Nobody planned for the Bee Branch Creek Greenway to become the place where half the North End walks its dog after dinner. The one-mile stretch of open water and pavement running from the heart of the North End to the Mississippi River at Chaplain Schmitt Island was engineered to survive a storm most residents will never see in their lifetime, one dropping 5.6 inches of rain in two hours, the kind of event statisticians call a 500-year storm. That's the job the creek was built to do. The fact that it also turned into Dubuque's most-used everyday trail is closer to an accident than a design goal, and the accident got a lot more interesting in 2022 when a pair of pedestrian tunnels quietly stitched it into something much bigger.
What the Creek Was Actually Built to Do
Before the greenway existed, this stretch of the city ran on an underground storm sewer that couldn't keep up. Longtime civil engineer Deron Muehring, who worked the project from the start, has described street flooding that put three and a half to four feet of water in the road, floating cars and stranding drivers. The Bee Branch Watershed Flood Mitigation Project, a multi-phase effort now running more than two decades, was the city's answer. Converting the old underground sewer into an open-air channel meant the water finally had somewhere to go besides someone's basement, and the project is projected to prevent an estimated $582 million in damage over its 100-year design life while protecting more than 1,300 homes and businesses.
The Upper Bee Branch Creek Greenway itself, the visible, walkable centerpiece, opened to the public on July 19, 2017. It's a 1,938-foot corridor with a trail system that totals 1.56 miles across two overlapping loops of 0.82 miles each, paved in asphalt and concrete. The lower loop, the one that hugs the creek most closely, floods on purpose during heavy rain. That's not a maintenance oversight, it's the design working as intended, moving water off the streets and into a channel built to hold it. The upper loop, which links to the Heritage Trail, is graded to stay dry. If you've ever wondered why one section of pavement occasionally shows up soaked while the other never does, that's the answer.
"Anything that happens to that watershed affects a lot of people," Muehring has said.
The Tunnel That Actually Connected Everything
For its first five years, the greenway functioned as an island. It was a genuinely pleasant one, but it dead-ended at the Canadian Pacific Railway tracks near Garfield Avenue, cut off from the Heritage Trail system that ran alongside it. That changed on June 24, 2022, when the city opened a set of pedestrian tunnels underneath the rail line, linking the upstream and downstream trail networks for the first time. The result is a single continuous off-street route running from the Heritage Trail in Dyersville all the way to the Mississippi River in downtown Dubuque, something that simply didn't exist as one connected path before that Friday.
If you live near the corridor and haven't walked it end to end, here's what the connected route actually looks like today, heading west from the river:
- From Chaplain Schmitt Island, the trail runs about a mile west along the Bee Branch corridor through the greenway itself, passing the amphitheater, community orchard, and playground before the underpass at Garfield Avenue.
- Around 2.4 miles out, the route meets the NW Arterial Bike/Hike Trail, a second connection point most people driving the arterial every day have no idea sits just off the shoulder.
- By 3.6 miles, you reach Heritage Pond in Sageville, where the pavement ends. From there, the surface switches to crushed limestone for the rest of the roughly 30 miles to Dyersville, threading through a valley that drops 450 feet and past old mining and mill towns along the way.
That last stretch isn't a manicured city park anymore. It's a rural rail-trail, and the tunnel is the only reason a Dubuque resident can start at the riverfront and end up in farm country without ever crossing a road at grade.
The Small Things Along the Way
Walk the greenway itself and you'll pass a stone slab fountain near the 22nd Street bridge that feeds directly into the creek, and the corridor offers free public WiFi for anyone who wants to check a map or answer an email mid-walk. In July 2017, the city installed 14 floating islands in the creek between 16th Street and the Highway 151/61 overpass, part of an effort to establish a working ecosystem in what had been a buried sewer a year earlier. It worked well enough that the Iowa DNR later documented 14 native fish species living in the creek, including bluegill, largemouth bass, and northern pike alongside common carp, a healthy population for a waterway that young.
The city also ran a donor campaign starting in 2018 that let residents put their names on pieces of the greenway, from $500 trees and $1,000 bike rest stations up to $25,000 bridge sponsorships and a $50,000 donation that named the play area with slides. If you've ever noticed a small plaque on a bench along the trail, that's why it's there. Someone in the neighborhood paid for it.
Parking is scattered enough that it's worth knowing before you go. For the greenway itself, there's a lot at the corner of East 22nd and Prince, plus access near Comiskey Park at 255 East 24th Street. For the eastern end of the Bee Branch Trail, Pyatigorsk Park off Kerper Boulevard is the spot, easily reached from either direction of Highway 61/151. And Chaplain Schmitt Island itself carries its own piece of local history: it's named for Aloysius Schmitt, a Dubuque priest who became the first U.S. Navy chaplain to die in World War II after helping a dozen sailors escape the capsized USS Oklahoma during the attack on Pearl Harbor.
What This Actually Means If You Live Nearby
The practical takeaway isn't complicated, but it is easy to miss if you've only ever thought of the greenway as your block's park. If your daily walk starts anywhere near the North End, you're not limited to the mile of trail closest to your door. You can head east and be at the Mississippi River in under a mile, or west and eventually find yourself on crushed limestone headed toward Dyersville, a route that didn't exist as a single unbroken path until a tunnel opened under a rail line four years ago. The creek was never supposed to be a trail. It just turned out to be a good one, and the 2022 connection made it a much longer good one than most residents have gotten around to noticing.
