A Canadian environmental group says studies supporting the proposed Detroit River International Crossing (DRIC) are flawed. DRIC supporters on both sides of the border say a new crossing will create jobs and bolster international trade. The Canadian and Ontario governments strongly support the project, and Governor Snyder recently voiced his approval too. But a Sierra Club of Ontario report says the traffic projections DRIC supporters cite are flawed. They say cross-border traffic has declined for 12 years, and shows no sign of rebounding anytime soon. Sierra Club director Dan McDermott says the DRIC would be a costly boondoggle. “There is simply no demand for DRIC. No cross-border traffic demand that justifies five-plus billions of dollars.” McDermott says he hopes the report will bolster its cases against the DRIC in Canadian courts. Those lawsuits challenge the project’s environmental permits.
