Three bridge projects will close roads across the county for up to a week later this summer.

The county is removing and rebuilding the bridges on 600th Avenue in Red Rock Township, 665th Avenue in Adams Township and 140th Street in Lodi Township. Public Works Director Mike Hanson said the projects will close the roads at the bridge sites for up to a week and will likely happen in July.

Asbestos testing shouldn’t slow work

Crews working to reconstruct the Roosevelt Bridge are testing a portion of the bridge for asbestos, but Public Works Director Mike Hanson said it’s nothing out of the ordinary and shouldn’t slow work to restore the historic structure.

Hanson said testing for asbestos and other waste is done on all bridges. The section in question wasn’t tested earlier because it is underground.

The county is in the second phase of the Roosevelt Bridge historical renovation. This summer’s work will cost about $2.5 million, but most is being funded through state and federal grants. When the project is finished, the bridge will have new sidewalks on both sides.

Previous estimates call for the total project, which closed the bridge much of last summer, to cost about $3.6 million, but only about $800,000 would be local dollars. About $2.9 would come from federal dollars or state bonds.

The bridge spans the Cedar River on Fourth Street Southeast between Fourth Avenue and Sixth Avenue.
