Frequently Asked Questions (FAQs)

  1. 1. Louisiana’s Governor and Secretary of Transportation announced in January 2018 that funding was being secured to facilitate the reconstruction and widening of I-10 from the Mississippi River Bridge to the I-10/I-12 split. How is this moving forward if the environmental review process has not been completed?
    1. State officials are arranging funding sources to support the implementation of improvements that result from the environmental evaluation, not to predetermine the outcome of the evaluation. LA DOTD processes are outlined at this link: These processes begin with a Stage 0 (Feasibility Study), continue through a Stage 1 (Planning/Environmental) phase and then into funding efforts, which takes additional time. By initiating funding efforts concurrently, state officials are seeking to cut down the wait times for forward movement. The Stage 1 environmental study is still in progress and is expected to be completed by the end of 2018.


  1. 2. When will the public learn more about potential impacts to local residences/businesses of the widening effort?
    1. The project team is obtaining additional traffic analyses and compiling overall results from the many reviews that have been underway. Once these are brought together, project concepts with corresponding maps showing potential locations for construction to occur will be shared at public meetings. Current projections are that these meetings will be held in spring 2018. In many areas, the team is aware that existing rights-of-way will be sufficient for widening needs.


  1. 3. Adjusting the Washington Street exit was part of the discussion during the Stage 0 study, but LA DOTD is handling this piece in a different way. How is this being addressed?
    1. LA DOTD was able to initiate a separate project to address the traffic issues at I-110 and the Washington Street exit on a more immediate basis. LA DOTD has awarded a contract to construct a new exit on southbound I-110 to connect with Terrace Street.  The construction time is approximately 12 months. Under the concept for the I-10 corridor, the existing eastbound Washington Street exit will be combined with the Dalrymple Drive exit rather than having two separate exits.  This is necessary to provide an eastbound on-ramp from Dalrymple Drive which does not presently exist.  The new eastbound on-ramp from Dalrymple will not be across the lakes.


  1. 4. The last public meetings related to this project were held in 2016. What has occurred since that time?
    1. The Stage 0 Feasibility Study included public meetings in August 2015 and March 2016. The final Stage 0 report was issued in August 2016 for public comment. The second stage of the LA DOTD process, the environmental/planning stage, began in 2017. The project team has been conducting intensive analysis on traffic, line and grade, structural review of existing infrastructure, and constructability reviews of the many segments in the corridor. At the same time, numerous environmental studies have been underway.


  1. 5. What exactly is the difference between Stage 0 and Stage 1?
    1. The term “Stage” refers to the progress of a project as it moves through LA DOTD’s Project Development Process, Development-Process.aspx. Once a project is selected for study, it enters Stage 0, which is the feasibility study stage that allows for multiple alternatives to be considered and determines if a project is truly feasible. Stage 0, as it relates to this project, was completed in 2016 with a final round of public meetings and the release of the Stage 0 document, available for review on For this project, Stage 0 resulted in one basic concept that moved into Stage 1, Planning and Environmental.  During this stage, the project is further refined to the extent that the range of positive and negative effects can be reasonably estimated.  Further, potential community mitigation and enhancements are considered in Stage 1. Stage 1 involves public meetings, a public hearing, and a decision document, in this case, an Environmental Assessment.


  1. 6. When will we have another public meeting and what will be presented?
    1. We anticipate holding a round of public meetings, one in West Baton Rouge Parish and one or two in East Baton Rouge Parish in spring 2018. The team will present updated traffic study results, an update on the project concept studied in detail since completion of the Stage 0, a summary of potential positive and negative effects (to include construction staging areas), potential community mitigation and enhancement measures, and offer an opportunity to provide public input on the materials presented.


  1. 7. I am very concerned about noise, will noise study information and noise barrier locations be included in the public meeting presentations?
    1. The noise study along with potential barrier locations and other noise mitigation measures will be presented during the public meetings and at the public hearing(s).


  1. 8. Will construction of this project involve driving piles?
    1. Additional or new supports/piers needed for potential construction would be installed using a drilled shaft method.  The noise and vibration associated with pile driving would not occur using a drilled shaft. The drilled shaft method involves drilling below the surface with a rotating auger creating a hole whereby the supports can either be installed directly into the bored hole or supports fabricated off-site can be inserted into the hole.


  1. 9. There are DOTD and unmarked vehicles near my house and people are walking around under I-10 and close to my property. What are they doing?
    1. Starting in January 2018, LA DOTD began surveying the entire project corridor.  Various surveying activities will be taking place through December of 2018. Consultants working for the department are also out in the project corridor conducting environmental studies.


  1. 10. How can I find out the project plans and look at maps to see if my property will be affected?
    1. The “Project Info” tab on has links to the base concept maps from Stage 0. The project’s base concepts have not changed; therefore, these maps remain valid and a good source of project information. As the data develops, a round of public meetings will be held to present the new findings to the public.  We expect to hold the public meetings in the spring of 2018.


  1. 11. Is it true that the Perkins on/off ramps are being removed?
    1. The Perkins Road entrance and exit ramps are too close to the Acadian Thruway ramps. In order to lengthen the Acadian westbound on-ramp and the eastbound off-ramp, the Perkins ramps must be removed. Further, the removal of the Perkins ramps will allow a widened I-10 to fit largely within existing right-of-way thus limiting impacts to nearby businesses.


  1. 12. When will the environmental study be finished?
    1. A draft of the environmental study is scheduled to be released this summer for public comment. The final environmental study is anticipated to be completed by December 2018.


  1. 13. Is there a plan for where construction would begin first?
    1. DOTD is currently identifying project phases that could be independently constructed while keeping I-10 open to traffic. The recommended sequence of those construction phases is included in a Project Management Plan document that is completed after the environmental study.
