Two questions on Clearview and the PTC.
Is the Pennsylvania Turnpike Commission using Clearview?
Yes. PTC practice, which is followed in only a few PennDOT districts at the moment, is to use Clearview for all text legend except route marker digits.
There is considerable variation among PennDOT districts in the way Clearview is implemented. It is quite common for Clearview to be used only for the main legend (i.e., destinations which typically appear in mixed-case), with Series E Modified continuing to be used for minor legend like exit tabs and distance legends. Meanwhile, significant parts of the I-376 redesignation are being done by patching existing Series E Modified signs with Series E Modified, rather than Clearview. The construction drawings for the ongoing I-376 rehabilitation/Squirrel Hill Tunnel height detector retrofit (ECMS 75905) give a good overview of this.
Does the Pennsylvania Turnpike Commission get their signs from PennDOT, make their own or contract them out to someone else?
The PTC contracts out signing. However, a PTC signing contract is an agreement to carry out signing work which is later specified by a work order with accompanying drawings, rather than being detailed in the contract documents themselves.
Here is a breakdown of two recent PTC signing contracts (work authorization drawings obtained through a RTKL request):
* 99-011-RC1U-C: Truck rollover signs plus guide signing for Exit 31 (Lansdale), Exit 44 (Quakertown), Exit 95 (Pocono), Exit 105 (Wilkes-Barre), Exit 115 (Wyoming Valley) (all but the first of these exits being on the Northeast Extension)
* 99-011-RC1T-C: Truck rollover signs plus guide signing for Exit 110 (Somerset) on the main Turnpike
There has, just in the past month, been one other signing contract, but I have not filed a RTKL request for it yet.
