Project Overview 

The Iowa Department of Transportation, in coordination with the City of Sioux City and the FHWA, is planning a multiyear reconstruction project to improve Gordon Drive, Lewis Boulevard, Cunningham Drive, and the Bacon Creek Conduit.

The Gordon Drive Viaduct and Bacon Creek Conduit project in Sioux City aims to improve safety and mobility for everyone traveling along Gordon Drive—from Virginia Street to Rustin Street—including drivers, pedestrians, and bicyclists. The project will address structural issues with the existing viaduct and conduit.

Key concerns include:

• Aging infrastructure with structural deficiencies.
• Roadway design that does not meet current standards.
• Inadequate lane widths and cross sections.

By reconstructing these key corridors, the Iowa DOT will enhance traffic flow, reduce safety risks, and support long-term transportation needs in the area.
