I saw all the elevated stations included in the project scope, so I assumed they needed structural changes to extend, but lo and behold, the elevated stations are actually longer (at 405 ft) than many Orange/Green line platforms.
So my next question is - if there's no aerial construction, and they preserved land for the at-grade extensions, why the heck does this cost $5 million/station? Even with Cityplace and Mockingbird being somewhat more challenging from a construction ingress perspective, those were built even longer so there's no major construction/digging required there. How much can 200 sq ft of additional station pavement or modifications for level boarding cost?
Also I'm pretty sure the Blue line stations were only included to bump up the theoretical capacity increase for FTA scoring purposes, because I've never seen Blue line trains crowded the way Red/Orange/Green are during rush hour.
