The original plan was to replace the worst sections of the old concrete with new concrete, then apply an asphalt overlay over the remaining sections of the street.
Late into the project, a federal inspector required that all of the old concrete be replaced either with full-depth asphalt or full-depth concrete.
The Hillsboro City Council chose the more expensive option, full-depth concrete, because of its long-term durability. The change cost the city $125,000.
In his introdcutory remarks at the ribbon-cutting, City Adminstrator Larry Paine said Hillsboro was able to achieve a $600,000 project with a local investment of only $125,000.
During construction, traffic entering Hillsboro via Ash Street, the main entry point off U.S. Highway 56, was detoured through the former AMPI property and down Main Street to Grand Avenue, before returning to Ash Street from there.
