Andean Suspension Bridges
1. Who is/was responsible for the construction of, as well as the maintenance and
upkeep of, the bridges? (4 pts)
The inception and perpetuation of the Inca suspension bridges were predominantly
entrusted to the indigenous communities domiciled in the strategically positioned regions where
these architectural marvels found their purpose. The Inca Empire orchestrated a labor system
known as "mit'a," which revolved around collective contributions from these communities. In
this paradigm, communities bore the obligation of furnishing their labor for state-driven
endeavors, with this communal commitment serving as the bedrock of suspension bridge
construction. Local communities, in addition to their labor, frequently supplied indispensable
materials requisite for the bridge's erection. The Inca civilization's organizational skills and the
synergistic combination of infrastructure development with the active involvement of local
populations were highlighted by this collaborative ethos.
2. Specifically describe one of the bridges discussed in the text, do you think it is
similar to the design of more contemporary suspension bridges, such as the Golden
Gate Bridge? (4 pts)
The Q'eswachaka bridge appears as a prominent example of these historic architectural
accomplishments in Brian S. Bauer's Chapter 17. While there are some similarities between the
Q'eswachaka bridge and modern suspension bridges, particularly in the context of their shared
use of suspended walkways, there are also significant differences in the construction materials
they use. The Q'eswachaka bridge brilliantly displays the ingenuity that typified the Inca culture
by being constructed from materials that were readily available nearby, notably braided grass and
fibers. Modern suspension bridges, such as the well-known Golden Gate Bridge, employ cutting-
3
edge engineering methods and sturdy steel cables, which are representative of the advancement
in building materials and construction procedures over time.
3. Have you ever crossed a suspension bridge like this? What are some of the risks or
issues with this type of bridge? Would you be confident crossing such a bridge?
Why or why not?(4 pts)
Reflecting upon personal experiences, I have had the privilege of traversing suspension
bridges in the past, and they carry inherent perils. These bridges can sway gently with the breeze
or the movement of individuals, which, while not intrinsically perilous, can be disconcerting for
some. Furthermore, the materials and construction methodologies employed in these bridges
exhibit substantial variance, and the upkeep of older suspension bridges can occasionally become
a point of concern. The confidence associated with traversing such a bridge is largely contingent
upon its structural integrity, the implementation of safety measures, and individual levels of
comfort.
4. Have you ever participated in community project like this? Whether you have or
not, discuss what you think the pros and cons of this type of labor are? (4 pts)
While I have not personally participated in a community endeavor akin to the Inca
bridge-building endeavors, the advantages and drawbacks are discernible. On the affirmative
side, these projects cultivate a profound sense of communal cohesion and shared responsibility.
They also serve as custodians of cultural heritage, ensuring that time-honored engineering
practices endure through successive generations. However, on the opposing spectrum, potential
pitfalls emerge, including the physical rigors of labor, conceivable safety hazards entailed in
labor-intensive construction, and the imperative for a delicate equilibrium between heritage
4
preservation and the incorporation of modern safety standards to ensure the longevity and safety
of such infrastructure.
