吴淞江
From 2007-2010, the Bund Tunnel was constructed under the Bund and the mouth of the Suzhou Creek. The construction of the tunnel was designed to relieve the heavy traffic through the Bund area. It rendered obsolete the late 20th century concrete Wusong Road Gate Bridge at the mouth of Suzhou Creek, which had impacted the streetscape and sightlines in the Bund area, allowing it to be removed. The tunnel replaced the road transport function of the bridge (and its water control function was replaced by the new Jinshan Road Gate). The concrete road bridge and flood gate, which was built to the west of Garden Bridge to relieve traffic from the historic bridge, was criticized by some for affecting the historic views between Garden Bridge and landmarks further up Suzhou Creek (such as the General Post Office Building). Wusong Road Gate Bridge was demolished in 2009, prior to the completion of the Bund Tunnel.
