North Avenue Bridge


Looking South from BH49963 CBQ Fox River Bridge

One continuous bridge but it looks like 2 from the other side because of the entrance onto Hurds Island

The original six span concrete arch structure which carried North Avenue over the Fox River in Aurora, Illinois was constructed in the 1920ís. In 2000, the task of investigating the structural and functional condition of the existing structure was undertaken. The outcome of the investigation indicated the superstructure and portions of the substructure were in need of replacement to carry current design loads. The existing concrete arches and underlying arch foundations would be allowed to remain with limited structural repairs. Because of the historical nature of the structure, the task undertaken by the design team was to design a new structure that would recreate the original look and character of the nearly 80-year-old bridge. The original 1920ís era plans were found and used as the starting point. The original ornamental concrete railings along with the ornamental lights were recreated on the new structure. Likewise, identical spandrel arch beam size and spacing, and column size and spacing, were used in order to obtain historical agency concurrence on the project. Precast elements were used for the railing, transverse beams, deck planks, and other members in order to reduce the amount of falsework required and speed the construction of the project.

Finally got some better pics. The bridge sits on the tip of Hurds Island so it appears to be 2 bridges from the island side. The entrance down on to the island has been closed for construction. Much better view from there.

I agree! This bridge is strikingly similar to the Anoka-Champlin Bridge in Hennepin County, MN:


Not only do they look very similar in design, they both went through strikingly similar overhauls, the MN bridge in 1998. It, too, retained its arches and had most other components fabricated with historic sensitivity intact.

This is what a new bridge SHOULD look like!
