Improving Mobility and Safety for Freight Operators and Passenger Vehicles in Georgia

The I-75 Commercial Vehicle Lanes


The Project

Vaughn & Melton was contracted by the Georgia Department of Transportation (GDOT) to oversee the surveying project for the construction of two, barrier-separated, northbound truck-only lanes approximately 41 miles in length along the I-75 corridor.


The I-75 Commercial Vehicle Lanes project will improve mobility and safety for freight operators and passenger vehicles. The new lanes will be non-tolled and will span across five counties: Henry, Spalding, Butts, Lamar, and Monroe. The I-75 Commercial Vehicle Lanes modernizes freight infrastructure and operations to grow the economy, increase competitiveness, and improve quality of life.


As the lead surveyor, Vaughn & Melton provided survey control for the 41 mile corridor and managed the Lidar mapping provided by Platinum Geomatics and the field enhancement surveys. Bridge scanning was also used to capture the bridges along the corridor.



The Work


Vaughn & Melton was tasked to provide all project primary control to all survey firms involved. Vaughn & Melton also provided QA/QC for the mapping and surveying firms. This was the first GDOT job to be processed through the 3D modeling software, Open Roads. All prior work for GDOT had been provided in an InRoads format. This was challenging as we found numerous issues with the new workspace and the processing as the libraries were not complete. V&M coordinated with GDOT and Bentley, the makers of Open Roads, documenting the issues and proposing solutions that have since been implemented by GDOT. Vaughn & Melton ultimately compiled all mapping and field data, processed it in Open Roads, and provided the deliverables to the lead contractor for their use in building concepts and costing plans for the future Design-Build project.
