How many roses are used in the Rose Bowl Parade?

The Tournament of Roses Parade has followed the same route for many decades. It starts by going north on South Orange Grove Boulevard, beginning at Ellis Street. On parade morning, it proceeds east on Colorado Boulevard (Pasadena's main thoroughfare and a segment of the former US-66), to Sierra Madre Boulevard. Turning north on Sierra Madre, it ends at Paloma Street. On going North, the floats must travel under the Sierra Madre / I-210 freeway overpass, requiring them to collapse to meet a specific height requirement. In total, this route is 5½ miles (9 km) long; the assembled bands, horse units, and floats take approximately 2 1/2 hours to pass by.
