Under the guidance of the spirit of the National Conference on Ideological and Political Work in Colleges and Universities, curriculum ideological and political education has become a key measure to implement the fundamental task of moral education. Taking the course “Municipal Road Engineering Construction” as the research object, this paper explores the path of in-depth integration of curriculum ideological and political concepts with professional teaching. By excavating ideological and political elements such as engineering ethics, craftsmanship spirit, green development, and cultural confidence contained in the course, a trinity teaching system of “knowledge transmission - ability training - value shaping” is constructed. Combined with specific teaching practice cases, the implementation effect of curriculum ideological and political education is analyzed. Research shows that the integration of curriculum, ideological and political education not only improves students’ professional literacy but also strengthens their sense of social responsibility and professional identity, providing an effective paradigm for cultivating high-quality municipal engineering talents with “both moral and technical proficiency”.
