The following photo raised the question of why does a stone viaduct just end? The short answer is that the swing span was removed after the Superior Viaduct was replaced by the Detroit-Superior High Level Bridge. As you can image, the rest of this page is the long answer.
The first high-level bridge across the Cuyahoga Valley was started in March 1875 and opened in Dec. 1878. Because it had a swing span, road traffic would still be stopped by some river traffic. But there would be far fewer stoppages than suffered by the low-level bridges. Plus it saved braking your buggy or wagon while going down into the valley and then the horse having to pull it back out of the valley on the other side. [

[Note the abundance of streetcars and the scarcity of cars in 1912. I found one car and a couple of trucks.] |

In 1917 a higher level bridge was built so that no river traffic would impact the traffic on the bridge. The approaches are reinforced concrete arches and the 590' main span over the river is, obviously, a steel arch. The upper level was designed for four lanes of traffic and the lower level held six streetcar tracks. The streetcar deck was abandoned in 1955. The swing span was removed from the Superior Viaduct in 1923.
Please see the links at the top for more information about the 1917 bridge.
This "hold Ctrl and move the mouse" Google View shows that several of the old stone arches still exist on the western side. It also shows the bridge that replaced it in the background.
It is interesting that the smaller arches under the upper deck of the eastern approach of the 1917 bridge don't appear in the above view. I captured this street view to confirm that the missing inter-deck arches are because I was pushing Google's 3D algorithm really hard to get a view of the stone arches.
Some of the arches of the 1878 bridge were removed in 1938.
