• Louisiana ranks first in funding per mile
• Arkansas ranks last among the states in this sample.
A Comparison of Arkansas’s Current Road Quality with the Surrounding States
• Road Quality measured objectively using the International Roughness Index (IRI).
– The IRI is an objective equipment-based measure that allows for cross-state comparisons of road quality.
• Based on the IRI, a score value was calculated and the 7 states within the sample were ranked according to road quality.

Overall Trends
• Tennessee spends less per capita and per highway mile, but ranks highest in road quality.
• Louisiana leads the region in highway funding per mile and ranks second in funding per capita, but has the poorest quality roads.
Overall Trends
The bottom line: Based on our analysis, there is not a significant correlation between the IRI road quality index and funding.
This suggests that other factors may affect road quality other than the amount of funding received.
Conclusion
• Arkansas’s average highway funding since 1982 has increased 3.10%. (in real terms)
• Among the 7 surrounding states, Arkansas ranks:– 4th in per capita funding– 7th in funding per highway mile– 3rd overall road quality (measured by the IRI)
• Arkansas’s road quality is also above the national average.
