1887-1943 US-20 Wagon or High Bridge over Mississippi River at Dubuque, IA

(Bridge Hunter; no John A. Weeks III; Satellite, it was 75' downstream from the railroad bridge)

"It is the longest crossing of its kind in the West and exclusively highway in character." When the swing span of the IC+CGW railroad bridge is opened, it swings under the cantilever span of the high bridge. [Bridge Hunter] This bridge was replaced in 1943 by the Julien Dubuque Bridge, which is further downstream.

C. L. Strobel was chosen to design a pontoon bridge at this location. But he suggested a high bridge that would not need a movable span. So the plan to build a pontoon bridge changed to a plan to build a high bridge. I've seen the date of 1886 for this bridge, but that is when the money was raised. The first teams crossed the bridge on Nov 25, 1887.

Most of the old aerials of Illinois were taken in the late 1930s so I was surprised to see the Julien Bridge instead of the Wagon Bridge. Then I noticed that the date for this photo was 1947.
