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
The Kansas Turnpike then leaves Lawrence and bends to the northeast before leaving Douglas County and entering Leavenworth. It overpasses Mud Creek before passing under K-32. Northeast of here at mile 209, the Lawrence Service Area is in the median. Afterward, the turnpike has a diamond interchange with 222nd Street, which is signed as Leavenworth County Road 1, at Exit 212 (Tonganoxie/Eudora). The highway then travels northeast and passes through it eastern terminal toll booth. This is the final toll booth on the route travelling east and all vehicles must pay their final toll before continuing. The turnpike then enters Bonner Springs. It crosses Wolf Creek before leaving Leavenworth County and entering Wyandotte County. In Bonner Springs, the turnpike intersects K-7, westbound US-24, westbound US-40, and the southern terminus of US-73 at Exit 224 (Bonner Springs, formerly Exit 223) with a trumpet interchange. This is the first free exit eastbound. The mileposts on the route switch to match those of I-70 after this interchange.
