Before there were cars, America’s country roads were unpaved, and they were abysmal. Back then, roads were so unreliable for travelers that most state maps didn’t even show them. This all started to change when early cyclists came together to transform some U.S. travel routes, and lay the groundwork for the interstate highways we use today.

Through the 1880s, spring and fall rains routinely turned dirt lanes into impassable mud pits that brought rural life to a standstill, stranding farmers at home with their produce and leaving grocers’ shelves bare. In the summer, the roads bore deep, sunbaked ruts; in the winter, treacherous ice slicks. The nearby farmers who were responsible for maintaining these roads didn’t have the means or desire to pave them, or even to post signs identifying them.

City streets weren’t much better. Though many were paved with cobblestones or wood blocks, they were also slashed through with trolley tracks and scattered with trash and horse manure. In 1892, British novelist Rudyard Kipling savaged New York’s “slatternly pavement” in a travel essay, calling the city’s uneven, stinky streets “first cousins to a Zanzibar foreshore.”

As soon as American cyclists began riding high-wheelers outdoors, they began kvetching about the roadways. “The majority [of Americans] do not know what a good road is,” wrote one rider in 1882, “and their horses—who do know and could explain the differences in roads—are debarred from speaking.”

Cyclists, however, could speak— and organize. Since high-wheel bicycles cost many times the average tradesman’s weekly wages, they were affordable only to the well-to-do, and the first bicycle clubs were upper-crusty fraternities for racing and socializing.

The groups quickly developed a political agenda, as cyclists had to fight for the right to ride. Police routinely stopped riders and shooed them off city streets, inspiring cyclists to join together and press for access to public thoroughfares. A national coalition of clubs called the League of American Wheelmen (LAW) came to lead these efforts.

Early court cases went against bikers. In 1881, three cyclists who defied a ban on riding in New York’s Central Park were jailed. But the cyclists eventually prevailed, and in 1890, the landmark Kansas case Swift v. Topeka established bicycles as vehicles with the same road rights as any other conveyance.

By then, the bicycle had undergone another transformation. Makers had discovered that, by using a chain and sprockets, they could make a wheel rotate more than once with each turn of the pedals. Wheels got smaller again, seats got closer to the ground, and the so-called “safety bicycle” — cushioned by new, air-filled tires — started selling like mad. A safety bicycle looked pretty much like a modern commuter bike, and by the early 1890s, more than a million Americans were riding them. With that many cyclists on the road, the demand for smoother roadways began to go mainstream.

Farmers weren’t on board yet, though. If better roads meant more unpaid work for them, most preferred the status quo. But then cyclists launched a full-bore PR campaign, one of the first of the modern era. Both in books and in a new monthly magazine called Good Roads, the LAW made the case to farmers in pocketbook terms.

Because pulling loaded wagons through muck or over ruts required extra horsepower, American farmers owned and fed at least two million more horses than they would need if the roads were smooth, LAW official Isaac B. Potter informed his rural reader. “A bad road is really the most expensive thing in your agricultural outfit,” he wrote. Potter argued that farmers deserved a cut of their urban countrymen’s taxes to pay for road paving. Many farmers were convinced, and began to work with cyclists to lobby state and local governments for better roads.

In mid-1892, Colonel Albert A. Pope, a leading bicycle manufacturer, printed thousands of copies of a petition demanding that Congress create a federal department to promote “knowledge in the art of constructing and maintaining roads.” He enlisted cyclists’ help to collect signatures and return signed copies, which he pasted into an enormous scroll.

Pope delivered this scroll to the U.S. Capitol in 1893, displaying it on a pair of hand-cranked oak spools that stood seven feet high. The so-called “monster petition,” now housed in the National Archives, bore 150,000 signatures. That same year, Congress authorized the creation of the Office of Road Inquiry, a two-man fact-finding operation that was a precursor to the Federal Highway Administration.

In 1896, the U.S. Postal Service further boosted rural support for good roads by launching the first rural free delivery routes. Rather than having to trek miles over iffy roads to the nearest post office to check for mail, farmers could now receive the same daily drop-off service as city residents. The catch was that the postmaster would authorize home delivery only if the local roads were passable, a strong incentive for farmers to see that they were.

As roads improved, city-dwellers increasingly used bikes to explore the flyover country of their day: the terra incognita between railroad stations. Wayside inns that had averaged one guest a week for years were suddenly overrun with wheelmen, some of whom installed signposts and created road maps to help other cyclists find their way.

This didn’t last long, though. By the end of the 1890s, the bicycle boom had collapsed, and fashionable swells had moved on to other passions. Working people in cities still used bikes for commuting or making deliveries, but the touring fad and the power of the bicycle lobby were done. Nevertheless, when automobile tourists took to the roads in large numbers in the 1910s and 1920s, they often found the way marked, mapped, and paved by cyclists who had come before.
