The Frye Museum’s parking lot will close in the fall/winter of 2017/18 to make room for new construction. Here are the latest plans. That’s Skyline to the left, the cathedral to the right, and the Frye at the bottom. And yes, that increasing separation between the towers is real.
From the Frye entry ramp, it should look like this–except they have left out Skyline, which will be framed in the middle.

Looking SE from Columbia St, with Terry Ave shown as two-lane.

Their proposal to make one block of Terry into a one lane pedestrian street.
