In cross section design of urban road, assuming that the width of subgrade is 43M, how to arrange cross section
I don't know if this is OK, 3.0 m sidewalk + 3.5 m non motorized Lane + 2.0 m motorized non motorized divider + 0.25 curb + 2 * 3.25 m motorized Lane + 3.75 m Expressway + 0.25 curb + 4.5 m central green belt + 0.25 curb + 3.75 m Expressway + 2 * 3.25 m motor vehicle + 0.25 curb + 2.0 m motorized non motorized divider + 3.5 m non motorized Lane + 3.0 m sidewalk
