49 Mile San Francisco Drive

The 49-Mile Scenic Drive is a designated scenic road tour highlighting much of San Francisco, California. It was created in 1938 by the San Francisco Down Town Association to showcase the city's major attractions and natural beauty during the 1939 Golden Gate International Exposition. Originally beginning at San Francisco City Hall and ending on Treasure Island, the route has been modified several times since. Today the route forms a loop proceeding counterclockwise from Civic Center Plaza, and its length is closer to 46 miles (74 km). Owing variously to its length, its labyrinthine route, and the difficulty of driving through a bustling city, the drive remains relatively unpopular with tourists and locals alike
