DOTD to begin LiDAR scanning along I-10 in Orleans Parish

New Orleans, La. - The Louisiana Department of Transportation and Development announces that motorists may see slow moving traffic during non-peak hours along portions of I-10 in Orleans Parish on January 30. Survey work is scheduled for that day as part of the mill and overlay project scheduled at I-10 from Paris Road to Lake Pontchartrain in the New Orleans region.

Crews will be traveling along I-10 from I-510 (Paris Road) to the west end of the Twin Spans over Lake Pontchartrain. Both east and west bound lanes will be surveyed using Mobile Light Detection and Ranging (LiDAR) technology. LiDAR scanning is a surveying method used to measure distance by using laser lights that make digital 3-D representations of the intended target.

This activity will not have any lane closures associated with it, however, it will cause traffic to slow down due to police blocking traffic, similar to a funeral procession. The mobile LiDAR scanning will continue through the week, driving along the surface streets and interstate along the vicinity of this project.

The Mobile LiDAR method is extremely cost beneficial to the state, as it will assist in expediting the Topography survey delivery schedule for DOTD designers, prevents multiple lane closures throughout the corridor, and reduce the number of conventional survey crews needed to perform the survey. DOTD has used this technology in previous projects throughout the state, and it has been proven to be a useful tool in the Topography Survey Process.

Surveying is weather dependent and will be performed during the day between peak hours from approximately 9 a.m. to 3 p.m.
