Explanations:The Harappan civilization, also known as the Indus Valley Civilization, was one of the earliest urban civilizations in the world, flourishing between 3300 and 1300 BCE. This civilization is renowned for its advanced urban planning and construction techniques, which were far ahead of their time. One of the key features of Harappan cities was the use of brick streets, which were a significant aspect of their urban infrastructure.
Harappan cities were meticulously planned with a grid-like layout, featuring wide and straight streets that intersected at right angles. These streets were made of bricks, which were carefully laid to form a durable and well-constructed surface. The use of bricks for streets was a testament to the advanced engineering and construction skills of the Harappans. Bricks were not only used for streets but also for the construction of houses, public buildings, and drainage systems, showcasing the civilization's proficiency in brickwork.
The choice of brick as a construction material for streets was strategic. Bricks provided a solid and stable surface that could withstand the wear and tear of daily use, including the passage of carts and other wheeled vehicles. Additionally, brick streets were easier to maintain and clean compared to dirt roads, which could become muddy and difficult to navigate during rainy seasons. The durability and practicality of brick streets made them an ideal choice for the urban environment of Harappan cities.
It is important to note that the use of brick streets was not limited to the major cities like Mohenjo-daro and Harappa but was also a feature of smaller towns and settlements within the Harappan civilization. This uniformity in urban planning and construction techniques across different settlements highlights the sophistication and organization of the Harappan society.
In contrast, options such as dirt roads, wooden paths, and gravel roads were not commonly used in Harappan cities. Dirt roads would have been less durable and more prone to erosion, while wooden paths would not have been suitable for the heavy traffic and weather conditions. Gravel roads, although more durable than dirt roads, were not as stable and long-lasting as brick streets.
Thus, the use of brick streets in Harappan cities reflects the advanced urban planning and construction techniques of the civilization, which contributed to the longevity and functionality of their urban centers.
