Alemany Maze is the name given to the interchange between the James Lick Freeway (U.S. Route 101, US 101) and the John F. Foran Freeway (Interstate 280, I-280) in the city of San Francisco.[1] An alternative name for this highway feature is the Alemany Interchange.

History

The Alemany Maze gets its name from Alemany Boulevard, which is named for Joseph Sadoc Alemany. Alemany, who in 1840 completed his studies in sacred theology in Rome at the College of St. Thomas, the future Pontifical University of Saint Thomas Aquinas, Angelicum, was consecrated Bishop of Monterey in California on June 30, 1850, at Rome, and was transferred July 29, 1853, to the See of San Francisco as its first archbishop.

The Alemany Maze is an interchange that originally controlled the separation of traffic travelling between the James Lick Freeway, Bayshore Boulevard, and Alemany Boulevard. The former US 101 Bypass, which followed Bayshore Boulevard to the south, separated from the old US 101 alignment at the Maze. The Alemany Boulevard routing of US 101 was eventually replaced by the construction of the Southern Freeway, later renamed the John Foran Freeway. The routing of US 101 was shifted to the Bayshore Freeway in 1964, with the former US 101 freeway becoming renumbered as part of I-280.[2]

Maze features

The most notable features of the Alemany Maze are the double-deck ramps to and from US 101 from the south and the double-deck portion of I-280 northeast of the interchange. I-280 actually runs east–west through the interchange. The word maze actually refers to the series of interchanges necessary for a vehicle to maneuver in order to navigate their way from a multi-lane freeway to a narrower distribution structure of lanes which funnel to connector exit ramps, similar to the better known MacArthur Maze. Traffic reporters use these words combined with the Alemany Maze to indicate its bottleneck status.[3]
