Weirdest highways in PA.

[PenguinXL2]

I-99 , which ran from I-76 to I-80 starts as SR 26 , becomes a freeway a little past I-80 .

US 22 and 322

I-180 , which goes north , south , east , and west , but is marked as a east-west interstate.

Truck 219 near Ridgway–a one-way alternate route restricted to heavy trucks. It's there because the main road goes down a steep grade and it was judged unsafe to have big trucks heading down that hill.

Google Maps shows it as "ALT US-219": https://www.google.com/maps/@41.4217936,-78.7183617,15z

US 202 in Norristown where the SB lanes are routed on two way Markley Street while its NB counterpart is on one way DeKalb Street.  Then in Bridgeport US 202 Southbound is a freeway while NB US 202 is a surface arterial.

I know that DeKalb was the original US 202 both ways, but Norristown turned it into a one way to help traffic flow, so US 202 had to be rerouted onto Markley. Plus the freeway extension of Markley Street was added later as US 202 for a while used Ridge Avenue to return to its original alignment.

To me PennDOT should make Markley both directions of US 202 and leave DeKalb unnumbered.

Looks like the Google Maps car ignored the prohibition against cars on that road.

Maybe they used a truck!

I guess Google decided they could afford the fine if they got caught.
I did have one trip to Ridgway where some sort of work was going on on "regular" US-219 on Boot Jack hill, and all NB traffic  was detoured on the truck ramp.  (I was just a passenger and not a driver)

PA 32, north end is one-way southbound now for a few miles.
US 1 Roosevelt Blvd., four parallel carriageways. Inner roadways sometimes are express, sometimes serve left turns locally.
PA 29 and US 422, in two sections due to removed central portions, but never renumbered.
Wabash Tunnel, Pittsburgh, a former railroad tunnel that's now a reversible peak-hour roadway.

[agentsteel53]

206 either does not end at its parent, and also contains (as of 2007, anyway) the greatest concentration of old green signs per mile of highway in the state.

PA 248 just west of PA 873...the westbound passing lane is cantilevered over the eastbound passing lane. 

PA 272 is "hidden" along US 222 in Lancaster City.

[Mr. Matté]

I'd nominate PA 61 through Centralia. Goes from a high-speed four-lane highway to a hilly, narrow two-lane road due to the mine fire. Why PA 54 was taken off this route but 61 remained is a mystery to me.

Looks like the Google Maps car ignored the prohibition against cars on that road.

Is there really a fine for cars using that truck ramp or is it more of a situation of "Car drivers, you're awfully stupid to ride down a steep ramp with a lot of potential runaway trucks"?

PA 32, north end is one-way southbound now for a few miles.

I'm guessing this is in reference to your website's page, but I'm looking at recent aerials and GSV and can't find this one-way segment. Near the northern end, there are places where there's a freshly-installed guardrail next to the northbound lanes so perhaps you went through at the time of reconstruction.

Looks like that was done in the last year or two. It was one-way for MANY years.

That hasn't changed.

SR 0284 has cuts every single half mile, possibly for gas lines, that cause a lot of bumps if you even try going fast on them.

[Roadrunner75]

Wabash Tunnel, Pittsburgh, a former railroad tunnel that's now a reversible peak-hour roadway.

The Wabash because it's a reversible roadway, or because you are the only car in the entire tunnel?  I could have stopped in the tunnel and had lunch without ever seeing an approaching vehicle.

I nominate the Goat Path (planned PA 23) in Lancaster County, if grazing paths graded for a four lane freeway with overpasses count.

[sbeaver44]

You all have mentioned some pretty good ones -- PA 248 over itself, Centralia, Wabash Tunnel, Goat Path, etc.

To this I'd add:

• PA 23's interchange with US 202 in Bridgeport
• PA 74's weird little jaunt between Rossville (PA 177 Jct) and Dillsburg when Old York Road is a much better alternative.
• PA 924's random "expressways" at either end
• The stub freeway of I-176 left from when it didn't connect directly with the Turnpike
• PA 12.  Substandard expressway suddenly becomes fairly unimportant local road
• Breezewood?
