Highway
Major highways are often named and numbered by the governments that typically develop and maintain them. Australia's Highway 1 is the longest national highway in the world at over and runs almost the entire way around the continent. China has the world's largest network of highways followed closely by the United States of America. Some highways, like the Pan-American Highway or the European routes, span multiple countries. Some major highway routes include ferry services, such as U.S. Route 10, which crosses Lake Michigan.
Texas State Highway 99
State Highway 99, also known as the Grand Parkway, is a highway in Texas, United States that opened its first section in 1994. When State Highway 99 is complete, it will be the longest beltway in the U.S., and the third (outer) loop within Houston–The Woodlands–Sugar Land metropolitan area, with Interstate 610 being the first (inner) loop, and Beltway 8 (Sam Houston Tollway) being the second (middle) loop. The proposed loop has been divided into 11 separate segments for construction and funding purposes.
