Ford Twin Cities Assembly closed in 2011 after building Rangers and Model Ts; demolition crushed 150,000 tons of concrete for backfill and grading on the St. Paul site

Under a new shiny grocery store in St. Paul, Minnesota, there are 150,000 tons of crushed concrete holding up the ground upon which you stand. This concrete can be seen as a former Ford factory. Prior to that, it constructed the Model T, and before that, it was simply a bluff on the riverbank with a Mississippi view. It's now under row houses, a Lunds & Byerlys, and a group of renters who may be oblivious to the fact that they are walking on the bones of American manufacturing.

The plant that built America's road trip, then quietly closed

Ford Twin Cities Assembly Plant began production of Model Ts in 1925 and operated for 86 years on the same Highland Park bluff overlooking the Mississippi. In that time it never built just one vehicle for eight and a half decades, the plant moved through dozens of different Ford models, including the Model T, the Model A, and a long run of postwar cars and trucks, before converting to all-truck production in 1978 and eventually settling into building the compact Ranger pickup in its final decades. The very last vehicle off the line, a 2012-model-year Ranger, rolled out on December 16, 2011. It wasn't a plant in some backwater area either; it used to exceed Ford's average plant capacity. It was simply insufficient to keep existing in an industry that had shifted to leaner, more efficient production in other industrial regions.

This was part of a much broader, decades-long pattern, not an isolated case. A 2024 analysis by NAIOP, the Commercial Real Estate Development Association, shows that 60 percent of American auto manufacturing plants closed from 1979 to 2011, with almost three-quarters of those closures occurring in communities where the auto plant was one of the top three employers. Translation: the death of the Ford plant wasn't a Minnesota story. It was actually a national one with a river view.

Turning a graveyard of jobs into a pile of gravel

A century-old factory building is not like a garage building. Ford worked on asbestos abatement and the removal of underground storage tanks for years; as per a 2016 MinnPost report on the redevelopment, Ford also ground up about 300 million pounds (150,000 tons) of concrete from demolished buildings to reuse it in the capping material, rather than truck it to a landfill. Practical, sure. Also a little poetic: The same concrete that previously supported an assembly line is now under the foundations of new apartments.

Why should this matter

The Harvard Joint Center for Housing Studies' "State of the Nation's Housing 2025" report found that the median U.S. home price hit a record $412,500 in 2024, a price that would require roughly $126,700 in annual income to afford comfortably. Against that backdrop, turning a 122-acre dead factory into housing stops being a charming Midwestern story and becomes relevant to anyone priced out of their own zip code. This type of adaptive reuse: old industrial property converted into real residential use, is exactly the kind of supply-side solution that's been getting attention as one of the few real levers against the affordability crisis. And it's working here, gradually: the development on the old Ford site, called Highland Bridge, is designed to eventually bring roughly 2,600–2,800 housing units plus retail and green space to land that would otherwise still be sitting fenced-off and contaminated.

As of 2026, Highland Bridge is still very much a work in progress rather than a finished neighborhood: construction broke ground in 2020, stalled between 2022 and 2025 amid high interest rates and softer demand, and has since resumed, with the site now roughly half built out. A new phase along Ford Parkway: apartments, retail, and a daycare, is expected to wrap up by the end of this year. The project has taken more than a decade of environmental remediation, city coordination, and financing, and it's not a repeatable "magic bullet"; it's closer to a best-case scenario that required a dedicated corporate owner and a city government both willing to stay engaged for years at a stretch. That's not the case for most of the thousands of abandoned industrial facilities in the Rust Belt, which instead sit vacant behind chain-link fences, drawing no tax revenue and housing no one. The Ford site is more of a reminder of what it actually takes, in money and years, to reverse decades of industrial abandonment. The housing shortage doesn't stem from millennials, it stems from how few places in America are willing to do what St. Paul did with its old car factory.
