On June 29, 1956, President Dwight D. Eisenhower signed the Federal-Aid Highway Act of 1956, creating a 41,000-mile ‘National System of Interstate and Defense Highways’ funded with $26 billion in federal money. For most Americans, the interstates symbolized progress, speed, and Cold War security. For Native nations, however, the freeway era marked another chapter in a much longer story: the physical re-engineering of ancestral homelands. The same year the highway act passed, Congress also approved the Indian Relocation Act of 1956, pushing Native people off reservations and into the very cities the new freeways were built to serve. Together, these two 1956 laws reshaped Indigenous geography—from reservation lands sliced by asphalt to the rise of urban Indian communities that would ignite a new era of activism.
The Federal-Aid Highway Act of 1956: A Cold War Project on Indigenous Ground
Eisenhower had long championed modern highways. Stationed in Germany during World War II, he was impressed by the Reichsautobahnen, the network of high-speed roads the Nazi regime had built. After becoming president in 1953, he pressed for a comparable American system. Earlier legislation—the Federal-Aid Highway Act of 1944—had authorized a 40,000-mile ‘National System of Interstate Highways,’ but it provided no funding mechanism. The 1956 act solved that problem by raising the federal gasoline tax from 2 to 3 cents per gallon and channeling the revenue into a protected Highway Trust Fund. The federal government would cover 90 percent of construction costs.
The law’s stated purposes reveal the priorities of mid-century America: eliminating traffic congestion, enabling ‘speedy, safe transcontinental travel,’ and—chillingly, in Cold War language—ensuring that ‘in case of atomic attack on our key cities, the road net [would] permit quick evacuation of target areas.’ What the legislative record rarely mentioned was that these ’empty’ corridors were not empty at all. They crossed landscapes that Native nations had inhabited, managed, and held under treaty for generations—territories already diminished by a century of removal policies, allotment, and broken agreements, a pattern examined in depth in our article on the Indian Removal Act of 1830 and the forced removal of the Cherokee Nation.
From Dirt Roads to Freeways: The Land Beneath the Asphalt
At the end of the 19th century, there was roughly one motorized vehicle for every 18,000 Americans, and most roads were packed dirt or mud. Henry Ford’s Model T, introduced in 1908, changed everything: by 1927, Ford had sold nearly 15 million of them. But highway advocates also encouraged a myth that suited their purposes—that the lands the roads crossed were unoccupied wilderness awaiting improvement.
In reality, interstate corridors were routed through a living Indigenous geography. Survey teams crossed Anishinaabe (Ojibwe) territory in Minnesota and Wisconsin, Diné (Navajo) and Pueblo lands in the Southwest, and the sacred Black Hills region of the Lakota—terrain whose contested status is explored in our coverage of Native American resistance and the sacred Black Hills. Highway construction frequently disturbed or destroyed culturally significant sites. In some documented cases, freeway grading and fill operations cut through known burial grounds and village sites, a violation that continues to fuel contemporary disputes over the protection of ancestral remains, as discussed in our article on why grave robbers and developers keep targeting Native American burial sites.
The Indian Relocation Act of 1956: The Freeway’s Twin Policy
The highway act is best understood alongside its legislative sibling, also passed in 1956: the Indian Relocation Act (Public Law 959). This policy offered vocational training, transportation, and housing assistance to Native Americans willing to leave reservations for cities such as Chicago, Denver, Los Angeles, and Minneapolis. It was part of the broader Cold War ‘termination’ era, during which the federal government sought to dissolve tribal sovereignty and end the trust relationship with Native nations.
The consequences were profound and contradictory. Relocation programs often delivered on none of their promises—many relocatees found substandard housing, low-wage work, and isolation. Yet the program also concentrated thousands of Native people from diverse nations in the same urban neighborhoods, many of which were being physically carved up by the very interstates the relocation promised would connect people to opportunity. Out of this crucible emerged pan-Indian urban identity and new political organizations.
Freeway Revolts and the Rise of Urban Indigenous Activism
Eisenhower’s interstates faced unexpected resistance. The first victory for the anti-freeway movement came in San Francisco in 1959, when the Board of Supervisors halted the double-decker Embarcadero Freeway along the waterfront. During the 1960s, activists in New York, Baltimore, Washington D.C., and New Orleans stopped additional plans, leaving abrupt dead-end segments activists mocked as ‘roads to nowhere.’ In city after city, freeways displaced residents from their homes, sliced neighborhoods in half, and accelerated abandonment and decay.
