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
