Route description

Existing entirely within Seneca County's Adams Township, SR 778 has an AADT of 1150. The route's short journey begins at the intersection of SR 101 and County Road 43 (CR 43), and travels north, taking over for the county road. The two-lane connector route travels north, arriving at its endpoint at the intersection of SR 19 and CR 44. As SR 778 enters the intersection from the south, SR 19 forms the northern and eastern legs, and CR 44 uses the western approach to the intersection.
