Latest update from STP Engineering:

No issues in right of ways purchases as it stands now. The final plans are about 60% final. St. Tammany is still waiting on DOTD to make comments on new traffic information submitted so they can proceed with additional study information on the roundabouts that DOTD has requested. The pipeline companies have all been notified and signed agreements with the Parish as well. Overall things are moving smoothly.
