長堤喺廣州市南關、珠江北岸，係東西走向嘅。沿長堤大馬路、沿江路一帶，大致東起北京南路、西接人民南路，長約二公里。呢度喺清朝初期係珠江河道，後尾珠江沿岸淤積加劇，河灘發育，到咗清朝末年形成咗陸地。
The causeway is located in the south of Guangzhou City, on the north bank of the Pearl River, and runs east-west. Along the Long Causeway Road and Yanjiang Road, it is roughly from Beijing South Road in the east and Renmin South Road in the west, with a length of about 2 kilometers. In the early Qing Dynasty, it was the course of the Pearl River, and later the siltation along the Pearl River intensified, and the river beach developed, and by the end of the Qing Dynasty, land was formed.
