Bridges of this type were useful since the Inca people did not use wheeled transport – traffic was limited to pedestrians and livestock – and they were frequently used by Chasqui runners delivering messages throughout the Inca Empire.
Why were roads and bridges so important to the Inca empire?
Why were roads and bridges so important to the Inca empire? … They served as examples of the empire’s wealth, inspiring awe in newly conquered people. Their construction provided important jobs for the empire’s citizens. They allowed horses to easily cross the Andes Mountains for the first time.
Why were suspension bridges important in the Inca empire quizlet?
There were two suspension bridges, one for the commoners and one for the nobles. They were used to cross dangerous valleys. They were made out of reeds and grass with wooden floors.
Why is the suspension bridge important?
This helps to stiffen the deck and reduce the tendency of the roadway to sway and ripple. Suspension bridges can easily cross distances between 2,000 and 7,000 feet (610 and 2,134 meters), enabling them to span distances beyond the scope of other bridge designs.
Did the Incas used hieroglyphics?
The Inca did not use any form of hieroglyphics. The Inca used a series of knots and strings, called Quipu, to record data, information, and history….
Why did the Incas not use the wheel?

What is bad about a suspension bridge?
Disadvantages. Considerable stiffness or aerodynamic profiling may be required to prevent the bridge deck vibrating under high winds. The relatively low deck stiffness compared to other (non-suspension) types of bridges makes it more difficult to carry heavy rail traffic in which high concentrated live loads occur.
