The DOT announced April 30 that Flatiron-Lane would build the new I-85 bridge, a replacement bridge for the U.S. 29-70 northbound traffic, bridges taking I-85 over the railroad's main line and a spur line, and redesign one interchange and remove another, in addition to widening and relocating 3 miles of I-85, for a total cost of $136 million, $44 million less than expected.
