The Judge Harry Pregerson Interchange is a stack interchange near the Athens and Watts communities of Los Angeles, California. Though the interchange permits traffic entering the interchange in all directions to exit in all directions (cf. Hollywood Split, East Los Angeles Interchange), the interchange also consists of direct HOV (high-occupancy vehicle) connectors, Metro Green Line tracks, and the Harbor Transitway, all of which contribute to the towering, imposing structure for which the interchange is known.

Opened with Interstate 105 in 1993, the interchange is named for Harry Pregerson, a longtime federal judge who presided over the lawsuit concerning the I-105 freeway’s construction. Shortly before the interchange opened, filmmakers had access to use it for the 1994 motion picture Speed. In one of the movie’s best-known scenes, the bus must jump across an unfinished construction gap in an uncompleted elevated freeway-to-freeway ramp while still under construction.

In 1996, the U.S. Federal Highway Administration recognized the Interstate 105/Interstate 110 interchange with an Award of Merit in the Urban Highways category of its biennial Excellence in Highway Design awards. The award recognized the interchange’s design which sought to improve traffic congestion, safety, and air quality. [Source: Wikipedia]
