Are all multi-lane roadways included in the Highway Transportation System?

The assertion that not all multi-lane roadways are included in the Highway Transportation System is accurate. The Highway Transportation System is a broad framework that encompasses various types of transportation infrastructure, including highways, roads, streets, and transit systems designed for vehicular movement. However, this system specifically focuses on roadways designated for public use, typically emphasizing major thoroughfares such as interstates and state highways, as well as urban roads that facilitate significant traffic flow.

Multi-lane roads can indeed exist that are not classified as part of this system. This might include certain local or privately maintained roads that have multiple lanes but do not serve a larger connectivity function or fall under the management of state or federal transportation agencies. The inclusion criteria for the Highway Transportation System prioritize roads that are integral to national and regional transportation strategies, emphasizing efficiency, safety, and connectivity for all users. Thus, it's clear why the statement is considered false.
