Historic SH 9

State Highway 9 or SH 9 was one of the original twenty six state highways proposed in 1917, overlaid on top of the Puget Sound-Gulf Highway. In 1919 the routing follows the present day U.S. Highway 87 from Amarillo, through Canyon, Plainview, Lubbock, Big Spring, San Angelo, Brady, Mason, Fredericksburg, into San Antonio. From San Antonio, it follows U.S. Highway 181 from San Antonio, to Sinton and terminated in Corpus Christi.

In 1919 the direct segment between San Angelo and Brady had not yet been built, so SH 9 was rerouted through Paint Rock for a short time (The segment would be completed by 1922). Much like other highways at the time, multiple alternate routings has been created using the same number, and SH 9 was no exception. From San Antonio, the second route left the city south via Pleasanton Road, merging with present day U.S. Highway 281 from Las Gallinas through Pleasanton splitting off onto present day Interstate 37 into Oakville. It continued west on SH 234 into Odem, and south on United States Highway 77 back to I-37 to its terminus in Corpus Christi.

Historic SH 9A

By 1922 a third routing, signed as SH 9A was created alongside the previous two, overrunning the ambitious SH 12 route from Skidmore to Alice, and continuing south to its terminus in Pharr.

In 1926, U.S. Highway 385 (Later US 87) was overlaid on the original routing from Amarillo to San Antonio. From there, the original routing was resigned as SH 16 and had U.S. Highway 181 overlaid on top of that. The second routing retained the SH 9 designation, continuing the numbering into Corpus Christi that way. The third routing was given its SH 12 assignment back from Skidmore to Alice, assigned SH 66 from Alice to Pharr, and both segments were overlaid with US 96 (Later SH 359 and US 281). In 1933, an extension to SH 9 was being built from Amarillo to Stratford into Oklahoma. This would eventually be overlaid with U.S. Highway 287.

By 1939 most of SH 9 was cancelled, leaving only the Three Rivers-Corpus Christi segment to the old highway. With the completion of I-37 in 1971, SH 9 was cancelled, and has never been reassigned.
