State Route 171 (SR 171) runs south - north through Davidson and Wilson counties in the state of Tennessee. It connects Interstate 24 to U.S. Route 70.
SR 171 begins in Davidson County in Antioch at an interchange with I-24 (Exit 62) in a large industrial park. It goes north as a 2-lane highway to leave the industrial park and pass through residential (with light commercial) areas to have an intersection with US 41/US 70S/SR 1 (Murfreesboro Pike), where it passes by the former site of Starwood Amphitheatre, which was the Nashville area's premier outdoor music venue until it closed following the 2006 season, before it crosses Percy Priest Lake (Stones River). Once across the water, SR 171 travels through Long Hunter State Park for a short distance, before entering another residential area and crossing into Wilson County.
SR 171 continues north and passes through Rural Hill before entering Mount Juliet at its intersection with SR 265 (Central Pike). The highway almost immediately enters commercial areas and winds to a 4-lane undivided highway, and has an interchange with I-40 (Exit 226) soon afterwards. SR 171 continues north through some more residential areas before entering another commercial area, where it comes to an end at an intersection with US 70/SR 24 (Lebanon Road).Finally, the road ends in a dense commercial area, as it travels through the city of Mt. Juliet.
