2. The Tunnel Had to Cease Production During World War II
During World War II, America was in desperate need of the steel and simply could not spare any resources for the construction of the tunnel. All the supplies were going to munitions and aircrafts. It seemed public transport was the least of our concerns.
This lead to the complete abandonment of the tunnel’s construction for several years. It was only after the completion of the war in 1945 that construction of the tunnel began again, finally opening its doors to the public in 1950.
