Building the Red-Blue connector would get rid of a lot of the transit traffic in the tunnel.

Red is a much more tourist focused line. I suppose they could do it in late May and early June.

A full Red Line shutdown isn't going to happen. Finding enough buses for the Orange shutdown was a challenge, and Red would require even more. The way the Red Line is built also makes it much easier to shut down in chunks. They could shutdown Ashmont and run Braintree at double capacity, then switch to Braintree work and run Ashmont at double, then segmented work on the combined section, followed by a long weekend shutdown of Columbia Junction.
