The state’s main aid program for supporting local roads could deliver support more efficiently to communities with the greatest need, raising the question of whether it’s time to revisit how these dollars are distributed. The state’s General Transportation Aids (GTA) program is the second-largest program in the Wisconsin Department of Transportation; at $508.2 million in 2021 alone including supplemental payments, it also represents the second-largest form of state aid to municipal governments in Wisconsin, and one of the top forms of aid to counties. The GTA program is growing more rapidly than other forms of state aid such as shared revenue payments, further highlighting its importance.

The WPF project analyzed GTA distribution allocation trends, compare them with peer states, create a system-level planning tool, and offer recommendations.
