Yellow brick road
The actual road is believed to be one in Peekskill, New York, where L. Frank Baum attended Peekskill Military Academy. According to a local legend, the Yellow Brick Road was derived from a road paved with yellow bricks near Holland, Michigan, where Baum spent summers. Ithaca, New York, also makes a claim for being Frank Baum's inspiration. He opened a road tour of his musical, The Maid of Arran, in Ithaca, and he met his future wife Maud Gage Baum while she was attending Cornell University. At the time, yellow bricks paved local roads. Yellow brick roads can also be found in Aberdeen, South Dakota; Albany, New York; Rossville (Baltimore County), Maryland; Montclair, New Jersey (Parkhurst Place and Afterglow Way); Bronxville, New York (on Prescott and Valley roads); Chicago, Illinois; Liberal, Kansas; Sedan, Kansas and Chittenango, New York, as well as a school in Abington, Pennsylvania, and abroad in Sofia, Bulgaria.
Kansas Turnpike
Because the Kansas Turnpike was built before the Interstate Highway System, it is not engineered to current Interstate Highway standards; however, as with all other toll roads that predated the Interstate Highway System, the highway is grandfathered from Interstate standards. The turnpike was originally constructed with lanes only wide. Notably, the turnpike was built without a median. When it opened, the central reservation was a depressed median. Starting in 1985, Jersey barriers were installed along its entire length.
