If you’ve driven down Interstate 277 or Independence Boulevard lately, you’ve probably seen them: small white squares right in the middle of the lane.
Turns out they’re not paint, but a semi-permanent tape, according to the N.C. Department of Transportation.
They are survey panels used to collect data about the roads, including the layout and surface. The panels do not collect traffic counts, department spokeswoman Jordan-Ashley Walker said.
Right now, the ones in Charlotte are not being used for any particular project. Instead, they inform the department about potential future needs for repaving or redesign.
“Essentially, it’s an alternative to the more traditional surveying procedures,” Walker said.
