Route description
Route 177 begins in Rhode Island at an intersection with Route 77 (Main Road) in Tiverton near Nannaquaket Pond. The route progresses northeast as Bulgamarsh Road through a residential neighborhood. After the intersection with Fish Road, Route 177 turns eastward and leaves downtown Tiverton. More woodlands begin to surround the two-lane highway before turning eastward into Bliss Corners, where it curves to the south of Stafford Pond. In downtown Bliss Corners, Route 177 intersects with Route 81 (Stafford/Crandall Roads). After the intersection with Route 81, Route 177 turns eastward one last time out of Bliss Corners and crosses the Massachusetts state line, entering a remote section of the city of Fall River, Massachusetts.

After crossing the state line into Massachusetts, Route 177 becomes known as American Legion Highway and crosses north of several bodies of water through Fall River. After intersecting with Tickle Road, the highway curves to the southeast and into a short stretch of residents through the hamlet of Brownell Corner. After the intersection with Sanford Road, Route 177 curves to the northeast once again. Just northeast of Brownwell Corner, the highway enters a diamond interchange with Route 88 before entering Westport. Through Westport, Route 177 turns northeastward once again, but remains rather wooded until the intersection with Forge Road, where it becomes residential once again. The route intersects with Beeden Road then merges into the right-of-way of U.S. Route 6 in Westport. This serves as the eastern terminus of the Massachusetts segment of Route 177.
