Project Studies: San Antonio District

Before a project is built, a study is 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 this phase, potential projects are analyzed to determine if they are cost-effective and also efficiently improve mobility. Some of these projects have moved beyond the study phase and are under construction.
