The 710 (Long Beach Freeway) was originally planned to terminate in Pasadena at the 210 / 134 interchange. For many reasons, this didn’t happen. Today, we are left with two stub sections, one from I-10 to Valley Blvd in Alhambra and the other from the 134 / 210 to California Blvd in Pasadena. This page shows the existing sections as well as some of the proposals for the gap.

A model was constructed of the interchange by Caltrans. A few years ago I was able to get photographs of it. These show a similar interchange design to the drawings above.
