House Resolution No. [insert number] proposes to officially designate October 23, 2025, as Detroit-Windsor Tunnel Day in Michigan. This resolution commemorates the 95th anniversary of the Detroit-Windsor Tunnel, which opened on November 3, 1930, following a telegraphic signal from President Herbert Hoover.

The resolution highlights the tunnel's vital role in facilitating economic and cultural exchange between Detroit, Michigan, and Windsor, Ontario, noting that over 3.7 million vehicles used the tunnel in 2023 alone. It supports more than 325 jobs in Detroit and contributes over $595 million annually to the local economy, enhancing tourism, workforce mobility, and binational commerce. The resolution emphasizes the tunnel as a symbol of enduring partnership and collaboration between Michigan and Ontario, recognizing its importance as it approaches its 95th anniversary and its continued significance in linking the two communities.
