History
SR 203 was established in 1923. The highway was originally routed along its current alignment between its present southern terminus, at the time designated as SR 47, and its junction with what is now SR 739, but in 1923 known as SR 38.[1][2] In 1938, SR 203 was extended north to its present terminus at what is now SR 309, but at the time a part of the now-defunct U.S. Route 30S (US 30S).[6][7]
