter days. Fair enough, but the detail that actually reshapes your evening ride schedule is a lighting policy, not a temperature. From April through October, the High Trestle Trail Bridge stays lit from sunset until midnight. Starting in November, that same lighting cuts off at 9 p.m.
Stack that against what's already happening to daylight in central Iowa this time of year, and the math gets interesting. In August, sunset lands around 8 p.m., which leaves hours of lit bridge to work with after dinner. By early November, sunset has crept back to roughly 5:30, and the lights themselves now shut off at 9. You're not just losing daylight. You're losing the buffer that used to make a casual, no-rush evening ride possible.
Put plainly: the next several weeks are the only stretch of the year where you can leave after work, ride out under real daylight, catch full fall color on the trees along the Des Moines River valley, and still have a wide window to watch the bridge light up before turning around. Wait until Halloween passes and you're threading a much smaller needle, racing a 9 p.m. cutoff on top of an already early sunset.
Ankeny's side of the trail just got a new reason to detour
There's a second reason this particular fall is worth treating differently than the last few. Ankeny has been quietly building out the High Trestle Trail Experience Park, the 14-acre stretch that runs along both sides of the trail near West First Street. Phase one added a 425-foot glow-in-the-dark path, an offshoot that lights up underfoot after dark, tucked just off the main trail.
The next phase is a roughly 900-foot paved flowline trail, a series of small rolling hills built into an otherwise flat rail-trail system, positioned just east of Walnut Street. It's designed to be usable by families pushing strollers, wheelchair users, and kids on bikes, not just serious cyclists looking for a challenge. City officials had it slated to open by the end of this summer, which means this is the first fall it's actually part of the route rather than a rendering on a city webpage. A future phase adds an interactive LED light installation at the underpass beneath South Ankeny Boulevard, so the corridor keeps layering in reasons to linger near the trailhead instead of just passing through it.
None of this shows up if you only ride the trail the way you always have, straight out and straight back. Looping through adds only a few minutes, and it's a genuinely new stretch of pavement to add to a route you've probably ridden dozens of times.
The mile markers that make the trip worth planning around
The 25 miles between Ankeny and Woodward pass through five towns, and each one has become a known stop for a reason. Here's the rundown locals actually use when deciding how far to go and when to turn around.
| Distance from Ankeny | Stop | What's there |
|---|---|---|
| 0 miles | Ankeny trailhead / AMP | Firetrucker Brewery and Trailside Tap sit right at the trailhead, with more than 100 parking spots at the Ankeny Market & Pavilion across the street |
| ~7 miles | The Oasis | A trailside gazebo with picnic tables, water, and restrooms, roughly halfway to Slater |
| Roughly the halfway point | Slater | Nite Hawk Bar & Grill, with trailside bike parking and a repair station |
| ~20 miles | Madrid | Flat Tire Lounge, with an 800-square-foot deck 12 feet off the trail, plus The Filling Station for ice cream and Dave's Back Alley Bikes for repairs or rentals |
| ~22 miles | High Trestle Bridge | The half-mile, 13-story crossing over the Des Moines River, sitting 2.6 miles west of Madrid, with six overlooks and the lit steel ribs after dark |
| 25 miles | Woodward | Whistlin' Donkey, the trail's endpoint, with a full grill menu and live music on many summer weekends |
You don't have to ride all 25 miles to make the trip worthwhile. Plenty of regulars treat Slater as the natural out-and-back point for a weeknight ride, saving Madrid and the bridge for a weekend when there's more daylight to work with.
Timing a ride before the switch flips
If you want to actually use the next few weeks the way they're built to be used, a little planning helps more than luck does.
- Pick an evening before Halloween if seeing the bridge lit is the point. Once November arrives, the lights cut off at 9, and sunset has already moved up by more than two hours since August.
- Start from Firetrucker Brewery or Trailside Tap with at least two hours of daylight left if you're riding all the way to the bridge and back. It's roughly 22 miles each way, and you want margin, not a sprint against the clock.
- Route through the new flowline trail near Walnut Street before you head out. It adds only a few minutes and it's the first season it's actually open.
- If you're only doing a shorter loop, riding out to Slater and back is a comfortable evening distance that still gets you to a real destination, Nite Hawk, before turning around.
- Once the calendar flips to November, shift your riding earlier in the day. The window for a golden-hour ride into a lit bridge basically disappears until the schedule resets again in April.
Why this keeps mattering
The city hasn't treated the High Trestle Trail corridor as finished business. A $10,000 Community Betterment Grant from the Polk County Board of Supervisors went toward benches for the Experience Park, and this year's flowline phase alone carries a price tag around $300,000. That's not the behavior of a city that sees the trail as a nice-to-have. It's the behavior of a city that keeps investing in the same half-mile stretch because people keep showing up to use it.
For anyone who already calls Ankeny home, that's the actual takeaway. The trail isn't static, and neither is the calendar governing it. The next six or seven weeks are the last stretch where daylight, fall color, and a midnight-lit bridge line up in the same ride. After that, you're working around a much shorter window until spring brings the schedule back.
If you're already planning your next ride, you might as well plan it well.
Ankeny's mix of trail investment, walkable neighborhoods, and steady community growth is part of what makes this such a good place to put down roots, and it's the kind of local detail I like sharing with people thinking about their next move here.
