Condition Assessment & Funding Needs For North Carolina’s Highway System
• Reporting Requirements• Overview of the System• Assessment Methodologies• Current Conditions• Funding Needs• Maintenance Operational Improvements
Biennial Report on Maintenance Requirements. G.S. 136-44.3
• The annual cost of routine maintenance
• The cost of eliminating maintenance backlog
• Annual resurfacing cost based on a 12-year cycle for
primary roads and a 15-year cycle for other systems
• The cost of eliminating any resurfacing backlog

• Senate Bill 1005– Traffic Mgmt. System Improvements - $ 15 million– Primary Pavement Preservation - $ 135 million
Impact of SB 1005 on Pavement Needs
• Authorized use of Highway Trust Fund cash balances
• Targets major primary system corridors
• Provides approx. $423 million over 3 years
• Approx. 5,500 lane miles will be strengthened and resurfaced
• Helps eliminate resurfacing backlog
• Reduces pavement needs
