Architecture critic Reyner Banham once wrote, “The language of design, architecture and urbanism in Los Angeles is the language of movement. Mobility outweighs monumentality there to a unique degree.” If you buy that argument, it would follow that our freeways and freeway interchanges should be considered among our greatest landmarks. Take for example the carpool lane of the Judge Harry Pregerson Interchange, which connects the 110 and the 105: More than 130 feet high, it offers drivers a breathtaking view of sprawling, almost oppressively flat South Los Angeles, albeit one that must be viewed quickly to avoid careening off the side. The interchange is named for the New Deal–style, 90-year-old, still-serving activist judge who forced Caltrans into providing housing, jobs and other services to those living in the shadow of the 105, the last freeway built in L.A. Unfortunately, this majestic byway is now a toll lane, which means you need a special transponder from Metro to ride it. —Hillel Aron
