State Highway 146, or SH 146, is a north–south highway in southeastern Texas beginning in Livingston, starting at US 59 (Future I-69) and proceeds south to Liberty, where it meets US 90. It continues in Dayton at US 90 and proceeds south through Baytown, terminating at Interstate 45 near La Marque and Texas City. In the interest of encouraging use of the Grand Parkway (toll road), which runs roughly parallel to SH-146 to the south of I-10, the State of Texas has removed SH 146 signs from Exit 798 of I-10 in the Westbound direction.^[2]

The Fred Hartman Bridge over the Houston Ship Channel carries SH 146 traffic.
