[edit] History
[edit] Current Route
The current SH 20 was created in 1969 when the routing of US 80 was realigned with Interstate 10 in this area. This stretch of highway had been part of SH 1, the Texarkana-Dallas-Fort Worth-El Paso highway prior to the creation of US 80. In 1917 the current route of SH 20 was mapped as the concurrency of SH 1 and SH 12 (part of the Jefferson Davis Memorial Highway and also called the Orange-El Paso Highway).
[edit] Previous Routes
SH 20 was one of the original Texas state highways planned in 1917 from Mason through Austin to Houston. In 1919, alternate route SH 20A was routed due west from Austin to Fredericksburg, with a planned extension farther west to Segovia. By 1933, the section from Austin to Mason had been renumbered as part of SH 29, with SH 20 rerouted over SH 20A. In 1935, a realigned US 290 had shortened SH 20 again, now only a stretch from Austin to near Paige. From 1938 to 1951, SH 20 went from Austin through Elgin and ended near Paige. After 1947, US 290 was shifted north (its former route becoming SH 71) to a straightened route parallel to SH 20. The two routes apparently existed side-by-side for several years until when, in 1951, SH 20 was deleted. As of 2005, portions of the original SH 20 are still open to traffic in Bastrop County. The portion from SL 223 in McDade to SS 186 in Paige are signed as "Old Highway 20".
