Federal Highway Administration (FHWA), in cooperation with the Arkansas State
Highway and Transportation Department (AHTD), has conducted a comprehensive
environmental study and prepared the necessary environmental documentation
for the proposed Highway 412 bypass in Benton and Washington Counties, Arkansas. The U. S Fish and Wildlife Service and the U. S. Army Corp of
Engineers Little Rock District were cooperating agencies in the preparation
of the environmental documentation.
bypass is proposed to be a four-lane, divided, fully controlled access (Interstate type)
facility constructed on new alignment with interchanges at selected locations.
It would include two 12-foot travel lanes in each direction separated by a
variable width median.
project is known as the Springdale Northern Bypass. The Selected Alignment Alternative begins at an interchange with existing Highway
412 west of Tontitown where the highway presently changes from four to five
lanes and will end with an interchange on existing Highway 412 just west of Beaver Lake. Communities in and around the study area include Springdale, Tontitown,
Elm Springs, Bethel Heights, Lowell, Sonora, Rogers, Bentonville, Fayetteville,
and Cave Springs.
412 is part of a Congressionally designated High Priority Corridor (HPC) running
east and west across northern Arkansas.
