The invention discloses an inspection shaft cover for an urban road. The inspection shaft cover for the urban road comprises a rigid plastic grating plate. The rigid plastic grating plate comprises a thickened frame and a grating portion located in the thickened frame. The upper portion of the rigid plastic grating plate is covered with a rigid plastic plate. The periphery of the rigid plastic plate and the thickened frame are fixedly connected through bolts. The bottom of the rigid plastic grating plate is covered with the metal plate. The periphery of the metal plate and the thickened frame are fixedly connected through bolts. In this way, the inspection shaft cover for the urban road is simple and reasonable in structure, high in strength and good in safety, the metal plate is hidden in the inspection shaft cover and cannot be easily found, and therefore stealing of inspection shaft covers can be less.
