(1) Many transportation projects cannot be completed because the transportation construction and maintenance needs of the State of Arkansas far exceed the budget for highway construction and maintenance;
(2) Counties and municipalities have limited budgets for transportation construction and maintenance. As a result, they are often unable to be financial partners with the Arkansas Department of Transportation;
(3) Through the creation of regional mobility authorities throughout the state, counties and municipalities are empowered to become better partners for highway construction and maintenance with the department and the State Highway Commission; and
(4) The funding of regional mobility authorities is intended to supplement state and federal transportation funds. Such funding is not intended to substitute for state and federal transportation aid to counties and municipalities.
