widen the US 321/421 concurrency from this junction to their junction near Vilas, although this project is currently unfunded. There is a feasibility study (FS-0511A) in progress to examine the possibility of widening US 321 from the junction near Vilas to the Tennessee state line. If both of these projects were completed, then US 321 would be a four-lane highway through the entire state. Tennessee As it crosses into Tennessee, US 321 enters the Cherokee National Forest, and continues westward through the rugged valley between Pond Mountain on the south and Watauga Lake on the north. The highway passes numerous campgrounds, boat launches, and other lake-related recreational areas as it winds its way along the shores of the lake. South of Butler, the highway joins SR 67, which enters from the Mountain City area to the northeast. The Appalachian Trail crosses US 321 at its intersection with Shook Gap Road, just before the highway exits the national forest. At Hampton, US 321 intersects US 19E, and the two highways run concurrently northward into Elizabethton. US 321 inverts directions in Elizabethton: the road is designated as southbound in both directions driving away from its intersection with US 19E. It is conterminous with US 11E through portions of Washington and Greene counties. In Greeneville, the highway continues south into Cocke County. At the Cocke-Greene County line US 321 becomes a four-laned divided highway and bypasses Parrottsville. The four-lane section ends just before US 321's junction with SR 160 and crossing I-40 at Newport. The stretch of US 321 from Newport south to Cosby and southwest through Pittman Center to Gatlinburg parallels the northern boundary of the Great Smoky Mountains National Park and is quite scenic. From a point between Newport and Cosby to the intersection with the Little River Road, it is concurrent with SR 73. In Pigeon Forge, concurrent with US 441/Great Smoky Mountains Parkway, US 321 is a divided, multi-lane traffic-laden thoroughfare where it serves as the city's main route, lined with hotels, outlet malls and amusement facilities. Veering southwest of Pigeon Forge, the highway takes on a more rural character as it traverses Wears Valley, and narrows down to two lanes until its junction with SR 73 Scenic (the Little River Road) at the Townsend entrance to the park. It is concurrent with SR 73 from this junction to its terminus. With the exception of a section between Townsend
