Whereas, On November 3, 1930, the Detroit-Windsor Tunnel officially opened to traffic following a historic telegraphic signal from President Herbert Hoover, becoming the first and only underwater vehicular tunnel in the world to connect two sovereign nations; and
Whereas, Conceived through cross-border vision and cooperation beginning in 1919 between Detroit Mayor James Couzens and Windsor Mayor Edward Blake Winter, the tunnel was completed ahead of schedule and under budget, marking one of the great engineering achievements of the 20th century; and
Whereas, For 95 years the tunnel has served as a vital economic and cultural artery, linking Downtown Detroit, Michigan and Downtown Windsor, Ontario, and facilitating the movement of people, goods, and services between our two nations; and
Whereas, More than 3.7 million vehicles traveled through the tunnel in 2023 alone, including over 11,600 passenger and nearly 240 commercial vehicles daily—supporting a regional supply chain for auto parts, steel, agriculture, and medical services; and
Whereas, The tunnel supports over 325 jobs in Detroit and contributes more than $595 million annually in economic impact to the City of Detroit, helping to fuel tourism, workforce mobility, and binational commerce; and
Whereas, The tunnel stands as a model of cross-border collaboration and a symbol of the enduring partnership between Michigan and Ontario; now, therefore, be it
Resolved by the House of Representatives, That the members of this legislative body declare October 23, 2025, as Detroit-Windsor Tunnel Day in the state of Michigan. We recognize the importance of this unique infrastructure asset as it celebrates its 95th anniversary and looks ahead to its continued role in linking our communities and driving our shared future.