Urban Indian communities felt this displacement with particular force. A striking convergence of facts marks this era: the American Indian Movement (AIM) was founded in Minneapolis in 1968, in neighborhoods fundamentally shaped by relocation and by the disruption of urban community life. Two years later, in 1969, Native activists from the Bay Area occupied Alcatraz Island—a former federal property—invoking the 1868 Treaty of Fort Laramie’s provision allowing Lakota people to claim surplus federal land. Read alongside the history of Native American solidarity at Alcatraz, the freeway revolts and the Red Power movement appear as parallel responses to a federal infrastructure regime that treated both city neighborhoods and Native lands as expendable right-of-way.
Interstate Facts and Their Indigenous Dimensions
- The Interstate Highway System ultimately grew beyond 46,000 miles, far exceeding the original 41,000-mile authorization.
- I-90, at 3,020 miles from Seattle to Boston, is the longest interstate—crossing Anishinaabe, Lakota, Haudenosaunee, and Mohican-region homelands along its route.
- The designed geometry of interstates—controlled access, no cross-traffic, minimum four lanes—meant that once routes were set, affected communities had almost no leverage to change them.
- Interstate routes followed older corridors in many places, including railroad and trail alignments—routes that often traced ancestral Indigenous trade and travel paths, complicating the myth that Native people did not ‘use’ these landscapes.
Historical Context & Key Cultural Takeaways
The Interstate Highway System must be read within the long arc of federal land policy toward Native nations—removal, reservation, allotment, termination, and now infrastructure-driven displacement. Scholars and tribal historians emphasize three core insights. First, the 1956 highway act and the 1956 relocation act operated as complementary instruments of the termination era: one re-engineered the physical landscape, the other re-engineered the demographic one. Second, the freeway revolts of the late 1950s and 1960s demonstrated that infrastructure was not inevitable—organized community resistance could and did stop destructive routes, a legacy of activism later embraced by Native communities challenging mines, pipelines, and highway expansions near sacred sites today, in the tradition of campaigns like those surrounding Teddy Roosevelt-era conservation displacements. Third, the interstates paradoxically strengthened Indigenous unity: by concentrating relocatees in shared urban neighborhoods, they created the conditions for pan-Indian organizations such as AIM and the Red Power movement. The story of the interstates is thus not only a story of concrete and gasoline taxes—it is a story of sovereignty, survival, and the enduring claim of Native nations to their ancestral lands.
Frequently Asked Questions
When was the Interstate Highway System created?
President Dwight D. Eisenhower signed the Federal-Aid Highway Act of 1956 on June 29, 1956, authorizing a 41,000-mile network funded by a federal gas tax increase from 2 to 3 cents per gallon, deposited in the Highway Trust Fund, with the federal government paying 90 percent of construction costs.
How did the interstates affect Native American communities?
Interstate routes crossed treaty lands, reservation boundaries, sacred sites, and ancestral burials, frequently destroying or fragmenting culturally significant places. In cities, freeways destroyed neighborhoods where Native relocatees—many brought under the 1956 Indian Relocation Act—had settled, contributing to the urban conditions that gave rise to the American Indian Movement in 1968.
What is the connection between the 1956 highway act and Native American policy?
Both laws date from the same congressional session and the same policy environment: the Cold War ‘termination era,’ when the federal government sought to end its trust responsibility to tribes while reshaping national geography through massive infrastructure spending. The acts together accelerated both the physical occupation of remaining Native lands and the urbanization of Native populations.
Did Native Americans ever successfully resist interstate construction?
Community resistance did halt sections of the system, starting with San Francisco’s Board of Supervisors cancelling the Embarcadero Freeway in 1959 and continuing through the 1960s in New York, Baltimore, and Washington D.C., producing the so-called ‘roads to nowhere.’ These freeway revolts paralleled and inspired later Native-led campaigns to protect sacred landscapes and burial sites from highway and infrastructure projects.
What is the longest interstate highway?
I-90 is the longest route in the system at 3,020 miles, running from Seattle, Washington, to Boston, Massachusetts, and crossing numerous Indigenous homelands along the northern tier of the United States.
Cultural Legacy and Modern Preservation
Today, more than 46,000 miles of interstate carry over a quarter-billion American vehicles, an almost unimaginable contrast to the dirt roads of 1900. But Native nations continue to live with, contest, and adapt to the corridors imposed across their lands in the 1950s and 1960s. Tribal historic preservation offices—strengthened by federal law—now work to identify and protect burial sites, sacred landscapes, and cultural resources during every highway rebuild and widening project. The freeway that once sliced through Indian Country without consultation has, in the modern era, become a site of formal government-to-government consultation under the National Historic Preservation Act. The interstates remain a monument to federal power over land; the sustained Indigenous response to them remains a monument to something older and stronger: the enduring relationship between Native peoples and the places the concrete merely covers.
