CA: CA-56 western ending in wrong place?

[rickmastfan67]

Should we keep it on the freeway to I-5 instead of having it use the at-grade access to I-5?

This signage seems to indicate that only the freeway is CA-56.

Thus, the graph connection between the two should be @ I-5's 33A point instead of currently @ I-5's 33B.

If this change is made, would require a news entry.

Why are 33A and 33B separate in the first place? Looks like a clear 1PPI.

Caltrans' Postmile Query Tool seems to disagree with you about the official west end of CA 56. But cl94 is familiar with the quirks of the PQT and can weigh in on this.

Looks like the identical problem appears with WA 500 in Vancouver, with a very similar interchange setup (it's a 1PPI in this instance, however). Setting aside on whether it should be a 1PPI or 2 (I'll just say I think it should be two in instance), both interchanges need to be looked at and fixed.

I'll take a look at this in the coming days and add my take.

So, the official west end of CA 56 as mileposted is where the NB ramp to the CA 56 freeway departs from the C/D road. This would imply that the end is 33A, and in a world where 33A/B are split, that's where the point should go.

The question now is if we keep it as two separate points or merge to 1. My preference here would be 2 points, but it may be worth holding off until we decide on a "standard" fix.

Well, since both points (33A & 33B) are currently in-use in I-5's file, I'd say stay as-is on I-5 as people have already accurately mapped were they left/started on it.

So, all that would need to be 'adjusted', would be correcting the CA-56 western end, since you say it does indeed end @ I-5's 33A point.
