What is the first national roadway commonly known as?

The first national roadway is commonly known as the National Pike, also referred to as the Cumberland Road. This roadway was crucial in the early 19th century, as it served as one of the first federally funded highways in the United States, facilitating westward expansion and commerce. Its designation as a national roadway highlights its significance in connecting different regions of the country and enabling settlement and trade. The National Pike served as a vital thoroughfare for settlers and travelers moving westward, and its establishment marked a pivotal moment in the evolution of the U.S. transportation system.

Other choices do not accurately represent the first national roadway. National Highway 1 typically refers to the primary route in various countries but is not linked to the U.S. context. The National Turnpike and Transcontinental Highway refer to different concepts and timelines in U.S. roadway history.
