The Huanghai Second Bridge, a new channel for transportation of liquefied natural gas (LNG) from Yangkou Port in Rudong county, Nantong in East China's Jiangsu province is under full construction; a quarter of the work is already finished.

Huanghai Second Bridge is located within 30 meters of the east side of Huanghai Bridge, and is meant to supplement the dual-lane two-way original. When fully completed, the new bridge's four lanes are expected to double the traffic capacity of the previous crossing.

Both bridges take the name of the Yellow Sea (Huanghai) as Rudong borders the southern Yellow Sea to the east and north.

The second bridge is about 10.04 kilometers in length, of which the straight section is 8,508 meters and the curved section is 1,527 meters. The width is 13.1 meters. Linking areas are set at every three kilometers for vehicles to pass each other and turn around.

The construction began in mid-February and will be finished on August 30, 2022, according to Qiu Yuanyuan, deputy manager of the general contracting project department responsible for public-private partnerships (PPP) work of Yangkou Port of the China Communications 2nd Navigational Bureau.

As the "main artery" connecting the LNG energy center and the port area, the Huanghai Second Bridge project ranks high on the work agenda of the Yangkou Port Economic Development Zone.

Natural gas export from Sunshine Island where LNG development is deployed is dominated by gas transmission and the use of dedicated vessels for LNG transport. At present, during the peak time in a single day it can have nearly 200 vehicles full loaded with LNG, according to a local official.

In the future, with the expansion of Jiangsu LNG Phase III and the operation of the Jiangsu Guoxin Investment Group Limited project and others, the LNG loading volume will further increase.

At the same time, a number of industrial projects highly dependent on ports have successively settled in the port industrial zone, including one owned by Tongkun Group. They all set higher requirements for port throughput and carrying capacity of the connecting channels.
