Abstract With the vigorous development of the highway construction projects, the scale and complexity of highway projects increase greatly. In course of the highway projects’ construction and operation, there are many varied uncertain factors during the construction period. Meanwhile, during the operational period, due to the uncertain factors of technology, materials, equipments and others, the potential accidents will impact on the environment. There are also certain risks in the transport of dangerous goods, which may cause the varied degrees of damage for the surrounding environment. Therefore, in order to strengthen the road of environmental protection and guarantee to improve the overall quality of highway construction and operation, we need to carry out the environmental risk assessment of highway construction projects , strengthen the management of environmental risks, reduce the risk of environmental accidents and reduce the loss of environmental risks This study describes the concept, classification and major coverage of the environmental management, risk management and environmental risk, and analyzes the characteristics and the management content of highway construction projects. In the paper, the environmental risk factors are classified according to construction period and operation period of highway construction projects, and the job grading and scope of evaluation for environmental risk assessment are proposed. We investigate significance and major coverage of social stability risk in the highway projects, and propose the assessment process of social stability risk. The environmental risk preventive measures are proposed, which are used to strength
