The Grayson City Council approved $23,000 Monday to purchase a traffic light mast arm at Grayson Parkway and Rosebud Road.

The traffic arm will match others already in place in the city. In addition, the city council authorized Mayor Allison Wilkerson to sign a right-of-way negotiation with Gwinnett County Commissioners for improvements at the same intersection.

Gwinnett DOT will start on improvements for this intersection beginning in January and construction is expected to take six to nine months. Enhancements will include left turn signals from all four directions.
