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

History

[edit]

Previous route

[edit]

A previous route numbered SH 170 was designated on August 3, 1932, as a connector route from the Oklahoma state line west to US 60 and US 83 near Canadian.[2] This route was renumbered SH 33 on October 26, 1954, to coincide with OK 33, with which it connects.[1][3]

Current route

[edit]

The current SH 170 was designated in 1988.[1]

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

TxDOT and the NTTA held a public hearing in Roanoke about the proposed toll road on February 26, 2015. The tollway was proposed to have six main lanes.[5] The main lanes between I-35W and SH 114 opened to traffic on March 18, 2024.[6]

Proposed Tollway

[edit]

The North Texas Tollway Authority (NTTA) 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 did not occur.[7]
