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.
Patna
The city is served by several major road highways and state highways, including National Highways 19, 30, 31, and 83. Asia's longest river bridge, the Mahatma Gandhi Setu (built 1982), is located in Patna and connects the city to Hajipur across the Ganga. In recent times, the bridge has been witnessing major traffic chaos and accidents due to exceeding number of vehicles passing over it and regularly overloading the structure. A new six lane road bridge across the Ganges parallel to Mahatma Gandhi Setu is proposed which would connect Kacchi Dargah in Patna City to Bidupur in Vaishali district, which will be the longest bridge in India after completion.
