Route Description
The pair of tunnels is 1.45mi. 7,650 feet (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).
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.
The tunnel and Thruway are maintained by the Maryland Transportation Authority, which currently charges a toll of $3 for cars in both directions. Tolls may be paid with cash or with E-ZPass.
