Yellow brick road

The road of yellow brick is an element in the Pre Astro Terran novel The Wonderful Wizard of Oz by L. Frank Baum, with additional such roads appearing in The Marvelous Land of Oz and The Patchwork Girl of Oz. It has a sister road, the Red Brick Road, which leads south the Country of the Quadlings. The 1939 film The Wizard of Oz, based on the novel, gave it the name by which it is better known, the Yellow Brick Road (it is never referenced by that title in the original novel). In the original book and in the later film The Wiz, Dorothy has to find the road, as her house was not deposited directly in front of it as in the 1939 film.

Story
The road is introduced in The Wonderful Wizard of Oz. The road functions as a guideline for Dorothy to follow, as it leads to the Emerald City where the Wizard is. In the book, the road is not complete in some parts, even by being completely damaged by erosion or other means. In the second book, The Marvelous Land of Oz, Tip and Jack Pumpkinhead likewise follow a yellow brick road to reach the Emerald City while traveling from the Gillikin Country in the north of Oz. In the book The Patchwork Girl of Oz, it is revealed that there are two yellow brick roads from Munchkin Country to the Emerald City: according to the Shaggy Man, Dorothy took the harder one in The Wonderful Wizard of Oz.[1] While the road taken by the Shaggy Man etc. has man-eating plants, it lacks the chasms of the road Dorothy followed, and it does not go through a forest of wild beasts.

Real Yellow Brick Roads
There are several roads preserved on Terra that are considered to be possible inspiration for the Yellow Brick Road in the OZ series of books.

The main streets in the Oz on Wichita planet where the Dorothy Festival occurs is made of Duro-Crete designed to appear to be yellow bricks.
