It then crosses the Wolf River where the speed limit rises to 45 and passes back into Memphis through the Cordova community.

Beginning at the US 72/SR 57 intersection, SR 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.

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.

The speed limit between the Wolf River and 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.

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.
