The Waldo Grade is the name of a hill before the Golden Gate Bridge leading into San Francisco when traveling southbound on Highway 101, and leading to Marin City when traveling northbound. This grade is generally defined as the stretch of roadway between the Spencer Offramp and Marin City, within the city of Sausalito.[1] This grade is traversed by a full freeway multi-lane highway facility. The Waldo Tunnel at the highest elevation of this grade. This portion of U.S. Highway 101 is an important link in surface transportation connecting the city of San Francisco to Marin County and the North Bay. Nearby locations to the Waldo Grade include: the city of Sausalito, the U.S. Army Corps of Engineers Bay Model, The Marine Mammal Center and the Golden Gate National Recreation Area. In 1982, some of the earth from a landslide at the Waldo Grade was transported to Mill Valley to create a building pad for the Shelter Point office complex.[2]

[edit] In fiction

In the film Bicentennial Man, a futuristic view of a relocated U.S. 101 Highway is used which bypasses the historic Waldo Grade.[3]
