There are plans for upgrading the James Dean memorial Junction, which is where the 41 and 46 diverge at Cholame, California.

What would be the best method of upgrading this junction, which currently only has yellow flashing warning lights? The hardware for an all-way stop is already there, as one merely has to change the yellow lights to red and install a few road signs. A traffic signal can utilize the existing masts and mast arms used for the blinking yellow light, although it would require more hardware. A roundabout would require quite a bit of construction, while a full high-speed interchange requires a lot more construction.

I am surprised though, that at least a roundabout, if not a fully signalized junction, had not been constructed there in the past sixty-four years.

Max Rockatansky:
I was under the impression this would be a full flyover ramp for CA 41 northbound as it splits from CA 46 east?  Regardless my personal opinion is that 46 ought to be four laned east to I-5 and CA 41 north to CA 41.

A roundabout wouls be cheaper, and could accommodate the traffic at that junction. There does not seem to be enough traffic to warrant a signalized junction much less a full freeway interchange.

Concrete Bob:
My vote is on the grade-separated interchange:

I am with Max on the 46 Expressway option.  I would continue with SR 46 as an expressway east to 99 (after 58 is finished as a freeway to I-5).  I would combine the 46 upgrades with a four-laned 41 expressway to Lemoore, followed by a full freeway on 41 north through Fresno to Route 145.

I am surprised that there is not a traffic signal there already.
