The Alemany Maze gets its name from
Alemany Boulevard , which is named forJoseph Sadoc Alemany who was consecrated as the firstarchbishop of the newly formedArchdiocese of San Francisco in1853 and served in that role for many years.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 U.S. Route 101 Bypass, which followed Bayshore Boulevard to the south, separated from the old U.S. 101 alignment at the Maze. The Alemany Boulevard routing of U.S. 101 was eventually replaced by the construction of the Southern Freeway, later renamed the John Foran Freeway. The routing of U.S. 101 was shifted to the Bayshore Freeway in 1964, with the former U.S. 101 freeway becoming renumbered as part of Interstate 280.
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. Interstate 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 ramp s, similar to the better knownMacArthur Maze . Traffic reporters use these words combined with the Alemany Maze to indicate its bottleneck status.References
