The last of 484 concrete segments has been placed at the 457m-long Four Bears Bridge across Lake Sakakawea in North Dakota. The precast concrete segmental structure, designed by Figg Engineering Group, has been constructed by Fru-Con Construction using the balanced cantilever method. The US$55.4 million scheme is the state's largest ever bridge project and replaces an existing bridge 30m to the south which will be demolished once the new crossing is in use.
