Segment 3 of the I-75 Modernization Project involved designing and reconstructing 1.5 miles of rural freeway and 4 miles of urban depressed freeway, including service drives, ramps, and bridges. A significant feature of this segment was the construction of a new 14.5 ft. diameter, 4-mile-long storage, and drainage tunnel with an accompanying pump station.
