With the rapid development of the socio-economy and the growing demand for transportation, highways have become an indispensable and important part of the modern transportation network. The design of highway routes and interchanges is a key link in highway construction, which directly affects the efficiency, safety, and traffic smoothness of highways. Based on this, this article analyzes in detail the highway route design and the design of two common interchanges, in order to improve the highway route design and the quality and efficiency of highway construction.
