What Cities Have Underwater Tunnels?
Many cities across the globe feature underwater tunnels, serving vital roles in transportation and infrastructure. Notable examples include New York, Detroit, Windsor, Kolkata, and Tongyeong.
Understanding Underwater Tunnels
Underwater tunnels are engineering marvels designed to carry traffic, utilities, or people beneath bodies of water like rivers, bays, or even oceans. These subterranean passages are crucial for connecting landmasses, easing congestion, and facilitating trade, often overcoming geographical barriers where bridges are impractical or less efficient.
Cities with Prominent Underwater Tunnels
Several cities around the world are home to significant underwater tunnels. These structures vary in length and purpose, but all serve to bridge aquatic divides, enhancing connectivity for their respective regions.
Here's a look at some notable examples:
| Name | Place | Length |
|---|---|---|
| Holland Tunnel | New York – New Jersey, USA | 2.6 km |
| Detroit–Windsor Tunnel | Windsor, Canada – Detroit, USA | 1.57 km |
| CESC Tunnel | Kolkata, India | 0.539 km |
| Tongyeong Undersea Tunnel | Tongyeong, South Korea | 0.483 km |
