The Last Mile.
How America Learned to Travel — and Why Some Journeys Still Stop Short.

Before roads: the first human journeys

Before European colonization, the continent already contained extensive systems of travel, exchange and communication. Over many millennia, people moved by foot along established paths, crossed rivers, built watercraft, and carried goods between communities. It would be historically inaccurate to describe these societies as isolated or transportation-less. The waterways of the Upper Midwest formed connective corridors long before the modern states of Minnesota, Wisconsin, Iowa, North Dakota and South Dakota existed. Transportation was not simply a question of speed: it was how families reached seasonal food sources, maintained alliances, shared knowledge, traded materials and visited relatives.

Geography shaped the choices. Rivers could connect settlements over great distances, while portages connected separate watersheds. A route that looks indirect on a modern road map might have been remarkably efficient by canoe. In prairie areas, walkers and later horse travelers moved along paths adapted to weather, terrain, safety and access to water. Routes changed across seasons; frozen rivers sometimes became winter corridors while open water enabled canoe movement. The absence of paved roads did not mean an absence of transportation infrastructure.

The record should be read with care: archaeological findings, Indigenous oral history and later written documents are different kinds of evidence. Exact dates for an individual path are not always recoverable. Any history of “the last mile” must begin with the people who understood these landscapes first.

Water as the earliest regional network

The Mississippi River, Missouri River, Red River and the Great Lakes connected communities and economic activity. Indigenous peoples, including Dakota and Ojibwe communities in areas now called Minnesota and Wisconsin, used water and overland routes suited to their homelands. Canoes, including birchbark designs in forested regions, allowed travel with cargo while remaining portable around difficult passages. Across the northern plains, horse travel and animal-drawn transport became important in later periods.

European fur-trade networks depended heavily on Indigenous geographic expertise, water routes and portages. Trading posts and settlements were often established where river systems offered access. Later steamboats connected river towns, carrying passengers, mail and freight, but their schedules were constrained by season, water levels and navigability. A boat terminal was itself only a node: passengers still needed to travel from the landing to a farm, home or community beyond the water.

The central last-mile challenge already existed: a regional corridor could bring someone close to a destination while leaving the final distance unresolved.

Red River carts, trails and stagecoaches

During the nineteenth century, Red River ox carts and wagon trails connected trading areas in what is now the Upper Midwest. The carts were adapted to long overland journeys and became associated with routes between the Red River settlement region and Saint Paul. They moved freight, supported trade and linked river and overland systems. The journeys could be slow and physically demanding, and their operation was shaped by weather and trail conditions.

Stagecoach and mail routes later offered scheduled or semi-scheduled movement among towns, trading centers and rail connections. A stagecoach was not equivalent to a modern taxi; travelers often had to reach a designated stop and were dependent on road conditions, available horses and an operator’s schedule. Travel was expensive and unevenly available.

This period demonstrates an enduring pattern: the transport method that connects two hubs is not necessarily the method that connects the hub to the final address. Modern intercity bus stops at highway restaurants echo that older distinction, even though the technology has changed.

Railroads reorder the map, 1850s–1900s

Railroads dramatically changed American travel during the nineteenth century. Rail service brought new opportunities for commerce and longer-distance passenger movement, while railroad companies and investors chose which settlements would be connected directly. Towns with stations could develop as freight and passenger centers; towns bypassed by a route could face new disadvantages. Railroads reduced some journeys from days to hours, but they did not connect every farm, village or medical facility.

The federal government influenced railroad development through land policies, legislation and infrastructure decisions, while private railroad operators determined much of the network and scheduling. A station became a powerful gateway to a region. From that station, passengers might walk, hire a carriage, arrange a wagon, or later take a taxi or bus. In winter, a seemingly short distance could still be a substantial barrier.

The history of the railroad is therefore also a history of transfers: train to streetcar, train to horse carriage, train to local bus, and eventually train to app-arranged ride. Each handoff is a potential break in the journey.

Streetcars, urban taxis and unequal access

As American cities grew in the late nineteenth and early twentieth centuries, horse-drawn streetcars and then electric streetcars expanded the range of daily travel. Electric streetcars could run frequent routes along fixed corridors, enabling workers to reach employment and families to live farther from central business districts. Their fixed routes could also leave people far from a stop, particularly outside built-up neighborhoods.

Taxicabs and hired cars added flexible point-to-point transportation in cities during the early automobile era. Yet a service that could reach individual addresses was not automatically affordable or available in sparsely populated areas. Density mattered: a driver might earn multiple fares in a compact city but face a long empty return after a rural drop-off.

The social history matters as much as the technical history. Policies governing land use, road building, transit access, segregation, disability access and service provision helped determine which neighborhoods and travelers benefited. Transportation systems distributed opportunity unevenly, and the consequences are still visible in contemporary travel patterns.

