Tennessee State Route 177 is a secondary state highway in Shelby County, Tennessee. The majority of the route is known as Germantown Road and Germantown Parkway.
The route starts in southeast Memphis, Tennessee on Winchester Road near Tennessee State Route 385 (Bill Morris Parkway) with a speed limit of 40 MPH. From there it runs north through the city of Germantown with a speed limit of 35 until it intersects with U.S. Route 72/State Route 57 where the speed limit rises to 40. It then crosses the Wolf River where the speed limit rises to 45 and passes back into Memphis through the Cordova community. SR 177 later intersects Interstate 40 near the Wolfchase Galleria. SR 177 crosses U.S. 64/State Route 15 (Stage Road) in Bartlett, Tennessee, before terminating as a state route at U.S. 70/U.S. 79/State Route 1. Germantown Road continues north until Old Brownsville Road near the Brunswick community.
Beginning at the U.S. 72/State Route 57 intersection, 177 turns from a two-lane road into a six-lane highway, and continues in this form through to its north terminus, and from the Wolf River bridge until the I-40 junction, the road is six-lane and has 10-foot-wide (3.0 m) paved outside shoulders on both sides, which only occasionally give way to a fourth lane or a right-turn lane. It also has a grassed median from the Wolf River to US 64. North of I-40 until Hwy 64, the road has 4 lanes in each direction. North of Hwy 64 until the route terminates, the road has 3 lanes in each direction.
Prior to 1990, SR 177 was two lanes throughout its length. After 1990, the route was expanded into its current form from U.S. 72 – SR 57 to the I-40 – U.S. 64 area. In the late 1990's, it was expanded to its current form between U.S. 64 to U.S. 70/79. Germantown Parkway, as it is known locally, has seen significant commercial and residential development starting in the 1990s, including the establishment of restaurants, hotels, planned communities, and the Wolfchase Galleria. North of U.S. 64, however, little new development has taken place besides the addition of a few residential subdivisions, a school, and a Walgreen's near U.S. 70/79.
The speed limit between the Wolf River I-40 was 50 miles per hour until 2014 when the city of Memphis lowered it to 45 MPH, possibly due to increasing traffic counts.
Construction to widen a portion of SR 177 from Stout Road to Crestridge Road to 5 lanes is underway. Also, the portion of SR 177 that overlaps Poplar Avenue was modified in 2013 to allow for two left turn lanes at both the Poplar/West St and Poplar/Germantown Pkwy intersections. This is to complement the new two left turn lanes at Germantown and Farmington.
The entire route is in Shelby County.
