Use Morph (and either Spring Ball, Bombs, or Power Bombs) to navigate the space above the first set of Speed blocks. Either kill or carefully jump over the Pirates; their hitbox is much smaller when they are not looking around. Then use a flash suit to shinespark through the second set of Speed blocks.

Dev note: This strat is only useful with heat protection; otherwise it would be better to spark from left of the bridge.
