The tunnel project, which starts at Xinghai Street in the west (including the intersection of Xinghai Street) and ends at Nanshi Street in the east (including its intersection, extends for about 5.35 kilometers, among which 3 kilometers are fully under the lake. The main line of the tunnel is a two-way 6-lane expressway with a designed speed of 50 kilometers per hour. In order to fully protect the unique landscape of Jinji Lake, the tunnel is constructed with an open-surface method in a bid to ensure that the lake’s natural landscape cannot be harmed.
