State Route 160 (Sedgwick Road) is an important east-west connection that provides primary access between State Route 16 and the Southworth Ferry. SR 160 also serves local drivers, and regional commuters. The existing highway has narrow shoulders and numerous intersecting streets and driveways. A two-way stop sign exists currently at the intersection of SR 160 and Long Lake Road SE.
The study began in the fall of 2016 and was completed in the spring of 2018.
