I'm pretty sure everything I've read since they started constructions was that they were going to open US-22 <-> I-79 all at once when it's all done.

There was a recent Post-Gazette article (within the past month) that said waiting until it was all done to I-79 was still the plan.

And they're starting the I-79 bridge work tonight (i.e. digging under the road to build bridges over the Southern Beltway)

Are they maintaining 2 lanes each way on 79?  Are the new bridges able to carry 3 lanes each way for future needs?

Yes, they are maintaining 2 lanes each way on I-79. At least the southbound bridge will have to be 3 lanes + full shoulders to be able to do temporary duty with 4 lanes of traffic. Since the existing 3-lane section ends at the next exit north, I would hope PennDOT builds both bridges to handle 3 lanes + shoulders or at least includes provisions to allow for easy widening.

When the Meadow Lands interchange about 10 miles south was reconstructed around a decade ago, new overpasses were built over Manifold Road. Northbound was 3 lanes + full shoulders so it could carry 4 lanes of construction traffic. Southbound is 2 lanes + full shoulders, which presumably could be restriped as 3 lanes or widened.

Google satellite imagery has been updated for the Southern Beltway, also shows Freedom Rd over the Turnpike work, they did not do all of metro Pittsburgh, still shown none of the nearly completed Comfort Inn on E Ohio Str.

Impressive … I didn't know how far the construction had progressed, almost all of it is under construction between US-22 and I-79.

I count about 8 miles of concrete pavement placed.

The 3-level diamond interchange between US-22 and PA-576 -- is that going to be upgraded to a free-flowing interchange in the future?  It will initially have 4 at-grade intersections between the ramps.

It appears that there was foresight on that segment of I-79, based on the piers at the Manifold Road overpass. However, it appears that the overpasses at the Meadow Lands interchange itself will need to be replaced. The concrete through and immediately to the south of the interchange looks older than the concrete north of the interchange, though, so I wonder if that segment was reconstructed in the late 1980s with the I-70/I-79 north junction.

What is disappointing is that the longest duration contract, the interchange with 79 was started last.  Now we will have 60% of the project complete and sitting unused for 2 years.

Can I offer a reason for why there is space for three lanes over this bridge but only two for the other direction. The bridge is on a tight left curve. Over here there is extra width in the median on the outside of tight bends to increase forward visibility. Could this be the reason for the wider bridge rather than to add an extra lane?

During the reconstruction of the highway, the northbound bridges served two-way traffic and were built to accommodate four total lanes of traffic. The southbound bridge does not exhibit any widened shoulders and when looking underneath the highway, there are no cut-outs for additional girder support without some engineering and reconstruction.

Any word on the schedule for the Section 1 segment between I-79 and PA-43?
I wonder if they have selected the Green Alternative.

There is a small split in the Green Alternative that occurs between McMurray Road and US 19, so it has ambiguity in that regard, and is the only one with such a feature. However, I do think that it makes the most sense, as it takes the most direct path to the Mon-Fayette.

I doubt it..... And that's just talking about "ever" - I'd count on the current interchange for probably *at least* the next 30 years.

Is Fort Cherry Road being extended to PA 980/Robinson Highway to serve as an interchange connection? Also, what's going on just north of that? Did they not secure the land yet?

The PA Turnpike's website refers to it as the Fort Cherry Connector Road.

Off topic question:. I have to go to Pittsburgh on an emergency driving a rental car.  I will need to drive PA 43 between 70 and 40, are they still collecting cash tolls.

No they are not. The entire PA Turnpike System is entirely permanently AET.  (https://www.aaroads.com/forum/index.php?topic=419.msg2505327#msg2505327)

Resurrecting an old topic, but...
I've seen differing estimates of when 576 will be complete between US 22 and I-79. Most articles say fall 2021, but the Wikipedia entry for this road says that weather and other factors pushed the completion closer to summer 2022. Does anyone have any current information on this project?

Opening in parts.

Quote
The Southern Beltway will be open to traffic in October of 2021 with restrictions at I-79. Northbound I-79 traffic will be able to head west on the Southern Beltway and eastbound traffic on the Southern Beltway will be able to head south on I-79. All connections to and from I-79 will be open in 2022.
from: https://www.patpconstruction.com/southern_beltway/22to79/

Assuming the connection to Morganza Road (Exit 19) will be included in the 2022 openings and will not be part of the 2021 openings.
