§ I · 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 — a way to get an office worker from a parking ramp to a desk at 8:55 a.m. without touching a January sidewalk. That premise has collapsed. Post‑pandemic office occupancy hollowed out the foot traffic the skyway was designed to channel, and the spaces are now read by users and the press as “unsafe, unsanitary, and uncomfortable,” which is what happens to any piece of infrastructure when the only use case it was optimized for goes away.
The argument here is that the skyway should be reclassified — administratively, rhetorically, and in capital‑planning terms — from circulation infrastructure to linear park. That move has prior art. Five projects illustrate five different routes to the same destination: the SkyMart in Morristown, Tennessee; the San Antonio and Tampa Riverwalks; the Cheonggyecheon stream restoration in Seoul; and the High Line in New York. They differ in scale, geography, and aesthetics, but they answer a common question: what do you do with a piece of single‑purpose civic infrastructure once its purpose has expired?
A linear park is a typology, not a synonym for “park that is long.” In urban‑planning usage it is a continuous public corridor whose form follows a piece of pre‑existing linear infrastructure — a former rail line, a riverbank, a buried stream, a utility easement — and whose function blends recreation with movement. The walker is going somewhere. That is what distinguishes a linear park from a plaza, a green, or a square.
The Saint Paul skyway already satisfies the structural requirements. It is continuous, publicly owned (unusual — Minneapolis’s larger 9.5‑mile system is privately owned), enclosed, and connects the entire downtown street grid at the second story. What it lacks is the programmatic identity of a park: maintenance budget, a unifying design language, curated public space, a permit framework for events and vendors, a constituency that thinks of itself as park users rather than commuters in transit. Reclassification is the lever that gets those things.
§ II · the five precedents
Five linear parks. Five economic arcs.
Each was a piece of obsolete single-purpose infrastructure. Each got reframed as public space. Each compounded. Scroll through the five — click any to read its case in full.
§ V · what the five share
Reinterpretation, not restoration.
The five precedents share one structural move: each was a piece of single‑purpose infrastructure whose original program had expired, reframed as public space by a constituency that was already using it. See the side‑by‑side at the precedents page.
A piece of single‑purpose infrastructure outlives its purpose. There is a window of years to decades during which the structure reads as a failure, an embarrassment, or a liability — costly to maintain, awkwardly sited, hard to demolish. The successful cases all involve a constituency that reframes the structure as public space first and then attracts the capital, programming, and political will to follow through. None required tearing the original structure down. None is, strictly, a restoration: each is a reinterpretation that takes the structure as a given and changes what the structure is for.
§ VI · the application
Saint Paul, Minnesota
The skyway, read correctly.
The case from outside is one half; the demand from inside is the other. Saint Paul’s own constituency — 681 of them, on the record — has already asked for what the precedents prove (see the demand). The rest of this section is the application.
The skyway today is the largest publicly owned enclosed pedestrian system in the world, at roughly five miles across forty‑seven blocks. That public ownership is the lever.
Saint Paul
5 mi
47 blocks · publicly owned· the lever
Minneapolis
9.5 mi
Longer — but privately owned. No public lever, no public mandate.
Riyadh · KAFD
9.61 mi
Longest in absolute terms (2025). Privately operated — a business district, not a city.
What reclassification would change, concretely:
Office of record
Moves from Safety and Inspections— the right office for an elevator code violation, the wrong office for asking what this space should be — into the orbit of Parks and Recreation. Parks departments are designed to program space, recruit volunteers, write event permits, run public art commissions, partner with conservancies.
Conservancy partner
skywayfriends.org becomes the natural conservancy partner — the same structural relationship Friends of the High Line has with the New York City Department of Parks and Recreation. That model now has a national network behind it.
Capital planning
Shifts from “what does it cost to keep the lights on?” to “what does the corridor want to be?” Cheonggyecheon’s precedent: spend on surfaces, lighting, water, plantings, and event infrastructure, not on a signature object.
Governance & hours
The bridges are city‑owned but pass through privately‑owned buildings whose owners control hours and access. Building owners closing connections reads very differently when the connection is a public park — the way a building owner cannot unilaterally close the sidewalk in front of their property. A real legal‑instrument question that reclassification forces into the open.
Displacement, owned
The High Line’s failure mode was wealth displacing poverty; the skyway’s risk is the opposite — closing the asset to avoid programming for the people who already use it. The honest answer is to own this at the front end, the way Morristown did when it decided the SkyMart was for the town’s own people, not for an imagined returning customer base.
