Just found this Article Here. The Cades Cove drive is now cancelled due to the road being under construction during that time.
Finally a stimulus project worth a darn. That road did need work. Read more here: https://sercms.nps.gov/grsm/parknews/arra-funding.htm
FYI....in case anyone wants to visit Cades Cove....Looks like the road work is ahead of schedule and it will re-open on April 24th.
It's open! Great news! Little Wing may just have to take a cruise on the new road. Cades Cove Loop Road reopened to the public April 25. 2010 Thanks to a newly minted road surface, for the first time since 1978 the 11-mile loop around Cades Cove in Great Smoky Mountains National Park is going to feel a little less rustic for bicyclists and motorists. The article says the road was not just resurfaced, but entirely rebuilt.
