If you think Metro is not serious about building the SR-710 Tunnel(s) take a look at the following three attachments from Metro's Technical Advisory Committee Meeting handouts:
1. Preliminary Operations and Maintenance control (OMC) Building Concept
2. North Portal (Pasadena) Ventilation Locations - location B is at the Colorado Blvd Bridge - location A is located at Pasadena Avenue and Walnut. Which one will they choose?
Also notice the location of the OMC Building between Del Mar & California.
3. They got it landscaped too - Preliminary North Portal (Pasadena) Landscape Concept.
