The corridor of champions is along South Dakota Highway 34 as three of the seven state champions are located on SD-34.
The Madison Bulldogs won their third straight title on Saturday afternoon, 42-20 over the Dakota Valley Panthers.
On Thursday, the Colman-Egan Hawks topped Sully Buttes for a second straight championship 42-28.
One other team is also along SD-34, and that is the Pierre Governors, who beat Harrisburg in the Class 11AA title game.
No other champions are remotely close to SD-34 - the Britton-Hecla Braves (9A), Gregory Gorillas (9AA), Sioux Falls Christian Chargers (11B) and Sioux Falls Washington Warriors (11AAA).
The SD-34 corridor could be the big winner in the State Volleyball Tournament this weekend as both Madison and Chester will be vying for state titles at Rapid City.
