I have responses to your questions below in in the same order as numbered in your email. However, before we get too far into the AGT design, I want to remind you of the standardized transition buttress that was recently designed here at MwRSF. This buttress has been evaluated to MASH and is compatible with a variety of transitions, curbs, and adjacent concrete barrier configurations. We highly recommend utilizing the standardized buttress in your approach transitions in the future. I have attached a TRR Journal paper to this email that explains the design and some implementation issues.

Please review these comments, attached paper, and the MGS stiffness transition report and let me know if you have further questions.
