Book Description

The purpose of this project is to maintain a safe and efficient flow of traffic over the Broadway Viaduct by providing a facility that meets Iowa DOT's current design standards for a principal arterial highway. The Broadway Viaduct is part of U.S. 6 connecting Council Bluffs, Iowa, and Omaha, Nebraska, and needs to be replaced to maintain the connectivity between the two cities. The project is located within the City of Council Bluffs in Pottawattamie County, Iowa. This Environmental Assessment evaluates alternatives for improvements to the existing viaduct and replacing the viaduct, with viaduct replacement identified as the preferred alternative.
