The Savannah River Site's signed SRS highways

[index]

Does anybody have any information on these? Any closer shield photos? I was looking on Google Street View and noticed that they actually sign some of their roads with a county road marker: (Since SC doesn't do these, this is probably one of the few existing instances of this sort of shield on a public road in SC.)

I couldn't find any info on these other than the acknowledgement of the way the routes are on their official website. For such an interesting oddity, that is partially accessible to the public, it doesn't seem like there's much documentation or discussion of it in road circles (and for some SRS Roads like D1, literally no documentation of it exists judging by a Google search, which I found pretty surprising).

SRS Road 1 is actually accessible to the public and has GSV. It looks like the seal on there is of the Department of Energy. Although you're not allowed to stop. Google, however, has misidentified these as SC highways.

Road D1:

SRS Road C seems to partially be SC 125 through the site, before it splits off and goes into a restricted area:

Edit: Looking through some archived and current PDFs on the SRS, I did find some documentation on D1, although it wasn't readily available with a verbatim google search.

https://www.osti.gov/servlets/purl/5324637, Ctrl+F "SRS Road" reveals that there are a lot of these, more than what was initially let on with info that was immediately available and didn't need digging. However the avilable info on these roads seems to stop here, with no more info on SRS roads like A-18 or 9. You can however spot the start of SRS 9 here:

This should make some people's day....

Here is the 1956 map showing their new road system - http://www.vahighways.com/scannex/route-log/images/SRS%201956.pdf

Lettered routes are A-G heading east and 1-9 heading south.  Plus "River Road" at the NW edge of the facility.

In addition to the pentagon routes (posted that way back to at least 1981 from personal experience on my first time through there), there are/were secondary routes.  I have not noticed these posted but was never looking for this (haven't been through there in 20 years).  GMSV along SC 125 doesn't seem to capture any signage of these secondary routes but they could be on tiny postings at the gate or whatever and not very visible from the highway.

The interchange of SRS-C and SRS-2 is the first cloverleaf built in SC.
