U.S. President Donald Trump has threatened to block the construction of a new bridge connecting Detroit to Canada. Bloomberg posted on X that this decision came after a meeting between Trump's Commerce Secretary and a billionaire who owns an existing bridge near the proposed site. The billionaire's bridge is located just miles from where the new span is planned, raising questions about potential conflicts of interest. The meeting has sparked discussions about the influence of private interests on public infrastructure projects. The new bridge is intended to improve transportation and trade between the U.S. and Canada, but Trump's opposition could delay its progress. The situation highlights the complexities of balancing economic development with private ownership interests.
