And there in South America an imperial highway ran from Cuzco to Ecuador, and was built
by a race less fearful of the lofty places and mighty canyons of the Andes, and
anciently it was more direct than the modern haphazard route. This well-built
and highly acclaimed system of roads has long been considered the most
remarkable road and highway system in the Western hemisphere.
These
roads, which the Spaniards called "the longest and grandest in the
world," can still be clearly seen today.
And though partly destroyed, there are numerous references to them
recorded in diaries and journals of the early conquistadors that ravaged this
land. They found roads from Chile to
Ecuador that were paved and had steps up inclines with rest places, suggesting
they were built for human beings and pack animals.
Hernando
Pizarro said of these roads: "The
mountain roads are really something worth seeing. Such magnificent roads can be seen nowhere in
Christendom in country as rough as this. Almost all of them are paved."

bridges that stretched across numerous canyons and rivers. Note in the left
image the yellow arrows point to the two original rock stanchions that secured
the ropes in B.C. times and still existed when the Spaniards arrived, and still used today
Considering
the mountainous regions of the Andes, the highway system built encompassed some
of the most magnificent bridge systems ever devised. According to the ancient
chronicler of the Spaniards who saw all this first hand, where the road crossed
the Vilcas River (Pampas), one side of the river to the other there were two
rows of stone piles, stout and deeply buried, on which lay the bridge, which
was made of twisted withes, like well ropes for drawing up water with a pulley.
The bridges made in this way are so strong that horses can gallop over them as
though they were crossing the bridge of Alcantara or Cordoba. Pedro Sancho, the
conquistador scrivener, crossed this bridge in 1534 and claimed it was 360
Spanish feet long, and wide enough for two horses to pass abreast. E. G. Squier
crossed this bridge in 1864 and said it was 125-feet above the roaring river
and stretched 250 feet across, mounted on cabyua cables as thick as a man's
body, which were renewed every two years.

repaired; Right: Road down into a deep Peruvian valley. Note the switchback
design of the road. Also note that the top of the road is paved with stones as
are the switchbacks
The
main arteries of these roads went from Quito, in Ecuador, to Cuzco, in Peru, to
Chuquisaca, in Bolivia, then deep into Chile and back along the coast of
Ecuador for a total distance of over 5,000 miles. This route followed by the
road was in use over a thousand years before the advent of the Incas and were
used by the army, travelers, by llama transport herds, and by relay messenger
runners. This network of runners, called chasquis,
were provided by each community, which was responsible to place runners along the
road to await for dispatches. There were post houses at regular intervals
called tambos, each consisting of a
few enclosures, and each man ran a short
distance at breakneck speed to deliver the dispatch over his brief area of
responsibility. Though early explorers
only covered about 2,500 miles of the roads, it is claimed they measured close
to 10,000 miles in length.

No
obstacle was too great in building these roads. Some were built along the side
of steep mountain cliffs by building up an outer rock wall and creating a level
road (today we cut away the cliff with huge machinery to provide a similar
level road), and river spans were sometimes bridged with wood (as shown above).
One
of the ancient longitudenal highways, later called the capac-nam (Royal Road)
by the Incas, extended from 1º north latitude to 35º south latitude, some 3,200
miles in length from Ecuador to Chile. The coastal road, which runs from
northern Peru to central Chile, where it joins the Andes road, has at least
eleven lateral roads connecting the two main highways. It is said that the
world's two great early road systems were those of Peru and Rome. The Peruvian
roads, like those of Rome, had mile markers and an average width of thirty-five
feet though they were only used for foot traffic (a modern U.S. two-lane
highway is 35-feet across).
Pedro
Ciega de Leon in 1548 said of these highways:
"I believe since the history of man, there has been no other
account of such grandeur as to be seen on this road. The road is well constructed, on the
inclining mountains well terraced, through the living rock cut along the
river-banks by retaining walls, in the snowy heights built with steps and resting
places and along its entire length swept cleanly and cleared of debris...with
post stations and storehouses at intervals along its length.
Baron
Alexander von Humboldt, of whom the Humboldt (Peruvian) Current is named, said
these roads were "the most useful and stupendous works ever executed by
man." And William Prescott said, "the road was conducted over
pathless sierras buried in snow; galleries cut for leagues through living rock;
rivers were crossed by means of bridges that swung suspended in the air;
precipices were scaled by stairways hewn out of the native bed-rock, all
difficulties which might appall the most courageous engineer of modern
times." The Royal road of the Chincha-suyu, when seen by Europeans, was
thought to be the longest continuous road in the world, and of which Pedro de
Cieza de Leon said: "I doubt there
is record of another highway comparable to this running through deep valleys,
over high mountains, through piles of snow, quagmires, living rock, and across
turbulent rivers.
