It's crazy to me that North Station hasn't seen regularly scheduled C branch service since 2021. It would be great if the C branch ever gets re-extended to North Station.
I'm pretty sure a lot of the expense at Rivers Edge/Edgeworth is because of pricey retaining wall work. Assembly was built at ground level, Rivers Edge would be atop an embankment.
I'd love to see an infill station at Rivers Edge someday, but it would be costly to construct (estimated to cost between $85M and $95M in 2016). My guess is it's too prohibitively expensive without a considerable amount of redevelopment in the area to boost potential ridership.
Personally, I'm very satisfied with the way SST is coming out, although I completely understand why many of you are disappointed or dissatisfied with the result.
Under basically any other circumstance, I'd say new glass towers aren't exciting or desirable because we've gotten so many of them...
