Nandu River
The northern part of Haikou City, the district of Haidian Island, is separated from the main part of Haikou by the Haidian River, a tributary of the Nandu River. The district is accessed by one of four bridges, the largest being Haikou Century Bridge, which connects the Guomao district with Haidian Island at the estuary of the Haidian River. From east to west the remaining three road connections are provided by the Renmin, Heping and Xinbu Bridges.
