Wrecked Car Monument on US 15

This same question was posted to the Northeast board the other day with no luck yet - maybe a reader is more familiar with the location and history...   

Does anyone remember the set of white spray-painted car wrecks that were impaled on the top of poles on US 15 just east of Gettysburg?   They were on a piece of property next to a Texaco gas station.  I saw them during the mid 1980's around the time that the Gettysburg Bypass was getting under construction and they seem to have disappeared a few years later about the time that the four lane highway was completed.   Can anyone tell the story of why they were erected and what happened to them?  Is there a photograph out there?

If memory serves me correctly, they were put there as a reminder to slow to 55MPH and drive with caution on the "super 2" stretch of US 15 that ran from the Hunterstown- PA394 BUS 15 exit south to the MD line. US 15 was 4-laned starting in late 87 and finished sometime in 89.

Wonder if they found any Civil War artifacts in the Gettysburg area. My great-great grandfather was at Gettysburg (his unit fired the opening artillery shots of Pickett's charge....Washington Artillery). I have been twice and find new stuff every time.
