How do we build a road?
Planning for the future
We first identify needs and develop a statewide transportation plan that address the state's transportation needs for the future.
Planning the Project
In the planning stage, we determine the project need, funding needs, the goal of the project and we address concerns of the public.
Preliminary design & Environmental process
In this stage of the project, we conduct field surveys, identify environmental issues, address public concerns, develop alternative corridors for the project, prepare an environmental document and hold public hearings. Public hearings give the public an opportunity to learn about the project and to voice any concerns they have about the project.
Final design process
Right-of-way requirements are identified, the final alignment of the road is developed, and construction plans are developed. Public comments are also addressed in this stage of the project.
Right-of-way is a term used for the property owned by individuals that is purchased by the Louisiana Department of Transportation and Development because it is needed for the construction of the road. DOTD meets with property owners and makes an offer to buy the property. DOTD also assists the owner in relocating, if needed.
In order to make room for a new road, any utilities (electric poles and lines, telephone poles and lines, etc.) that are located in the route of the new road must be moved out of the construction zone.
The road is built, and while construction is taking place, we also maintain traffic flow around the construction site for the safety of the road crew and the public.
Once a road is completed, the work never ends. DOTD maintains the road by repairing potholes, keeping the lines on the road marked clearly, and keeping the pavement smooth. When the road becomes worn, it has to be paved again. The right-of-way must also be maintained by removing weeds and mowing grass.
