KLJ has been contracted by the North Dakota Department of Transportation (NDDOT) to perform an Environmental Impact Statement (EIS) and provide preliminary engineering, survey, land development, public and agency coordination, and environmental field studies for the proposed four-lane US Highway 85. The lead agencies include the NDDOT and the Federal Highway Administration (FHWA) in reconstructing a two-lane US highway to a four-lane highway. The cooperating agencies include the National Park Service, US Forest Service, and the US Army Corps of Engineers, along with 17 participating agencies and a stakeholder group. 

This project spans approximately 62 miles and travels through the North Unit of Theodore Roosevelt National Park and borders numerous parcels and functions as one of the primary arterial roadways for accessing various management areas of the Little Missouri National Grasslands. 



KLJ is in the process of conducting the EIS and preliminary engineering to provide a range of reasonable and feasible alternatives throughout the corridor. The team of environmental experts has also performed cultural resource surveys, wetland delineations, paleontological survey, botany, wildlife, raptor, Northern Long-Eared bat surveys, and Dakota skipper surveys for the entirety of the 62-mile corridor. In addition, KLJ analyzed wildlife crossings and accommodations as well as a shared-use path from the Little Missouri River or entrance of the North Unit of Theodore Roosevelt National Park to the Watford City Bypass.



The project’s goal is to address social demands created by the rise in traffic volumes and influx of people; accommodate a mix of industrial, agricultural, and passenger traffic and ample passing opportunities; improve system linkage within the region and state; improve safety; provide capacity for current and future traffic; improve roadway reliability by addressing current height and width restrictions associated with the Long X Bridge; and reduce the potential for wildlife/vehicle-related crashes and minimize habitat fragmentation. The shared use path is from Watford City to the entrance of the North Unit of Theodore Roosevelt National Park.
