The underwater foundation of a new bridge across the Huangpu River was completed on Monday, marking a milestone in the project to connect Minhang and Fengxian districts by 2020.

The 1.94 kilometer Kunyang Road bridge, the 13th bridge crossing the river, will connect Kunyang Road in Minhang and the Puwei Highway in Fengxian. It is expected to largely relieve the congestion on other cross-river bridges and thoroughfares in the southwest region of the city, said Shanghai Tunnel Engineering Co Road and Bridge Group, the city’s major bridge constructor.

A platform above the water measuring 800 square meters was completed in the middle of the Huangpu River on Monday.
