Engineers are working night and day in the Northern Ontario cold to try to make the fractured Nipigon River Bridge whole again. The excellent CBC report here describes a series of bolts snapping off like so many pretzels. This caused the road bed to leap upward on tension from the cable suspension system. What strength was called for in these bolts and by what engineering firm? The questions abound and the implications are said to range from economic to political, to social and even international. This bridge along the Trans-Canada Highway in northwestern Ontario was hailed as a “monumental” achievement — part of the largest infrastructure investment in the province’s history. “This is obviously a national issue. This area has been identified as being a vulnerable part of the Canadian transportation sector,” Nipigon Mayor Richard Harvey said Monday.
