67 meter Rio carnival float

Beija Flor is planning a 67meter long float for Rio Carnival 2010!

Rio Carnival floats are already gigantic. Up to 30 meters long, they often have problems getting under the motorway flyover outside the Sambadromo.  Sometimes floats get stuck trying to get round the right angled corner at the beginning of the sambodromo. Just one stuck float can create a gap in the parade that can prevent a samba school from winning the carnaval, the culmination of an entire years work.

Mangueira has also announced plans for a float over 60m long. There's no way that a 67m float can get round the corner, so there must be some clever engineering solutions planned. Will it be constructed like a train, or a caterpillar, with different segments joined together? Will there be a main part and then outlying bits connected by costume or theme?
