where does the ohio river begin and end
The Ohio River ends at the confluence with the Mississippi River at Cairo, Illinois. This confluence borders Kentucky, Illinois and Missouri. Even though the Ohio River is much wider and carries more water than the Mississippi where they meet, the Ohio is considered the tributary to the Mississippi.
The Ohio River starts in Point State Park which is in Pittsburgh, Pennsylvania. The Ohio River is 981 miles long and flows through many states until reaching the Mississippi River in Illinois. /Society/.../where_does_the_ohio_ri...