The automobile and the public-road revolution

Mass-produced automobiles and road improvement reconfigured travel in the twentieth century. Cars provided flexible trips without fixed train schedules, but they shifted expenses and responsibilities onto households: purchase price, maintenance, insurance, fuel and driver licensing. For residents able to drive, the automobile increased freedom of movement; for people unable to drive, car-oriented development could make ordinary destinations harder to reach.

Congress passed the Federal Aid Road Act in 1916, an early landmark in federal support for public roads. Later federal and state programs improved highways and linked transportation planning to national economic goals. The increasing availability of automobiles changed where businesses, schools and housing were built. Some services clustered around roads designed for cars rather than pedestrians or regular transit.

The same vehicle that solved one household’s transportation problem could amplify the difficulty faced by a neighbor without a vehicle. The modern last-mile gap is partly a byproduct of that long institutional shift.

Intercity buses and roadside passenger stops

Motorcoaches provided comparatively flexible intercity transportation over paved roads, and bus operators served routes that did not justify a passenger rail connection. From the 1920s onward, regional and national bus networks expanded, connecting cities and smaller communities. In many places, bus depots became social landmarks where travelers bought tickets, received schedules, waited inside and connected to local transportation.

Not every bus stop was a full terminal. Some were placed at hotels, drugstores, service stations or roadside businesses. If a traveler stepped off at a highway stop and needed to reach a town farther away, the bus had solved only part of the trip. A relative, local cab, hotel shuttle or other service was still necessary.

Over subsequent decades, service patterns changed with highway development, population shifts, operating costs and consumer travel choices. The disappearance of a staffed station can reduce access even when a bus route technically remains. Service frequency, ticketing, baggage accessibility, safe waiting areas and the availability of onward rides matter as much as a point on a network map.

1956: interstate highways remake the country

The Federal-Aid Highway Act of 1956 established the modern Interstate Highway System and a major long-term federal commitment to highway construction. The National Archives describes it as one of the largest public-works efforts in American history. Interstates increased access to distant markets and enabled long-distance bus and automobile travel. They also changed local economies by channeling traffic toward interchanges.

The benefits were not evenly distributed. Some highways cut through established urban neighborhoods and displaced residents. Other road alignments diverted travelers away from downtown streets and local businesses. Highways enabled new growth but often encouraged development at distances better suited to cars than to walking or scheduled public transit.

An interstate exit may be convenient for through-travel and inconvenient for the person whose destination lies many miles beyond the interchange. In this sense, high-speed infrastructure does not automatically produce door-to-door accessibility.

Commercial aviation and the airport ground gap

Commercial aviation made long-distance passenger travel faster across the twentieth century, yet airport access remained a separate transportation problem. A traveler arriving at MSP, Milwaukee, Fargo, Sioux Falls or Des Moines still must reach a residence, workplace, hotel, school or rural community. Airports link regions to national networks but do not by themselves provide comprehensive local transportation.

Airport bus systems, taxis, rental cars, public transit and private rides coexist with different prices, hours and geographic coverage. A traveler arriving after the final rural bus departure faces a different problem from someone going to a downtown hotel. A major airport can sit within a transportation-rich metropolitan area and still be a difficult departure point for a destination two counties away.

This is why the phrase “last mile” is not literally limited to one mile: in rural America, the final independent segment may be twenty, fifty or more miles.

1970–1971: saving passenger rail through Amtrak

As private railroad passenger operations struggled financially, Congress enacted the Rail Passenger Service Act of 1970 and created the National Railroad Passenger Corporation, known as Amtrak. Amtrak began operating most of its intercity routes in 1971. Preserving a national rail network was a federal policy choice, but the routes still reached selected stations rather than every community.

For the five-state region, rail lines remain essential pieces of a larger journey. Train connections can serve college trips, family visits, tourism and longer-distance travel. Reliability, timetables, station amenities and local ground transportation determine whether a train is an effective option for someone who does not drive.

A reliable passenger network is more than rails and trains. It is the entire chain from an origin address to a destination address, including connections that may be run by unrelated providers.

1960s–1990s: federal transit programs and accessibility

Federal transit assistance grew during the 1960s, initially with an emphasis on urban mass transportation. Federal law created the rural formula-grant framework now known as Section 5311 in 1978. This recognized that rural mobility had distinct economics: trips were longer, populations lower and fixed-route service often more costly per passenger. Federal support could help states and local systems provide service where fare revenue alone would not sustain it.

In 1990, the Americans with Disabilities Act created enforceable accessibility obligations, and transportation regulations introduced major expectations for accessible public transit and complementary paratransit. Accessibility is not only a matter of getting a bus or vehicle to an address; the equipment, boarding, scheduling, training and legal obligations also matter. The ADA changed the national understanding of transportation as a civil-rights issue.

These programs do not imply that every private carrier must provide every service. Public transit, complementary paratransit, non-emergency medical transportation, private taxis and intercity bus companies operate under different legal and funding frameworks. Readers should verify the rules that apply to a specific service.

