The empire known for its extensive road network called the Incan Roads was the Inca Empire, which thrived in South America from the early 15th century until the Spanish conquest in the 16th century. The Incan road system was an engineering marvel, facilitating communication, trade, and military movement across the mountainous terrain of the Andes. Stretching over 25,000 miles, these roads connected diverse regions and communities, showcasing the Incas' ability to unify their vast empire effectively. The roadways remain a legacy of the Incan civilization’s ingenuity.
