The south extension project of Xigang Road is an important part of the first bid section of the east-west extension project of Haibin Road, which is operated by the Municipal Engineering Construction Service Center of the Qinhuangdao Housing and Construction Bureau, with the length of 1.78km, the design speed of 50km/h on the main road, and 40km/h on the auxiliary road.
Running over the auxiliary road, the viaduct has two way 6 lanes, adopting cast-in-place concrete box girder and steel box girder of equal cross-section. The ground under the bridge is greened or paved. The auxiliary road on the ground is a two-way 4-lane, with public facilities such as rainwater drainage, sewage, water supply, pipeline integration, street lights, greening, and traffic engineering.
The Xigang Road extension project will become an important bond between the urban area of Haigang District and the Daonan area, which will play an important role in improving the travel of residents in the Daonan area and promoting economic development of the city.
