This article analyzes the method for designing routes in road reconstruction and expansion projects, using an actual engineering project as an example. This includes an overview of a specific road reconstruction and expansion project, an analysis of the preexisting road, the basic principles of the design road project, and an analysis of the design methods and steps. This study aims to offer some guidance for road reconstruction and expansion design.
