How does king use figurative language to express the idea that, though the journey is long and difficult, the civil rights movement will eventually be victorious

King’s exquisitely powerful use of metaphors and his masterful employment of figurative speech, were the centerpiece of his rhetoric. He'd often compare two or more, sometimes vastly different things that were linked at least by one attribute to produce an even greater effect on the listener.

One famous example I would note:

His reference to the Emancipation Proclamation as “a great beacon of hope” in relation to the phrase “a joyous daybreak”. Here, he was effectively transmiting the point that as a beacon or  daybreak can illuminate hope, the Emancipation Proclamation would bring enlightenment and joy to all suffering slaves.

To address this question specifically he's comparing the journey to both a "tortuous road" and "a super highway of justice", at the same time. By doing so, King makes us acknowledge the hardships to come while immediately turning our focus up to the heights of the reward in the form of justice.

Hope this helps!

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
