Suzhou Creek
In the south, the tunnel begins on a stretch of South Zhongshan Road, which runs along the western bank of the Huangpu River, on the east side of the old Chinese city. It follows South Zhongshan Road and No. 2 East Zhongshan Road, crosses Yan'an Road, a major east-west artery (with a major exit to and from Yan'an Road), then follows East No. 1 Zhongshan Road through the Bund. At the northern end of the Bund, where the surface road joins the historic Garden Bridge to cross Suzhou Creek, the tunnel also crosses Suzhou Creek under the bridge. On the northern bank of Suzhou Creek, the tunnel briefly follows Daming Road, with another major exit leading east onto Changzhi Road, while the main tunnel veers west and joins Wusong Road.
