you may be correct, and I had the orientation switched around. If you're correct, then the traffic on the other side of the highway would be the Princeton Ave. onramp, and then past that the local traffic on Minor Street.
I-95 in Philadelphia suffers major damage.

They only had the existing footprint with which to work. Pre-tanker fire, it was 4 lanes in each direction, with a shoulder on either side. They were able to create a temporary fix of 3 lanes in each direction with no shoulder. That enables them in the coming days/weeks/months to work on part of the permanent fix, which will become 2 lanes in each direction (with no shoulder) once it's completed. And then they'll remove the temporary fix, and finish the permanent fix. In the end, it will return to 4 lanes in each direction, with a shoulder on either side.
Amazingly, on the moron, excuse me test board, there are posters actually blaming the PA Governor for the accident occurring! That if Mastriano had been elected instead of Shapiro, this never would have happened. It is stunning how fvcked up that board truly is. Thanks Tom for having this site...

Are you talking about the low-hanging test-icular board?
Hadn't seen this posted:
As mentioned earlier, I was doing a virtual class all day for credits. @Nittany.Lion would have mentioned seeing concrete trucks lined up on existing pavement and some type of screed or Bidwell finishing equipment, besides, would have taken time for the concrete to setup and then cure
It would be nice if they would hold up construction until after official signing day in December. We do not want those Philly kids to flip. A little bit of road rage could keep Smart and Saban away...just saying
Yea that place is the island of miscreant toys.
Even a former mod that I "thought" was rational has gone off the deep end. Must be lead in the water or they all ate paint and licked windowsills as kids.
What's bizarre is that it's the same small group of people hating on each other day in and day out. They're participating in groundhog day without gaining any insight.Yea that place is the island of miscreant toys.

Yep. Forgot about the curing time required for concrete. However, I recall something called "high early' or something similar when we used to set manholes on busy streets/intersections that needed to be opened back up by the end of the day. The manhole would be open on the bottom(no base) so we could saddle an existing line.
First time I ever doubted your orientation, Tom.
I've often specified high-early strength for my Verizon roof top projects, but weren't large volume applications such as paving.
UNDERSTANDING HIGH EARLY CONCRETE
"High early concrete is made with high early strength cement using a low water-to-cement ratio. This type of concrete cures rapidly to reach structural quality, about 2,500 psi, within 24 to 72 hours. After curing for about two to three hours, this concrete can support its own weight, and after about six hours, it can handle people walking across the surface. Support for light vehicles develops at about 24 hours after application."
Orientation these days reference sexual preference or some type of hybrid individual!!
There wouldn't have been any advantages to both concrete and asphalt. The choice came down to one or the other, concrete would have added a little risk of weather impact/delay as well as adding curing time (even if shortened) and would take a lot more time/money to demolish later. My thoughts early on were how were they going to make the paving work as support for the barrier walls (could they handle the impact from a loaded semi for example). When the precast sections appeared on site, I thought the sections looked really substantial and would have plenty of weight, were locked together, and had plenty of dead load over the horizontal section to keep them from moving.
The governor's tweet shows the entire clean up of the destruction, and then construction of the temporary fix, in 21 sec.:

I-95 traffic to shift to new travel lanes just 5 months after interstate collapse
The first half of the new bridge at the Cottman Avenue interchange will open Monday night.

Thank you much for the follow up (progress) ....I-95 traffic to shift to new travel lanes just 5 months after interstate collapse

Apparently the driver didn’t know that stuffing a rag into the opening works just as well as the cap.
