The Stack is a colloquialism used to describe the symmetrical four-level stack interchange in Downtown Phoenix in the U.S. state of Arizona that facilitates movements between Interstate 17 and Interstate 10.[1] It was the Phoenix Metropolitan Area's first four-level stack interchange upon its completion in 1990.[2]

[edit] Description

In 2006, the Stack interchange saw an average of 235,000 cars pass through it daily on Interstate 10 eastbound and westbound; and an average of 120,000 cars on northbound and southbound Interstate 17.[3] The interchange constitutes exit 200A on Interstate 17 and exits 143A and 143B on Interstate 10. Access is provided in all directions and there are no direct HOV lane connections. Interstate 17 does have two frontage roads running both southbound and northbound through the interchange known as Black Canyon Highway.
