BB&A provided design/build engineering services for this new 10-span arch bridge over the Fox River. Originally opened in 1958, the original bridge carried two lanes of traffic in each direction. The new structure has been widened to meet the increased capacity.

In order to replicate the design of the original bridge, the 1,345 foot long structure was made of precast concrete, featuring a series of five spans out of ten total spans. The arch rib design using precast reinforced, rather than post-tensioned concrete added value to the project and assured that our design resulted in the lowest bid while meeting the aesthetic and environmental requirements of the stakeholders.

Given the location and complexity, this project required a great deal of coordination with a number of different stakeholders, including the Illinois Tollway, Village of North Aurora, City of Aurora, BNSF Railroad, Illinois Commerce Commission, Fox Valley Park District, Fox Metro Sanitary District, Army Corps of Engineers and several utility companies. In addition to Bridge plans, BB&A performed hydraulic studies of the Fox River, utility relocation, and mainline widening and ramp relocations.
