摘要：	This article discusses the extreme measures being taken by the Iowa Department of Transportation and its design and construction partners to protect the environment and fauna, including bald eagles, during the relocation of a 40-mile segment of U.S. Route 20. This roadway corridor, located in Hardin and Grundy counties in north-central Iowa, is characterized as a rural agricultural area with several small towns and containing an environmentally sensitive greenbelt area in the Iowa River valley. Finding a way to build a modern, safe, and efficient highway facility through such an area, while minimizing construction impacts and intrusion to the Iowa River crossing, has proven to be very challenging. Some of the major issues of environmental impact addressed by this project are listed, the project partners are mentioned, the parameters of the U.S. Route 20 Bridge being built over the Iowa River are provided, and construction challenges are outlined.
