Rainbow Boulevard is a main roadway located in southeastern Wyandotte County and northeastern Johnson County, Kansas. It is an undivided four-lane roadway with a posted speed limit of 35 mph that runs north–south.[1]
Its northern terminus is just south of Interstate 35 at Southwest Boulevard in Kansas City, Kansas. Its southern terminus at Shawnee Mission Parkway in Mission Woods, Kansas.
Rainbow Boulevard was named to commemorate the service and sacrifice of the men of Rosedale and the Kansas City metropolitan area in World War I. Upon America entering the war, it was decided that the first division of National Guard troops to be called up should be drawn from as many states as possible. The new division was designated the 42nd United States Infantry Division and allotments for twenty-six states were drawn up, a mixture prompting Secretary of War Baker to informally christen the 42nd the "Rainbow Division."[2]
