粉嶺公路交匯處同粉嶺公路交匯。係公路嘅第一個交匯處，政府無幫佢正式改名，而佢嘅特點係用一個U字型嘅橋樑係龍山同和合石中間嘅山峽起咗一個交匯處，可以係呢度向南行跟住粉嶺公路同埋吐露港公路去到大埔，沙田，北區，元朗同埋九龍。而係粉嶺公路入嘅話就可以去到打鼓嶺同埋沙頭角。
Fanling Highway Interchange and Fanling Highway Interchange. This was the first interchange of the highway, and the government did not help him to officially change the name, but it was characterized by a U-shaped bridge that was an interchange between Lung Shan and Wo Hop Shek, which could be a southbound junction with Fanling Highway and Tolo Highway to Tai Po, Sha Tin, North District, Yuen Long and Kowloon. Instead, if you enter the Fanling Highway, you can go to Ta Kwu Ling and Sha Tau Kok.
