The Washburn Tunnel in Houston, Texas, is the only remaining vehicular tunnel in the state and the longest in the South, measuring nearly 4,000 feet. Opened 75 years ago, it connects two suburbs beneath the Houston Ship Channel and features a two-lane, non-toll path. Drivers can traverse the tunnel at 35 mph, experiencing the sensation of being underwater during the one-minute journey.
