IA 32 (Northwest Arterial) Capacity Improvements

The IA 32 capacity improvement project went beyond the expansion of the roadway to include the integration of new traffic technology, including a fiber optic system, pan-tilt-zoom cameras, stop bar cameras, microwave detection and connection to the traffic control center located in city hall.

The roadway improvements included the realignment and addition of left and right turn lanes at both Asbury Road and Pennsylvania Avenue intersection.

The design process included extensive coordination with the IDOT to verify the acceptability of the design, conformance with the funding agreements, and required permitting. IIW provided both design and construction engineering services.
