Answer:
Improved and expanded
Step-by-step explanation:
The advent of the Model T Ford in 1908 precipitated a major transformation in the sphere of transportation. Prior to this, roads were chiefly designed for the transit of horse-drawn carriages, cyclists, and foot traffic.
However, the emergence of the automobile necessitated a comprehensive reevaluation and overhaul of the existing road system to facilitate this novel method of conveyance.
The Model T, colloquially christened the "Tin Lizzie", although not the inaugural automobile, wielded substantial influence in its nascent years. The key to its success lay in its affordability, placing it within the financial reach of middle-class Americans.
This democratization of vehicle ownership resulted in a pronounced surge in the number of motor vehicles on the road, thereby instigating a heightened demand for an improved road infrastructure.
Roads underwent a series of upgrades, including paving for enhanced smoothness, expansion to accommodate increased traffic, and the creation of highways to establish connectivity between cities and towns.
This transition was not instantaneous; in fact, a significant number of roads remained unpaved well into the 1920s and 1930s. Nevertheless, by the midpoint of the 20th century, the visage of American infrastructure had undergone a radical metamorphosis, largely attributable to the pervasive adoption of automobiles, with the Model T Ford being a catalytic agent in this transformation.