What makes rural transportation different?

Demand is dispersed. A bus traveling between two metropolitan centers can carry many passengers, while an accessible route between farms, small towns and hospitals may require long detours or advance reservations. A driver sent from a neighboring county may spend more time repositioning than carrying a fare. In winter, even a scheduled trip can be affected by closures, ice, visibility and the availability of a safe stopping location.

A transportation gap can take several forms: there may be no service at all; a service may exist but operate only on weekdays; a bus may stop nearby but at an inaccessible roadside location; a provider may take a passenger outward but not offer a return; or a traveler may not be able to pay, schedule, lift luggage or transfer between vehicles. Each problem requires a different type of intervention.

Federal Section 5311 rules include an intercity bus component: states generally devote at least 15 percent of their annual rural formula apportionment to intercity bus development and support unless they certify that needs are adequately met. That requirement reflects policymakers’ concern that connecting rural communities to broader transportation networks is a public interest.

How researchers measure the last-mile gap

The Bureau of Transportation Statistics studies “reasonable access” to scheduled intercity bus, train and air service. Its 2021 analysis found that 85 percent of rural U.S. residents had reasonable access to at least one scheduled intercity transportation mode, leaving 15 percent without such access. When excluding the rural fringe near urban areas, the share without access rose to 25 percent. The measurement addresses proximity and service characteristics; it does not mean a ride is available on demand to every doorstep.

South Dakota stood out in the 2021 study: 62 percent of rural residents lacked reasonable access to scheduled intercity transportation. BTS also reported that rural access declined notably in South Dakota and Iowa between 2006 and 2021, in part because of intercity bus service losses. These are historical results, not a live 2026 service map.

A useful public guide should distinguish access from frequency, affordability and usable door-to-door travel. A county with a bus stop may still have poor practical access for a person living far from that stop. Meanwhile, a regional taxi or demand-responsive service may fill some gaps without appearing in a dataset that focuses only on scheduled intercity modes.

The digital era: rideshare, mapping and demand-responsive trips

Smartphones, digital maps, online payments and app-based dispatch changed the visibility and ordering of passenger transportation. In some places, rideshare apps expanded access to trips that once required a telephone dispatcher. In others, low driver density meant that the app could display no cars at all, especially at night, outside larger cities or for a long return trip. Technology can coordinate service; it does not create drivers where none are operating.

Modern transport planning also includes demand-response buses, vanpools, regional shuttles, intercity bus links, paratransit, on-demand taxis and public-private partnerships. Digital tickets and trip-planning tools can make connections easier, but rural broadband coverage, smartphone access, payment methods and accessibility still affect who benefits.

The practical question is no longer simply “is there a route?” It is whether the complete journey can be planned, paid for, safely reached and reliably finished.

2021–2026: Congress returns to the rural mobility question

The Infrastructure Investment and Jobs Act, enacted as Public Law 117-58 in November 2021, authorized substantial federal transportation investment, including roads, public transit and passenger rail. As the end of that authorization period approached, the 119th Congress considered reauthorization proposals. The legislative process is ongoing; a committee-approved bill is not the same thing as a law.

On March 3, 2026, the Investments in Rural Transit Act (S. 3978) was introduced in the Senate. Its sponsors included legislators from Minnesota, South Dakota and Wisconsin. The proposal addresses the federal share of rural transit operating costs. It was referred to committee; the cited official legislative text is an introduced bill, not an enacted statute.

On May 22, 2026, the House Transportation and Infrastructure Committee approved the BUILD America 250 Act (H.R. 8870) in committee. Its scope includes highways, bridges, transit, passenger rail and safety programs. Congressional Budget Office analysis was published in September 2026. On September 24, 2026, the Improving Rural Transportation Act (H.R. 10598) was introduced to propose a demonstration program relating to multimodal transportation technologies. Each measure has a distinct purpose and must be tracked independently for changes in status.

These contemporary proposals continue a debate that has lasted more than a century: how much transportation capacity should be treated as a shared public investment, and how should scarce resources serve households whose trips are too widely dispersed for high-frequency commercial service?

What the next last mile might look like

Possible strategies include better timed bus-to-train connections, mobility management, demand-responsive public transit, coordinated medical trips, reliable rural intercity bus links, accessible vehicles, safe waiting locations and improved passenger information. Automated and connected vehicle technologies may eventually affect service economics, but technology claims should be evaluated against practical costs, winter conditions, accessibility and safety.

Many improvements are organizational rather than futuristic. A single clearly identified bus stop with shelter, current schedules, a safe walkway and a dependable onward connection can be more useful than an elaborate travel app with incomplete service data. Regional agencies can also publish understandable instructions about eligibility, booking windows, cancellations and transfer responsibilities.

The historical lesson is straightforward: people have always built networks to move across distance. The remaining challenge is to make those networks connect for people whose final destination is not on the main line.
