Change provisions relating to the priority of projects and requirements of the state highway system plan

LB 449 amends Nebraska's state highway planning rules to prioritize preserving existing roads while establishing new criteria for project selection. The bill requires the Department of Transportation to consider traffic volume, safety, economic development, and population trends when setting priorities, and mandates that at least 70% of highway revenue raised in each district must fund projects within that same district. It also requires the highway system plan to designate expressways and account for district-specific revenue allocation. These changes directly affect Nebraska's transportation districts, local projects, and citizens by altering how highway funds are distributed and prioritized.
