After much trial and error, several different laser devices, and countless batteries, a grading crew in Ranger’s North Division has developed an accurate, laser-assisted grade-checking device that has proved its usefulness in real-world conditions.
Project Superintendent Ponch Frank said the device has saved both time and money on an I-95 widening project in St. Johns County. The job involved building 27 lane-miles of new roadway.
The grade-checking device is now in use on a similar widening job in Volusia County, which involves 11 lane-miles of new highway construction.
