The GREENBELT The BRIDGE The ENVIRONMENT The HIGHWAY PROJECT TEAM

An improved US 20 across Iowa has been in the works since the mid-1960's. With improvements through Grundy and Hardin Counties complete, a four-lane US 20 now stretches more than halfway across the state, from the Mississippi River to Fort Dodge.

This vital link to our future passes through a treasured piece of yesterday. The Iowa River Greenbelt is a rare, remaining fragment of what our state used to be, a strip of old-growth woodland that has survived the age of agriculture. The Greenbelt is secluded and peaceful, a haven for bald eagles and a heaven for canoeists; it is an area of great historic, ecological and archaeological significance.

The US 20 bridge treads gently through the Greenbelt. To minimize the impact of construction, engineers used a unique bridge-building technique not normally used in the United States, a process called Launching. The bridge's visual and physical effects on the Greenbelt are expected to be minimal. The bridge design and the construction plans were developed following years of intensive study into the area's biology and cultural resources.

The US 20 Iowa River Bridge provides an avenue to Iowa's future, while respecting its natural past.
