 On April 28, CCCC's subsidiaries CCCC Second Harbor Engineering Co., Ltd. and CCCC Second Highway Engineering Co., Ltd. won the bid for the project of Humen Second Bridge in Guangdong Province, with a total contract value of over 2.5 billion yuan.

With a full length of 2,724 meters, a contract value of 1.84 billion yuan and a construction period of 55 months, Lot S3 won by CCCC Second Harbor Engineering Co., Ltd. involves the east tower and anchor of Dasha aqueduct, the central approach, Haiou Island interchange, full-line box girder prefabrication and assembling, as well as auxiliary works; with a contract value of 700 million yuan and a construction period of 55 months, Lot S2 won by CCCC Second Highway Engineering Co., Ltd. involves the west tower and anchor and upper structure of Dasha aqueduct, the west approach, as well as the construction of the foundation and lower structure of Liudong interchange.

Designed by CCCC Highway Consultants Co., Ltd., the bridge has an expected total investment of over 10 billion yuan. With a main length of 12.9 kilometers, the bridge will be constructed according to the standards of eight-lane highways. The main line will be entirely constructed in the way of bridge construction and two grand bridges will be built: Dasha aqueduct is a double-tower single-span steel box girder suspension bridge with a main span of 1,200 meters, and Nizhou aqueduct is a 658m+1,688m double-tower double-span steel box girder suspension bridge. Both aqueducts have a width of 40.5 meters.

Due to the large scale, complex construction conditions and many influencing factors of Humen Second Bridge, key technical problems such as wind resistance, earthquake resistance, durability of the main cable, fatigue stress of decks of the steel box girder bridges and ultra-large-scale foundation pit excavation need to be resolved in design and construction. The bridge's construction will set a new record of span among Chinese suspension bridges and mark a new milestone in the Chinese bridge history.
