Abstract: The world's largest underwater tunnel was built out of sight and sound of Ft. McHenry. The 4,000 ft tunnel needed to take I-95 from shore to shore had to be extended to 7,200 so the tunnel could curve around the fort and descent 100 ft below the navigation channel. The project set several precedents. For the first time, two sets of sunken tubes were placed, side by side, in the same trench. Also the longest eight-lane tunnel in interstate highway history, it closes up the last major gap in the 85 mile Maryland section of I-95. The $750 million project was completed on schedule and $75 million under budget.
