Major Infrastructure Project to Replace South Grimmell Road Bridge in Jefferson

Jefferson, Ia. – Greene County and the City of Jefferson are partnering to replace the aging bridge on South Grimmell Road. The South Grimmell Road bridge has been identified as a high-priority replacement project due to its age and condition. This $2.1 million project is funded by a grant from the Iowa Department of Transportation and Federal Bridge Replacement funds from Greene County.

The general contractor for this project is Godbersen-Smith Construction of Ida Grove, Iowa. They will begin work the week of August 19th and construction will take approximately one year. The bridge will be closed during this time with a detour in place.

The project will involve the complete demolition of the existing bridge structure and the construction of a new, modern bridge designed to handle current and future traffic demands. The new bridge will feature enhanced safety measures, including improved guardrails, widened lanes, and upgraded load-bearing capacity to accommodate heavier vehicles and increased traffic volume.

During construction, South Grimmell Road will be closed to through traffic at the bridge site. A clearly marked detour route has been established, and residents are encouraged to plan accordingly for any potential delays. The marked detour route takes traffic on Westwood Drive / 237th Street, K Avenue, and County Road P18. See the attached map.

Community Impact

The replacement of the South Grimmell Road bridge is a significant investment in Jefferson and Greene County’s infrastructure and will have a positive long-term impact on the community. While there may be temporary inconveniences during construction, the new bridge will provide safer and more efficient travel for all residents and visitors.
