The Ashland Avenue Bridge over North Branch Chicago River is an example of one of Chicago's smoothly curved pony truss bascules. Perhaps the most graceful of the many Chicago bridge forms, the bridge conveys almost a modern and simplistic appearance, while also maintaining the geometric complexity which makes truss bridges so intriguing to the eye. This particular bridge is further embellished by bridge tender towers which include beautiful decorative relief panels with depictions of persons holding various parts of the bridge, such as the trusses, bridge tender builders, gears, etc. This is the only remaining Chicago bascule bridge to display these depictions (A bridge with similar depictions on Ogden Avenue was demolished in 1995), which is clear evidence of the individual significance of this bridge among the many historic bridges within the Chicago bascule bridge group. Scippione Del Campo was the artist and architect who crafted these beautiful panels.
This bridge is the northernmost highway example of the greatest collection of historic bascule bridges on the planet, which is located in the city Chicago and Cook County. The fact that Chicago is a city with such a large, record-breaking number of bascule bridges, and most of them considered historic, is something the city should be truly proud of. For the most part, Chicago has been a model for historic bridge preservation, especially with the bridges in the downtown area. They have chosen to maintain, and rehabilitate as needed, their historic bridges for the continuous heavy traffic one might expect in the nation's third largest city. The fact that so many of these bridges remain functional and historically intact as well sends a message to other cities and even rural locations who claim that historic bridges cannot serve the needs of modern day traffic.
While Chicago is a leader in historic bridge preservation downtown, how do the city's historic bridges fare out away from the core of the city? Their conditions vary widely, some remain in excellent condition, while others show need of rehabilitation. How does the city's commitment to preservation stand outside of the downtown? This remains to be seen for certain, with initial evidence pointing in both directions. Certainly, nearby Cortland Street Bridge displays a commitment to preservation, having been continuously maintained and preserved the past few years. However, it is worth noting that Ashland Avenue Bridge was not always the northernmost historic movable highway bridge in Chicago. Nearby Damen Avenue Bridge to the north was demolished and replaced with a modern through arch that, while more attractive than a normal modern bridge, does not convey Chicago's movable bridge or industrial heritage, and does not blend into the context of Chicago bridges or the canalized river in which they cross. It is impossible to make a connection to Chicago's past, or the canal's past with this new bridge.
Many of the movable bridges on the North Branch and South Branch (Sanitary Canal) of Chicago River are unlike those on the main branch and downtown Chicago. In addition, some of the oldest and most historic bascule bridges are on the North Branch. It is essential that these outlying bridges be preserved alongside the core downtown movable bridges. Moving forward, if Chicago wishes to maintain its image as the worldwide capital of bascule bridges, and if it also wishes to maintain its image as one of this nation's great Historic Bridge Cities alongside cities like Pittsburgh, a preservation plan for its remaining historic bascule bridges should be put in place.
The bridge cost $1,700,000 to construct and more than 10,000 people attending the opening ceremonies. American Bridge Company of New York, New York fabricated the superstructure, while the on-site contractor for the superstructure was Ketler-Elliott Company of Chicago, Illinois. The below photo shows the bridge superstructure completed, although the bridge tender houses remain structural skeletons awaiting their facing.

September 2015 - Fall Bridge Lift Season is Underway. View Schedule.
October 2014 - A visit to Chicago revealed that the Van Buren Street Pedestrian Bridge was not demolished, but instead extensively rehabbed. The railings are new, but replicate the original design. The concrete encasement was removed and not replaced, and instead the exposed riveted steel beams have been painted. The riveted beams look quite nice, and given the condition of the bridge prior to the project this seems like a good outcome. In other news, the rehabilitation and repainting of the La Salle Street Bridge is ongoing, and the project to extend the Chicago Riverwalk under additional bridges on the Main Branch is continuing.
September 2014 - Chicago's dubious distinction of offering numerous boat tours that pass under the bridges but offer narration only of the buildings has ended with the start of a Wendella tour that focuses on bridges! Information is here.
July 29, 2013 - A project study has been initiated for the reconstruction of historic North Lake Shore Drive. This project puts a large number of historic bridges at risk for demolition and replacement. However, it could also be an opportunity to rehabilitate the bridges. Visit the project website.
