On July 2, 1932, SH 146 extended north to Dayton.^[2] On August 3, 1932, SH 146 extended north to Cleveland.^[3] On September 22, 1932, this extension was canceled, and SH 146 was instead extended north to Livingston, replacing SH 132, as construction had already started.^[4] On December 16, 1967, SH 146 was relocated east of Liberty. On February 21, 1984, SH 146 extended south from SH 3 to I‑45. On March 28, 1996, SH 146 was relocated in Baytown.
