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.
Missouri Route 48
The Route 48 designation first appeared on state maps in 1926, as an unimproved road starting from US 71 and ending at Route 4 in King City. A bridge at the One Hundred and Two River that carried the route was built in 1929, with a cost of $49,087. A large section of Route 4 was designated as US 169 in 1931, including Route 48's eastern terminus, and the Route 48 sections in Gentry County and from US 71 to Rosendale in Andrew Country were improved and had new gravel laid down; the paving costs were $101,176 () and $150,282 () respectively. About two years later, gravel was laid down from Whitesville to the Andrew–Gentry county line. The remaining section from Rosendale to Whitesville was laid down with gravel by 1936. The first asphalt paving on the route began in 1938, where the Gentry County section was paved first, with a cost of $38,861 (). The rest of the route was paved in asphalt four years later. Route 48 was resurfaced and shoulders were reshaped in 1974 from Rosendale to King City, which cost $435,278.46 (). The bridge at the One Hundred and Two River was replaced by a new bridge in October 2014.
