Torrey Pines is stunning as it hugs the coastal cliffs between La Jolla and Del Mar. It has always been a place of beauty and enchantment. The oldest image shows a car driving up what is now the park road, but once was the coastal route which made up the early US Highway 101 between San Diego and Los Angeles. The color view to the South leaving Del Mar is almost exactly the same as today. No development has taken place to steal away this view. The same view in black and what shows what happens when to many cars clog the route. The last image is an early photo of the grade leaving Del Mar to the North.
The only section of National Register Designated US Highway 101 is in Torrey Pines State Reserve. It is a narrow ribbon of concrete in the Southern part of the Park.
