Fort McHenry Tunnel, tunnel in Maryland
Fort McHenry Tunnel is a road tunnel in Baltimore that runs beneath the harbor to carry traffic across the city. It serves as a major crossing point, allowing vehicles to pass under the water instead of taking longer surface routes.
The tunnel opened in 1985 as a major infrastructure project for Baltimore. It was among the longest underwater tunnels of its era and significantly improved traffic connections across the city.
The tunnel is open daily for through traffic and straightforward to navigate if you follow normal traffic rules. It is well lit and regularly maintained, making the passage safe and efficient.
The tunnel is notable for enabling one of the longest underwater drives in the US while running entirely beneath the harbor. The drive through takes only a few minutes, yet gives an unusual sensation of traveling under so much water.
