History

SH 170 was originally designated on August 3, 1932, as a connector route from the Oklahoma border west to US 60 and US 87 near Canadian.[2] This route was redesignated as SH 33 on October 26, 1954 to coincide with OK 33, with which it connects.[1][3] The current SH 170 was designated in 1988.

Construction of an interchange at SH 114 began in 2016.[4]

Proposed tollway

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 (SH 199), but it didn't occur.[5]

TxDOT and the NTTA held a public hearing in Roanoke about the proposed toll road on February 26, 2015. The tollway is proposed to have six main lanes.[6]
