🚇 Shanghai tunnels

The Old Portland Underground, better known locally as the Shanghai tunnels, is a group of passages in Portland, Oregon, United States, mainly underneath the Old Town Chinatown neighborhood and connecting to the main business section. The tunnels connected the basements of many hotels and taverns to the waterfront of the Willamette River. They were built to move goods from the ships docked on the Willamette to the basement storage areas, allowing businesses to avoid streetcar and train traffic on the streets when delivering their goods.
