Whenever the commission shall deem it expedient to alter the established grade of any State highway, or portion thereof, within a city, the commission may by resolution declare its intention to alter such established grade, in which resolution must be briefly specified the grade to be established, together with a reference to a place where a profile map or maps showing the new grade and the old may be examined, and a place in the city where objections may be presented. A copy of such profile map or maps shall be furnished to the governing body having jurisdiction of any highway intersecting or intercepting any affected portion of the State highway.
