Judge Harry Pregerson Interchange - Layout

Layout

Traffic entering the interchange on the freeway trunks from all directions has freedom to exit the interchange in all possible directions of travel (that 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.
