Is this going all the way back from the freeway to US 202 or ending after central East Granby?
I believe it is starting just west of Newgate Road easterly to the existing four-lane section all in East Granby.
It's a good thing you took those Route 34 pictures, complete with original cement, when you did, because now it's all paved over.
It's sad to see the old stuff gone but traffic flows so much better now with the new improvements.
