I have a photo of when I-79 was still routed downtown...from a flooded Parkway East.

I like that picture as well as the one you have of the workers replacing the 76 shield with a 376.

They were changing the "279 SOUTH" to a "376 WEST" at the time of this post.

Don't worry, I've been saving pictures of the change.  So, once it's all done, I'll post them.   23 pictures and counting as of right now.

Is that what is going on in that picture??  I had thought that the 376 designation had just been assigned, and the 76 that the workers were holding up was just for show, being a replacement for 80S, which was the number being retired in entirety.

Jake,

80S never went through Pittsburgh - originally 70 did until 1963.  Then 76 did.  376 replaced 76 to the point.

See the bottom of Jeff's page:
http://www.pahighways.com/interstates/I376.html
"Former designations"

80S only existed on the Turnpike.

Now a gem of a find would be a I-70S PA shield since that route only existed until 1963.

[agentsteel53]

where did I-70S go in Pennsylvania?  I just know of the Baltimore/Washington split further east.

IIRC
When I-70 went through Pittsburgh (up from Washington, PA and down the turnpike), I-70S was the current I-70 from Washington to the turnpike at the New Stanton interchange.

It went between Washington and New Stanton at the time mainline 70 went into Pittsburgh.

Nothing really special about the procedure.

And prior to that it was PA 71 Alt.  Don't forget the brief section from the Hunker interchange (old US 119) to the Turnpike was at grade til about the same time I-70 moved to where it is at today.

You can find a number of older I-70 PA shields in and around the interchanges on that old stretch. (not the best shot as i was still using a cheap film camera then).

I know this is changing the subject slight but lets not forget the short-lived white on green PA 43 TPK shield from 1999-2000.

I'm curious - what are the dimensions and weight of an exit tab?

[J N Winkler]

Weight depends on the substrate type and thickness.  Height is typically 30" (though California uses 24", and Arizona DOT uses 36"), and width is whatever it has to be in order to accommodate the legend--probably 150"-180" for the tab being lifted into place.

As a general rule, in states which use extruded panel or extrusheet construction for large guide signs, large guide signs need to be hoisted in place mechanically and then held suspended in the air while they are bolted to the sign structure.  This is not necessarily true for exit tabs, however, since they have a far smaller area and so are much lighter.  It looks as if this exit tab is light enough for two men to handle with a cherry-picker.

I am not sure what kind of sign substrate PennDOT uses now.  In the past they have used laminated panels--to all intents and purposes it looks the same as the Douglas A-10 honeycomb which Caltrans has traditionally used.

Still, for me, it's saying goodbye to an old friend since all I've know on that section of highway is I-279.

Me too, even though I'm not a Jersey native.  I have tons of family in Pgh and I go every year.

[CanesFan27]

Goodness i hate to see how you would have been in the 1970s when it went from I-79 to I-76 to I-279.

Or Crosstown Boulevard going from I-479 to I-876 to I-579.

Apparently they will be working switching/modifing signage around the point nightly this week.

Their article is inconsistent though, as the first paragraph it says the work is being done southbound.  The second paragraph then says it will be on the bridges' upper decks... which are Northbound.

About time. lol.

I was just on the Parkway West from Robinson to Blvd of the Allies, and from Greentree Rd out past the airport. Not one I-279 sign I saw.

Interesting, north on PA-60, there's I-376 shields covered by PA-60 shields waiting for their unveiling.

The I-279 shields were gone going Inbound on the Parkway West as of the time I took all those photos of the new signage.  There were (at that time) still up going Outbound.

So, I had a feeling that the Outbound ones days were numbered when they had disappeared from the Inbound side.

I still don't get why PennDOT didn't do that on the signage @ I-376(I-279)/I-79 when they installed new signage as part of the missing ramps project.

[rickmastfan67]

They now have the signs on the top of the Fort Pitt. Bridge changed over.

Just happened to catch a view of the top deck of the bridge while they had the camera zoomed in clearly showing the new exit numbers.

[PAHighways]

They're just playing catch-up.
