Statewide
Before a project is built, a study must be done to determine if it will fill a transportation need, will not negatively impact the surrounding area and fits the department's overall plan. During the study phase, potential projects are analyzed to determine if they are cost effective, while also efficiently improving mobility. Some of these projects have moved beyond the study phase and are under construction.
