TRIP, a national transportation research group, said 62% of urban roads in the Honolulu urban area are in poor condition. It estimates drivers spend an additional $701 maintaining a vehicle in Honolulu because of the city's rough roads.
The Reason Foundation ranks Hawaii 47th in the nation in state highway performance and cost-effectiveness.
"This report just raises fundamental questions. The basic one is the question that citizens would ask. What have you done with my money? Why are roads in this rating so consistently in the bottom five or seven or eight percent of all the states," said David Hartgen, Emeritus Professor of Transportation Studies at UNC Charlotte and author of the Reason Foundation study.
