State Highway 170 (SH 170) also known as the Alliance Gateway Freeway, is a Texas state highway in the northern suburbs of Fort Worth. The highway was designated in 1988.

The North Texas Tollway Authority planned to build tolled main lanes by 2015 and will extend the highway west to US 287/US 81, and, eventually, ultimately to extend it to the Jacksboro Highway, but it didn't occur. (SH 199).^[2]

History

SH 170 was originally designated by 1933 as a connector route from the Oklahoma border west to US 60 and US 87 near Canadian. This route was redesignated as SH 33 in 1955 to coincide with OK 33, with which it connects.^[1]
