Detroit’s nearly 100-year-old underwater tunnel isn’t just a border crossing—it’s a marvel of engineering and teamwork that keeps Detroit and Windsor connected every single day. The original 1930s design still stands strong, thanks to a dedicated crew working 24/7 to keep it safe, dry, and powered (even during blackouts!). Regine Beauboeuf, the first woman CEO in its history, now leads the charge, drawing on decades of experience and a passion for community impact. With four independent power sources, a floating ceiling, and its own vehicle rescue team, this tunnel is full of surprises. What do you think: should we preserve more historic infrastructure like this? #Transportation #DetroitTunnel #Infrastructure
