SH171 begins at an intersection with US84 in Mexia, before quickly intersecting State Highway 14. Leaving the town, SH171 runs northwest to Tehuacana, before running in a more west direction to Coolidge. The highway runs in a northwest direction again, running through the towns of Hubbard and Malone before entering Hillsboro. SH171 runs through the town overlapped with State Highway 22, before running in a mostly north direction towards Cleburne. In Cleburne, SH171 shares an overlap with State Highway 174 through the city. After crossing U.S. Route 67 and the Chisholm Trail Parkway, the highway turns back in a more northwest direction towards Godley and Cresson. After Cresson, SH171 briefly has a run in Hood County before entering Parker County. The highway enters into Weatherford, where it ends in downtown at an intersection with US180.
History
The route was originally designated on August 3, 1932 along the portion between Hillsboro and Coolidge.[2] On July 15, 1935, the section from Coolidge to Hubbard was cancelled (as it was not built yet).[3] On September 22, 1936, this section was restored.[4] On January 18, 1937, the route had been extended to Covington.[5] On March 16, 1937, the section from Hubbard to Munger was cancelled due to a lateral project.[6] This section was restored on October 24, 1938.[7] On October 25, 1938, SH 171 was extended southeast to Mexia along the old route of US 84/SH 7. On September 26, 1939, SH 171 was extended to the northwest significantly, absorbing portions of SH 2A and all of SH 122.
