Proposed state highway in Texas, U.S.

State Highway 312 (SH 312) is a proposed state highway from US Highway 90 Alternate (Alt. US 90) just west of SH 6 south to Interstate 69/U.S. Highway 59 (I-69/US 59). The highway was originally designated in 1986 as SH 362, and was renumbered as SH 312 in 1987. As of 2020^[update], the highway has yet to be built.

The original SH 312 was designated on March 21, 1939, from Karnes City southwest to the Atascosa–Karnes county line.^[2] On September 26, 1939, this became part of SH 80.
