Quote from: boilerup25 on December 17, 2024, 11:59:10 AMPennDOT sent an application to AASHTO to get US 15 from I-180 to the NY state line designated as I-99. https://grmservices.grmims.com/vsearch/portal/public/na4/aashto/default (look up Interstate 99 and the 2024 document).
It already has been approved as I-99, back in November. The application you are posting about was filed back in 2021.
Apparently I’m a fan of I-69.  Who knew.

Are they thinking about decommissioning US-15 north of Williamsport in concert with I-99 being approved?

The Ghostbuster

Given the truncation and decommissioning of other State and US Highways parallel to Interstate corridors, I would consider the truncation of US 15 to Williamsport to be highly likely. After all, US 15 was truncated from Rochester to Painted Post due to the construction of Interstate 390.

I remember that NYSDOT originally removed all US 15 signage before later restoring it after designating I-99 north of the PA/NY border, so that would seem to hint at eventual truncation to Williamsport as well. The current interchange of US 15/Market St at I-180/US 220 coming off the bridge over the West Branch Susquehanna River does make for a natural termination point in the future.

The CE Expert System has an entry about signing I-99 along US 15 north of Williamsport.  It looks like the plan is to sign it in 2026.

Wait, there is a second entry about the part of US 220 that is not up to interstate standards. 

Quote• In addition, place Interstate trailblazing signage to address the gap in I-99 from Bellefonte to Williamsport along the I-80/SR220 corridor. The trailblazing is needed to guide drivers between disconnected segment of I-99 from Bellefonte to Williamsport.

I've expressed before that addressing the super-2 section of US 220 from I-80 Exit 178 to PA 477 (inclusive of both interchanges) should be top priority.

The reasons being that:
(A) It is a *relatively* easy/inexpensive project since the ROW is already there; the I-80 interchange would be the biggest hurdle but even that pales in comparison to the complexity of the western I-80/I-99 junction that's being reconstructed currently.
(B) Once the above mentioned reconstruction is complete in a few years, that would allow I-99 to be signed on the I-80 overlap and on US 220 as far east as Jersey Shore, leaving only a single 8-mile gap between Jersey Shore and Williamsport (plus the I-180/US 15/US 220 interchange) to address at a later date, and "Future" signage will suffice for that stretch.

Pfft.  My bet is most people are taking PA 64 to I-80 now due to it being a GPS-preferred alternative.

Well that may be due to the current construction at the I-80/I-99 interchange too.

Routing preference predated that.

Should be easy enough to close the Super-2 for construction then.  :D

Assuming this is in reference to the eastern I-80/I-99 interchange, what's going on there currently?

I was referring to the western one.

That would not have any impact on traffic using PA 64 to get to I-80.

I meant that traffic could be using PA 64 to get to I-80 for the purpose of avoiding the construction at the western I-80/I-99 interchange.

Traffic bound for Lock Haven and Williamsport has, for years, used PA 64 between I-80 and US 220/PA 477 at the end of the 4-lane Lock Haven-Jersey Shore freeway as a short cut. It saves about 3 miles. The current Super-2 part of US 220 goes out of the way for traffic staying on US 220.

That may be true too, but we are talking about PA 64 north of I-80, as explained by Bitmapped.

That shortcut makes me wonder... why was the super-2 US-220 built where it is? Why not build the super-2 along or parallel to PA-64? Just seems like a strange choice back when it was planned.

Once the super-2 is finally widened to 4 lanes and speed increased to 65 mph or 70 mph, it won't make any difference timewise using PA-64 or the out-of-way US-220 alignment, since the freeway will boast the faster speed limit but still.

I'm not 100% sure of the history here, but I think US 220 has always been routed on its existing alignment and the addition of the Mackeyville interchange has only been within the last couple of decades.

PA 64 is in fact old US 220, which used PA 550 to Bellefonte and PA 144 to Milesburg.

Yes, but US 220 was moved onto what is now PA 150 in the 1940s.

The Super-2 section of US 220 was originally built as PA 120 in 1969. The 4-lane part north of PA 477 wasn't constructed until 1976. Looking at it from that perspective, it seems like the alignment was chose to provide the Mill Hall/Lock Haven area with access to I-80 eastbound, with PA 64 providing the corresponding westbound connection.
