 Another major benefit of the tunnel will be the redirecting of the large number of vehicles (nearly 16,000 daily; 2009 estimate), many of them container trucks and cruise buses, that cross Biscayne Boulevard (US 1) at NW 5th Street (Port Boulevard), using level streets, such as Northeast 1st Avenue, which for years were the only way to access the port.Along with the capacity of the port, the amount of truck traffic could double after the completion of the numerous port projects.Additionally, the Port Boulevard entrance to the port is closed at night, concentrating all truck traffic during the day.
