The network’s real geometry — every bridge, every blockSaint Paul, Minnesota — the petition, in one continuous walk
A park,
one story up.
Forty-seven blocks of climate-controlled, publicly owned corridor — the largest system of its kind anywhere. Reclassify it as a linear park. Keep it public. Welcome everyone in.

01 — The premise
Why “linear park” is the right frame — not just a nicer name.
Downtown Saint Paul owns roughly five miles of climate-controlled, second-story, glass-enclosed corridor connecting forty-seven blocks. It was built as commuter plumbing — parking ramp to desk at 8:55 a.m. without touching a January sidewalk. That premise has collapsed.
A linear park is a typology, not a nickname: a continuous public corridor laid over pre-existing linear infrastructure — a rail line, a riverbank, a buried stream — blending recreation with movement. The skyway already qualifies structurally. What it lacks is the programmatic identity of a park. Reclassification is the lever that gets it.
“The skyway is administered by Safety and Inspections — the right office for an elevator code violation, the wrong office for asking what this space should be.”

Parks that were something else first.
Five precedents, a peer next door, and a proof at home. Each began as single-purpose infrastructure; each was reframed as public space by the people already using it. Each compounded.

The Artsgarden.
A skywalk junction, owned by the arts.
Seven stories of glass suspended over Washington & Illinois — a $12M dome funded by the Lilly Endowment, designed by Walter S. Blackburn’s firm (the practice he built with his wife and partner, Alpha) with Ehrenkrantz Eckstut & Kuhn. It joins the skywalks of all four corners, and it is owned and run by the Indy Arts Council: cafe tables by day, concerts and weddings by night. The governance this petition asks for — a corridor node held by a cultural nonprofit — has stood over a Midwest intersection for thirty years.

Subtraction as design — the budget went into what got removed.

The High Line.
The policy bed matters more than the structure.
Two neighbors — writer Joshua David and painter Robert Hammond — met at a 1999 community-board meeting where the viaduct was slated for demolition, and founded Friends of the High Line that night. Joel Sternfeld’s photographs of the self-seeded meadow became their argument; the city rezoned, and the ruin became the most-visited park in New York — ~$2B in adjacent investment. Its failure mode, displacement, is the one to plan against.

The Skywalk.
Don’t wait for the title to act like a park.
Des Moines is reprogramming its skywalk in place — cloud walks, light domes, murals, lantern galleries, a winter mini-golf tournament through the corridor, wayfinding you can actually follow. Not a precedent from another typology: the same corridor DNA, treated as public space today.

The postcard years

Town Square Park.
The most beloved asset the system ever had — and Saint Paul already built it once.
In 1980 Saint Paul opened a real public park inside the skyway grid: trees and terraced gardens under a glass roof, waterfalls, banners, lunch-hour concerts in January — run by Parks & Recreation, at skyway level. Its thousand-panel glass roof failed in 2000 and the park has sat vacant ever since — 24,000 square feet at the busiest junction in the grid, roof still overhead. Town Square proved the park for one block; the linear park brings it to all forty-seven.

It keeps happening anyway.
Nobody schedules a bike race, a 5k, and an art opening in “commuter plumbing.” They scheduled them here.

The roof wins.
Leaking single-pane glazing closes the park. Twenty-five years vacant at the system’s busiest junction — the lesson isn’t that it failed, it’s that nothing replaced it.

04 — What they share
Reinterpretation, not restoration.
None required tearing the structure down. Each took the structure as a given and changed what it was for. A constituency reframed it as public space first — the capital, programming, and political will followed. And Saint Paul has run this experiment before: for two decades, Town Square Park was the proof.
That constituency, here, is us.
05 — The climate case
The weather is changing the assignment.
More extreme days on both ends — heat waves, deep freezes, and wildfire-smoke summers when going outside stops being an option. Cities are now building indoor public refuge on purpose. Saint Paul already owns five miles of it.
The hot days are coming north.
At current emissions, the 100°F-heat-index day — temperature plus humidity — spreads up the map decade by decade, reaching Minnesota with real frequency by mid-century. New York is standing up cooling shelters now. Saint Paul already has one: cooled, filtered, five miles long, connected to housing, transit, clinics, and groceries.
And the same corridor answers the other extremes — the −30°F mornings we’ve always had, and the smoke summers we now get, when air-quality alerts make outdoor exertion a risk for kids, seniors, and anyone with lungs that complain.
Heat, cold, or smoke — the answer is already built.
The refuge ledger
Refuge from every extreme, already built.
Extreme days are rising on both ends of the thermometer, and the smoke years land on top of them. Every outdoor park downtown closes with the weather; the skyway is the one that doesn’t have to — warm in January, cooled in July, filtered when the AQI spikes.
That makes the corridor climate infrastructure, not an amenity: level, salted-sidewalk-free walking for seniors, strollers, and wheelchairs, every single day. Town Square Park proved a garden winters here. A linear park scales that refuge to the whole grid.
Outdoor parks close when the weather turns. This one opens.

“Downtown solutions need to be ‘and’ not ‘or’ when it comes to skyway vs. street level — both are really important.”
Worker — 51–70 — uses it a few times a month
07 — The application, Saint Paul, 2026
The skyway, read correctly.
“Linear park” is a more accurate description of the thing than “skyway system” — and a park is the only program that uses the asset at its potential.
01
Office of record
From Safety & Inspections into the orbit of Parks & Recreation — the office built to program space, permit events, run art commissions, partner with conservancies.
02
Conservancy partner
The Alliance is that conservancy — the Friends-of-the-High-Line relationship, standing ready the day the city names the park.
03
Capital planning
From “what does it cost to keep the lights on?” to “what does the corridor want to be?” Surfaces, lighting, plantings, events — not a signature object.
04
Governance & hours
City-owned bridges pass through private buildings that control hours. A closed connection reads differently when it is a public park — no owner can close the sidewalk out front.
05
Displacement, owned
The High Line’s failure was wealth displacing poverty; the skyway’s risk is closing the asset against the people already using it. Own that at the front end — in the founding documents.
08 — Into the grid
A park is only public if you can get in.
Keeping the skyway public means stitching it back into the downtown grid: street doors you can find, hours you can trust, transit at the threshold, and directions anyone can use — skyway and street level, never one against the other.
The tools already exist. Both frames on this wall are live services from spskyway.com — the same embeds any Alliance partner site can carry.

09 — The Alliance
We see the network for what it could be.
We are residents and business owners pursuing the practical vitality of downtown — encouraging investment in places and in people. We organize support and raise funds for small projects throughout the system that accumulate into substantial change. When the city names the park, the Alliance is its conservancy — the partner that programs, fundraises, and keeps asking.
Reclassify
As a linear park — formally, administratively, in the capital plan.
Keep it public
The ownership is the lever. Never trade it away.
Welcome everyone
A park is for its whole city — programmed for the people already here.
Small projects compound — the corridor already collects art
Wayfinding, lighting, a bench, a mural, a pop-up permit — none of it needs a ribbon-cutting. It needs a category that lets it happen, and a constituency that keeps asking.
