这座连接美加的新大桥引发全球关注，为何被称为汽车供应链“黄金纽带”？

Core Viewpoint - The Gordie Howe Bridge, a new infrastructure project connecting Detroit, USA, and Windsor, Canada, is set to enhance the efficiency of the North American automotive supply chain, but its opening is currently under scrutiny due to political tensions [2][8]. Group 1: Importance of the Bridge - The Gordie Howe Bridge, funded by Canada at approximately $4.6 billion, is crucial for improving logistics efficiency in the cross-border automotive industry, serving as a "golden link" in the North American automotive supply chain [2][3]. - The bridge will significantly reduce border crossing times, which currently rely on the Ambassador Bridge, known for severe congestion, potentially saving up to $2.3 billion in costs for drivers and the transportation industry over the next 30 years [3][4]. Group 2: Impact on the Automotive Industry - The bridge is expected to facilitate smoother and faster transportation of automotive parts and vehicles between the U.S. and Canada, which is vital for maintaining the efficiency of production lines in the automotive sector [4][5]. - The Detroit-Windsor corridor is one of the busiest freight routes in North America, with trade volumes reaching $126 billion in 2023, underscoring the bridge's role in the automotive supply chain [5]. Group 3: Risks of Non-Operation - If the Gordie Howe Bridge does not open, it could disrupt the automotive supply chain, particularly affecting Michigan's automotive manufacturing, leading to delays in parts transportation and potential production halts [9]. - The inability to utilize the new bridge could exacerbate job losses in Michigan's automotive sector, where 2,400 jobs have already been lost, and increase logistics costs, thereby diminishing market competitiveness [9][10]. - The bridge is designed to replace the outdated Ambassador Bridge, with an expected 30% improvement in cross-border freight efficiency and a capacity of 15 million vehicles annually; failure to open would hinder Michigan's automotive industry from benefiting from these advancements [9].
