Assessment of ND County and Local Road Needs, 2023-2025
This effort responded to the North Dakota Legislature’s request for a study of the transportation infrastructure of all county, township, and tribal roads and bridges in the state. UGPTI developed and analyzed traffic, bridge, pavement and unpaved road data in order to forecast investment needs for the next 20 years. Infrastructure needs were estimated using the most current crop and oil production forecasts, traffic estimates, and roadway condition data. Agricultural and oil related traffic was modeled in detail at sub-county level. Oil related traffic was predicted for individual spacing units, whereas agricultural production is estimated at the township level.
