Title: ROUTE 215: OZARK NATIONAL FOREST, ARKANSAS
Accession Number: 00977183
Record Type: Component
Availability: N/AFind a library where document is available Abstract: Route 215 is an improved two-lane facility of approximately 15 mi in length following along the Mulberry River (providing a scenic overlook) with its steep slopes and providing access to the Redding and Wolfpen Campgrounds in the White Rock Wildlife Management Area of the Ozark National Forest. The reconstructed roadway is meant to reduce dust and siltation, thereby enhancing the personal experience of recreationists and other forest users and improving the water quality of the area. Context-sensitive design features were important to this project. Several principles were established for erosion and sediment control during and after construction. The visual environment of the forest, the viewscape from the Mulberry River, and the vistas overlooking the river were deemed extremely important to maintain and enhance. Improvement measures included revegetation of cut and fill slopes, location of borrow and waste areas so as to not be visible from the river, and use of native stone to the largest extent possible for retaining walls, gabion walls, riprap, and ditch lining. Because of the potential instability of the mountain, cuts were kept to a minimum. An additional requirement was to leave in place stone retaining walls at culverts and even a rock box culvert with large stone slabs (it has been covered over by the new roadway and its sides have been extended with pipe). The roadway alignment closely tracked the existing land contours to minimize both cuts and fills.
