The CUYAHOGA COUNTY CENTENNIAL was observed with a week-long celebration, 10-15 Oct. 1910. Daily features of the centennial celebration included afternoon and evening band concerts on PUBLIC SQUARE, a carnival and sideshows on the Mall, and an Indian village of 3 teepees and 14 Chippewas brought in from an Indian reservation in Michigan and erected on the Square. Monday's major event was the dedication of the new Harvard-Denison Bridge by the Cuyahoga County commissioners. On Tuesday, 300,000 spectators viewed a parade of floral-decorated automobiles traveling from WADE PARK along Euclid Ave. and proceeding across the SUPERIOR VIADUCT and along Detroit Ave. to the western end of LAKEWOOD, where dedication ceremonies were held by the county commissioners for the new Rocky River Bridge. Wednesday activities, held under the auspices of Cleveland's Italian-American societies, celebrated the anniversary of Christopher Columbus's discovery of the Americas. Thursday was designated as "Cleveland Day." Open houses were held at all Cleveland firehouses, and the centennial anniversary fireworks display was held on the lakefront. Special seating arrangements for 10,000 were set up along the embankment overlooking the lakefront airfield as aviators Glenn Curtiss, Augustus Post, Bud Mars, Chas. Willard, J. D. McCurdy, and N. C. Adosides performed on Thursday for the first of a 2-day aerial show. Saturday's closing festivities included a powerboat regatta and races at EDGEWATER PARK and the biggest parade in Cleveland's history, featuring Cleveland's military and fraternal orders and 26 marching bands.
