Between the Blue Mtn and Carlisle exits, they are currently widening to 6 lanes, and there is a 6-lane section open. It's a little funny that out of nowhere, there is a 3rd lane in each direction, and then later that lane ends. They are also straighening the eastbound exit of the Blue Mtn tunnel. I drove that way over Thanksgiving and I could see the grading. AND, the Blue Mtn interchange is being reconstructed also. The ramp will now go over the mainline on a new bridge, instead of going under.
The 6-lane widening of the first 11 miles of the NE Extension is under construction, and wider overpasses are being constructed on the Mile 320-326 section (approaching the Valley Forge Interchange).
