The Impacts of Energy Development on U.S. Roads and Bridges
Funded through: National Cooperative Highway Research Program (NCHRP) SYNTHESIS Project 45-10 2014
NCHRP Synthesis 45-10 Objectives 1. Document impacts of the energy sector on infrastructure
2. Identify state-of-the-practice strategies used by transpo. agencies to minimize & mitigate those impacts
3. Help transportation managers understand & communicate energy development impacts on roads and bridges
• Choose engineering strategies for managing the impacts • Focus area of FHWA Every Day Counts Round II Initiatives

Project Approach
1. Review current practices by all states re: maintenance and planning in areas affected by energy development
2. Survey all state DOTs & identify 5 states for further study
3. Interview DOT staff, local agencies, and industry for input in the 5 example states
4. Conduct detailed phone interviews to obtain specific details
Background on Issues with Impacts
o Texas, North Dakota, Arkansas Issues with rural road safety & road damage o Pennsylvania Maintenance agreements between PennDOT & energy developers
Data Collection Focus
• Areas of the country where road infrastructure damage from energy development is an issue
• Engineering methods used by agencies
• Tools being used by agencies to assess costs and pay for damage
• Safety implications of increased vehicle volumes related to energy development
States Selected for Detailed Study
• Colorado, Iowa, North Dakota, Pennsylvania, and Texas were selected
Impact level by Road Facility Type
Methods for Quantifying Damage
Methods Reported to Assess Costs
State Practices for Assessing Infrastructure Costs
Iowa Permit cost quantification
Minnesota Web-based road wear cost calculator
Montana Continuous monitoring of population and traffic growth
Texas Ad-hoc method (http://www.roadsfortexasenergy.com). In March 2012, a task force, comprised of representatives from state agencies, local governments and the energy industry, was formed to find ways to address the impact on the state's infrastructure of increased energy development activities
Utah Asset management and maintenance system
Level of Cost Sharing between DOTs and Energy Companies
Defining Challenges
Tools to Address Challenges
State Tools Reported To Address Challenges
Colorado Local agencies are developing fees to address issues with infrastructure damage.
Missouri An approach where the permit fee applied is commensurate with the number of permits issued in order to address funding issues.
Nebraska The cost is being extracted from the corresponding annual budget, as the amount is not significant.
North Dakota The state legislature has provided general fund money from the oil extraction fund to the DOT and local jurisdictions for road and bridge improvements.
Pennsylvania The energy development sector is responsible for the excess maintenance costs, inspection fees, and roadway condition survey costs.
Texas A unique relationship between the current/future energy sectors and railroad commission has been developed. Development of standard lease agreement with an associated fee. Temporary use of water lines (for transporting liquids) in state ROW to reduce roadway truck volumes.
PennDOT Process for Maintaining Roads
Conclusions • Strong correlation: Increase in damage and
congestion on roads and bridges near energy development activities
• Engineering approaches include: – Increased lane widths & adding paved shoulders – Increasing pavement thickness – Stabilization of unpaved roadway surface layers – Jumper bridges
Future Research
• Lack of quantitative information being collected • Lack of information on safety and crash statistics,
especially low volume roads • No accurate pavement life predictor nor
estimating damage • Investigation into detour routing • Quantify the extent of damage on more high-type
roadways – Current studies focus on secondary roads in primarily
rural locations
