The video was posted by a man on social networks about what he encountered when going through an underwater tunnel and unfortunately the tunnel blew up at a corner and the water was overflowing.
into the cellar, the police came and asked him to come back. Not sure if it really blew up like he said, after watching the video most people didn’t believe it that.
They think that in order to build such a large project, they must have calculated very carefully and avoided risks as much as possible. Many people have recognized this as the Baltimore tunnel, The Baltimore Harbor Tunnel is a pair of two-lane road tunnels carrying Interstate 895—the Harbor Tunnel Thruway—under the Patapsco River southeast of downtown Baltimore, Maryland.
The pair of tunnels is 7,650 feet (1.45 mi; 2.33 km) long, stretching from the south shore of the Patapsco River to the north shore near Dundalk. Each tunnel is 22 feet (6.7 m) wide and 14 feet (4.3 m) high, and accommodates two lanes in each direction. The maximum speed within the tunnel is 50 miles per hour (80 km/h). Two-way traffic may occur in either tunnel for overnight roadwork or during emergencies that close down one of the tunnels. The Tunnel has lane control signals to control which lanes are open,closed or as contra-flow traffic.
Both portals have ventilation buildings, with a total of 32 fans in place to replace the air within the tunnels, which is drawn in through the tunnel floors and exhausted through the tunnel
ceilings. The tubes themselves range from a depth of 50 feet (15.2 m) below ground to 101 feet (30.8 m) below ground.
