Is this even possible? animation

hi, ive done an illustration showing a cross section of a bridge and its flooring peeling up (this is gonna be the animated part)

it would start with the flooring in its correct place then lifting up from the near corner…

how can i put this into flash to animate it?

note: ive used alot of transparacy effects on the illustration which wont open in flash properly…

many thanks
