Why was PA 100 truncated anyway? I've always found that to be confusing since it no longer connects to the one in Delaware.

My understanding was to keep trucks off Creek Road because of it's design (narrow, some sharp curves, an old weight restricted bridge).

I thought I read where West Chester wanted to keep trucks out of the borough.
But the Creek Road reason is possible too and very applicable.

I wouldn't read too much into it.  They have to call it something for the article, and the general public isn't going to know what "SR 2023" even is much less where it is.

The problem is that it's not SR 2023 or "100 Spur" anymore; it's just PA 100, the southernmost segment of the mainline route. They may have just wanted to distinguish it from the non-freeway portion of 100 north of US 30, but chose to use an outdated term.

I've read somewhere that I-70, I-76 (or I-80S back then) and I-79 all used to pass through Downtown Pittsburgh at some point in its history, and it seems like that all three used the section of what is now I-376 between I-79 and I-279 to get to downtown from the south and west. Did all three interstates use that segment/go through downtown Pittsburgh at the same time? If so, that could most likely be the first 2di triplex in the interstate system's history, predating I-55/64/70 and I-39/90/94.

Part of the (Penn Lincoln) Parkway West, and also 1) utilizing the Fort Pitt Bridge and Fort Pitt Tunnel(s) and 2) carrying US Routes 22 and 30.

According to PA Highways website, none of them were posted at the same time on the Parkway West.

Why does SB I-83 for Lowether Street sign Exit 6C for the loop ramp just south of PA  581?

[74/171FAN]

Why does SB I-83 for Lowether Street sign Exit 6C for the loop ramp just south of PA  581?

That is because the ramp for Lowther St is part of the PA 581 EB ramp to I-83 SB.  There is no way to access this ramp from I-83 SB itself.

I-83 SB traffic must access Lowther St via Exit 41B here.

Then PA 581 uses sequential exit numbers then?  I guess not being interstate PennDOT don't see the need to convert.

[MATraveler128]

PA 378 I think uses sequential numbering. There's a split E-W suffix there.

Well PA 581 is also only seven miles long.  You might would convert Exit 6, and they may be it.

Speaking of 581, is there any practical benefit in having 11 follow 581 for the short distance it does? It seems like a pointless re-route.

That was left over from when PA 581 ended at Carlisle Pike. There was no PA 581 and US 11 was its number plus a short PennDOT reference route between US 15 and I-83.

[74/171FAN]

^At this point, the US 11 reroute is probably still there to keep traffic from following Market St into US 11/US 15 in Camp Hill.

That's a pretty long reference route (2 miles). But OK, thanks for the history lesson.

PA-28 is also sequential numbering.  If any of the state routes that still use sequential, PA-28 is the one route that should, no must, be converted to mileage due to the length of expressway it has.

PA 378 and PA 581 are close enough in my mind.  PA 28 and US 6 really should be converted.

NCDOT uses mileage numbers on US Route freeways. I can see US 22 using mile based numbers on the Lehigh Valley Thruway and the freeway with US 322 and between Ebensburg and Duncansville.

It seems like some states don't milepost non-interstates the same as interstates. For example, in Nevada, the only statewide mileposted routes are Interstates (at least when I was last there in 2016). US and state highways had mileposts which reset at county lines.  Interstates actually did too, but they were very small compared to the standard size state-wide mile markers. I've seen MD have an odd milepost set for US 1 in Harford County which doesn't follow the state mileage.

You could basically do the entire route.  Even the non-freeway portions have interchanges on it  (PA 56, PA 403, PA 26 in Huntingdon, PA 72, PA 934, etc.).

NJDOT does for pretty much all freeway segments that use exit numbering whether they're interstate, US route, or state route. They'll even just go with the on the books mileages in the case of a road like Route 18 which still starts at milepost 6 even though the plans to build south of 138 are basically dead and buried. Same for 21 even though the first 4ish miles of it are urban multilane arterial and it doesn't become freeway grade until the northern end of Newark.
