Our mission is to provide a safe, well maintained road and bridge system that will ensure reliable and convenient access to County services, facilities, recreational and natural resource areas and employment centers; to enhance the quality of life of St. Louis County residents; and to promote the economic development of the area.

During the 2018 construction season, St. Louis County will invest $47 million in its roads and bridges. These projects will be funded from a combination of State Aid and Federal Highway funds, along with revenue from the Transportation Sales Tax.
