the Bund
the Huangpu River
Shanghai World Expo

Tens of thousands of Shanghai residents and tourists swarm the Bund after the city's landmark site reopens. The 2000-meter promenade that stretches along the west bank of the Huangpu River has taken shape, after nearly three years renovation work, just in time for visitors to Shanghai World Expo. A vehicular tunnel which runs beneath the promenade, aims to relieve the traffic congestion on the Bund itself.
经历近3年的改建和扩建后，外滩重新对外公众开放。沿浦江西岸延伸的2000米人形长廊已初露端倪，又恰逢上海世博盛会，数以万计的上海市民和游客蜂拥而至，到这城市地标观光游览。行车隧道穿行在沿江步道下，以缓解外滩交通拥挤。
