A hallmark of driving the Blue Ridge Parkway - and most national park roads - has always been the rustic stone or wood guardrails that line the roadway.
But now, that could all change. A few years back, the Federal Highway Administration told the National Park Service at Blue Ridge Parkway that NPS needed to upgrade its guardrails to bring them up to FHA's safety mandates.
Throughout the history of the parkway, there have been five styles of guardrails. Currently, they are predominantly wood rails with concrete posts, Mr. Gary Johnson, the parkway's chief of planning, told me.
While the rails right now are essentially rotten and in desperate need of repair -- that's not the issue with the FHA.
Rather, it's FHA's mandate that there be a 12-foot "clear zone" on either side of the road. Any trees, rocks, or other fixed objects within this clear zone must be removed, according to FHA. As you can imagine, the Park Service didn't appreciate another agency telling it to chop down the ancient trees growing along the parkway. Moreover, the safety measures mean placing additional railing both along the road in places where there hadn't been any before, and near the entrance to tunnels and bridges to "redirect" wayward vehicles onto the road.
This caused concerns with NPS staff members about the cost of such an undertaking, and a change in the parkway's historic/visual character. Not only would the new railing be expensive, but NPS would have to switch from large tractor mowers to weed-eating most of the parkway by hand - a laborious, expensive process.
To placate FHA, the parkway undertook an analysis of automobile accidents and found three very important things:
• 65% of crashes involved deer or other animals darting out onto the highway
• Most other accidents involved people driving too fast
• Finally, there aren't many places along the parkway where people were driving into bridge walls or tunnel portals
NPS went back to the Federal Highway Administration with its data and argued that the need for bringing the parkway up to code by adding the extra railing should be balanced with the need for historic preservation.
"The Blue Ridge Parkway isn't your normal road, and drivers know that...in fact, guardrails sometimes hamper drivers because they aren't expecting them," Mr. Johnson told me.
After much deliberation, the FHA agreed, to a certain extent, with the Park Service. Now FHA is only requiring an 8-foot clear zone, and the two agencies have partnered with a consulting firm to determine methodology to decide where to place the new railing (all old railing is being replaced).
"Looking at the historical accident data was a turning point for us...we're looking to find the trouble spots and fix them," Mr. Johnson said.
The parkway hopes to roll out the new safety measures later this year.
Funding for the new rails is being provided from the Park Service's construction budget. While the average visitor might notice the new railing, it will be a gradual changeover. Great Smoky and Shenandoah national parks have already made the changes required by FHA, but it wasn't an issue for those parks.
"The Blue Ridge Parkway is a cultural resource park, whereas GRSM and SHEN are mostly natural resource parks, and since the parkway is our primary resource, we look very closely at proposed changes to it. We want to maintain the original design of the Blue Ridge Parkway," Mr. Johnson said, explaining NPS's hesitancy to follow the original FHA regulations.
Thankfully, the two agencies have come to a reasonable compromise, and the Blue Ridge Parkway will remain, (relatively) unmarred, for years to come.

Two brief notes: First, the standard abbreviation of the Federal Highway Administration is "FHWA." Typically, "FHA" refers to the Federal Housing Administration. Secondly, it is also good to see the two Federal agencies come to a mutually-agreeable compromise - although you would never have guessed that a mutually-agreeable compromise was already in place from the headline on this post!
Title of this article is a bit misleading, as the issue has already been settled. I expect better from NPT.
The look and feel of the parkway will be at risk once the modifications are made. Replacing and adding new railing will change the look, especially for those that frequent the parkway. It seems pretty straight forward to me.
Guardrails at risk? A parkway remaining unmarred? Hmm.
I think it's worth to point out that this isn't just about guardrails. The FHWA wanted a 12 foot clear zone, which would have meant that NPS would have been responsible for removing anything in that 12 foot zone. Trees, rocks, rock walls built by the CCC, etc would have had to been bulldozed. Moreover, it's a great stretch to say that if there are places where the road is less that 12 feet from a cliff or some such feature, that it would have had to be widened. So yes, the compromise will keep the Parkway relatively unmarred. There won't be mass bulldozings or changes to it. People might not notice or care about these things, but they matter. This issue isn't already settled - until the consultant comes out with the new methodology for determining where to make changes, the railing and walls built by the CCC/New Deal workers are still at risk. I don't want to see a 12 foot clear zone. Do you?

Shenandoah (SHEN) is certainly a cultural park, as well as a natural park. In fact, when the FHWA told the NPS that the stone guardrails built by the CCC had to be replaced to meet modern safety standards, the NPS went through a similar process described for the Blue Ridge Parkway. This was in the early 1990s. The result: the original stonework was carefully dismantled, new, taller, safer, concrete barriers were constructed, and then faced with the original stonework so that only the most careful observer would realize that these were not the originals. It took tremendous effort on the part of both agencies to find a good solution. I commend the staff at the Blue Ridge Parkway for their efforts but I'm disappointed they think they're the only ones who care enough to tackle this problem.
For more on the issue of SHEN's cultural resources, and how the park came to appreciate them, see the article "Cultural Resource Management: at Shenandoah, It Didn’t Come Naturally" which I wrote in 1998 when I was the park's Chief of Natural AND Cultural Resources.

I was shocked to see how many miles of fragile high and rare ecosystems had been destroyed by the building of the Parkway. I think the prudent move would be to remove all the guardrails and then removing the pavement and beginning the daunting task of rehabilitating the road cuts and parking lots.
