A new bridge spans the Embarras River on the site where the original Jackson Covered Bridge was built 177 years earlier. It re-creates the original covered timber bridge that once stood here as part of the historic Cumberland "National" Road while being designed to carry modern vehicles, including tractor-trailer semi trucks. The 200-foot single-span structure is reported to be the longest covered timber bridge in the U.S. without a posted restriction. Its scale is reflected in two abutment foundations using more than 1,000 cubic yards of concrete, weighing over 2,000 tons, enough for the foundations of about forty normal 2,000-square-foot homes; more than 250,000 board feet of heavy timbers, weighing 194 tons, enough for about thirty normal 2,000-square-foot single-story homes; and about 40 tons of steel bolts and plates to connect the timber structure.
