The Judge Harry Pregerson Interchange is a stack interchange near the Athens and Watts communities of Los Angeles, California, United States. It is the interchange of the following routes:
The interchange permits traffic entering the interchange in all directions to exit in all directions (unlike, for example, the Hollywood Split and East Los Angeles Interchange). The interchange also contains Metro Green Line tracks, direct HOV connectors, and the Harbor Transitway, all of which contribute to the towering, imposing structure for which the interchange is known.
The interchange is over 130 feet high. Opened with Interstate 105 in 1993, the interchange is named after Harry Pregerson, a longtime federal judge who presided over the lawsuit concerning the I-105 freeway's construction.
Motorists entering the interchange on the freeway trunks from all directions have freedom to exit the interchange in all possible directions of travel (i.e., it is a complete interchange). Nearly all ramps are direct (an inherent advantage of the stack interchange design) and can be driven at near-mainline speeds if not congested; the main exception is the ramp from northbound I-110 to westbound I-105, which is a cloverleaf loop.
However, traffic using direct high-occupancy vehicle lane connectors is more restricted. Motorists entering eastbound or westbound on the I-105 HOV lanes may connect to the northbound I-110 HOV lanes. Motorists entering the interchange on the southbound I-110 HOV lanes may connect to either the eastbound or westbound I-105 HOV lanes, while motorists entering northbound on the I-110 HOV lanes do not have direct HOV connectors to I-105 and may only continue northbound. HOV drivers wishing to connect to a direction of travel for which there is no direct HOV connector must exit the HOV lane at a designated entry/exit point before the interchange and use the mainline connectors, as is typical for HOV lanes in Southern California.
