Duchesne County hired Jones and DeMille Engineering in spring 2024 to conduct a study on the effects of heavy haul traffic generated by energy production on the County's transportation infrastructure. A draft summary of their analysis, findings, and solutions can be found at the link provided.

DRAFT ENERGY DEVELOPMENT HEAVY HAUL TRAFFIC STUDY

Highlights of the study are:

• Analysis based on AASHTO 1993 Road Test Method for Pavement Design
• Data collected from energy producers, AI analysis of roadway conditions, FHWA and UDOT cost indexes, and roadway cores indicating pavement depth and base materials.
•  Findings
  • Cost to Replace the Average Mile of Paved County Road (2024) = $1,767,000
  • Cost of Average Mile of Graveled County Road (2024) = $141,360
  • Rate of Reduced Service Life of Average Impacted County Road per Well = 2.3%
• Preliminary Paved and Gravel Road Formulas for the Roadway Cost from Energy Development Traffic Were Generated
