According to a post on FrontPorchForum,
The Lincoln Gap Road is now officially re-opened for the (non-winter) season. The road crew plans to take down the "road closed" signs in the next day or two, but those of you chomping at the bits to use this route, may now do so. Keep in mind that this higher elevation travel route can be subject to extreme weather conditions, so use caution when traveling on this road. The steep inclines can get slippery with early morning frost or heavy rainfall. Also please be aware of hikers, bikers, and dogs on the narrow roadway, especially near the top.
