Interesting car... 1913 with a V-radiator and electric lights, and a gas spotlight. The tires look too big to be 30x3, so I'm guessing it has Firestone demountables on it too, but I don't see a spare.
That's a serious 'searchlight' on it, with what appears to be a sizable cable to it!
I have never been able to reconcile the number of railway ties used on the plank road to the length of the road. This picture provides a reasonable explanation in that the plank road was only over the worst sections, as shown in this picture.
There is a section of the old plank road in the Auto museum in Balboa Park, San Diego. Many years ago when we would drive through that area, there were still some planks visible in the distance.
The last time I drove that section of I-80 there were still some remnants of the plank road visible from the freeway.
I'm a little confused - If the photo was taken in the Imperial Valley, am I correct in thinking that I-80 is nowhere nearby? Perhaps you meant I-8?
Old Highway 80 was changed to I-8 in the early sixties.
It was US 80 - Not Interstate 80 (I80) which we know today.
