(For I-79 at PA 910)  PennDOT - District 11 News: I-79/Route 910 Wexford Interchange Project Online Virtual Public Meeting Tuesday

Not gonna lie, but this is needed.  About the only way I could see them making space between I-79 & Brandt School Road on PA-910, is to convert the I-79 interchange to a SPUI.

However, I could see that if (and it's a big if) they can move the NB ramps way closer to the bridge, I think there should be enough space to convert it to a DDI as long as they connect Sunny Hill Road on the SB side to connect to the Northern spur of Nicholson Road @ that traffic light.  This way, they wouldn't really have to mess with the SB ramps (sans making the split for the DDI).

Let's just avoid the SPUI problem by moving all of the ramps to the west side of I-79.  (basically that is what was presented tonight, I am unsure why they are calling it an offset SPUI)  Having stated that, this could arguably end the graph connection between I-79 and PA 910 in Travel Mapping.

Looks like what PennDOT did on US 422 for PA 23 outside King of Prussia.  The big difference is there is only one flyover ramp (for the off-ramp from 422 EB to PA 23) and both directions of PA 23 have their own ramp to 422 WB.  They eliminated a weaving area on one side and two adjacent intersections on the other (similar to what you have now in Wexford).

Also appears the 79 NB off-ramp will have two right turn lanes with a painted separation between them.  If they keep that design, I'm guessing the outer lane would allow right on red and the inner lane would not?

Mr_Northside

Not a bad design.   I'd think just spacing out the distance between the 79 NB-off/on ramps and Brandt School Rd will help a lot.
I do wonder about the decision for PA-910 (and non-910 Wexford Bayne Rd beyond) having the right lane be right-only to NB I-79 and only continuing with one thru-lane to non-910 Wexford Bayne Rd, as opposed to being a right/straight option and continuing 2 thru lanes (and allowing a dual left from the 79 NB off ramp) - I'm guessing traffic pattern studies shown that was the best decision.

While that could be possible, I don't think PennDOT does that very much.   If I had to bet, I'd bet neither lane will allow right-on-red.  I suspect they'll advise that traffic in the far right lane be destined for Brandt School Rd, and the second right for 910/VIP drive  (somewhat like now)
I don't have opinions anymore. All I know is that no one is better than anyone else, and everyone is the best at everything

Heh, shocked that they'd want to turn it into a SPUI on the west side of the interchange and introduce two new bridges to maintain.  Thought a DDI would have been a better choice as long as they moved the NB ramps closer to the mainline I-79.

Plus, would have though they'd leave a slip ramp from the WB PA-910 lanes to the NB lanes of I-79 and keep that movement on the east side of the interchange.  Would be better IMO & keep that movement freeflowing.  That way, they could have 2 straight lanes thru the traffic light, instead of 1 straight & 1 right.

"Diverging diamond" interchanges are terrible in areas with high traffic volumes. In Georgia, the I-85 interchange at Pleasant Hill Road and the I-285 interchange at Ashford-Dunwoody Road both have poor service levels. SPUIs are far superior.

ARMOURERERIC

If I were doing it, and I am familiar with the topology, though not the NIMBY politics, I would do a 6 ramp Parco as follows:

79 north, ramp to Brant School between Sorgels and Orchard Hill Church labeled:

To PA 910 East
Brant School Rd
Wexford

Then an off ramp and on ramp to 79 North connecting to the intersection of Mingo and Neely School Rd labeled:

To PA 910 West
Neely school rd
Bradford Woods

For South 79, keep the existing off ramp for

Wexford Bane Rd
Ambridge

Then SB Off ramp and on ramp to 79 South meeting at Nicholson South of Blaymore.  The ramp labeled:

To PA 910 East
Nicholson Rd
Wexford
Franklin Park

No extra bridges needed
No signals between Nichloson and Brant School
New signal on both Nicholson and Mingo Roads

With the help of friend of the site, PAHighways.com's Jeff Kitsko, I was able to update the Pittsburgh International Airport Ghost Ramps history page.  The new map shows the routing and planned 3.67-mile extension of the Beaver Valley Expressway (then PA 60 now I-376 and 376 Business) to serve as a bypass of the former main entrance to the former Greater Pittsburgh International Airport.  The new map details the plans for this highway, which for over 30 years was a set of two-lane ghost stubs that dead-ended into a hillside at the cargo entrance to the airport.

The Beaver Valley Expressway Extension would include an interchange at Beers School Road (now University Drive) and a different version of the Thorn Run Road Interchange that exists today.  Also, a never built trumpet interchange (called the McCutcheon Interchange) would lead to a new terminal access road.

Of course, the extension/bypass was never built - and would be moot nearly 20 years later when the new Landside Terminal and accompanying freeway was built.

A few days ago in my hometown FB group someone posted a photo of this wall map of Southern Allegheny County.  Like many maps of the era, the map shows the new PA 48 corridor.  However, this was the first map that I have seen that gave a good idea of the route north of US 30 and into Monroeville.


"Highlights" include that the new 48 would after crossing US 30 (east of where the old K-Mart Plaza at PA 48 was/is) that it would head into the Turtle Creek Valley and into the southern limits of Trafford before turning west to parallel the railroad and PA 130 through the valley.

It crossed 48 again at the current-day PA 130/48 intersection (where the Sheetz is) and then would turn north to parallel Mosside Blvd (PA 48) to the west along Tilbrook Road.

The New 48 would cross PA 48 again at Northern Pike before tying into the US 22/Parkway East/PA Turnpike Interchange.

The routing would have taken out the Haymaker Village Shopping Plaza along PA 130 in Trafford.  I wonder if the interchange at the PA 48/130 intersection (at the north side of the Wall Bridge) would have had possible connections built-in for the Tri-Boro Expressway (never made it that far east anyways).

Finally, it would have been interesting to see how the New 48 would have wound around the Gateway High School Complex at 48/Northern Pike.  Gateway High School opened in 1958 - and most published corridor routes for the New 48 came out in the mid-late 1960s.

You really never know where you can stumble across a clue in a roadgeeking mystery.
I've updated the NEW PA 48 page at Gribblenation as a result:

Looks like the I-79 crossover north of the Ohio River has been a trouble spot since it opened this past weekend.  PennDOT is making changes and likely reducing the speed limit (they had kept it at the normal 55 MPH) but the southbound side is down to one lane.

https://www.wpxi.com/news/local/penndot-making-changes-after-crashes-new-i-79-crossover/DCH3OU6WP5G2BLHOT6BCMBNWUY/

They are also using these oddly shaped metal barriers instead of concrete.  They are wider at the top than the concrete ones, and I know someone who didn't realize that and ended up with a long scratch down the side of their car.
