A new traffic signal improvement project is scheduled to begin the week of January 12, 2009 to upgrade the intersections in the Marietta Square including Cherokee Street at Lawrence Street, Mill Street at Church Street, Whitlock Avenue at Old Powder Springs Street, and Roswell Street at Atlanta Street.
The upgrades will include new black ornamental traffic poles, decorative bases and mast arms with special downtown signage and wireless signal communication. All old traffic signals will be replaced with new LED (light emitting diodes) to increase visibility and decrease the amount of energy required to operate the signals.

Here are some reasons that LED traffic lights are better than conventional traffic signals:
- LEDs are brighter. The LED arrays fill the entire “hole” and have equal brightness across the entire surface, making them brighter overall.
- LED bulbs last for years, while halogen bulbs last for months. Replacing bulbs costs money for the trucks and people who do the work, and it also ties up traffic. Increasing the replacement interval can save a city big dollars.
- LED bulbs save a lot of energy.
To improve safety in and around the pedestrian areas, new street signage will be placed on the mast arms for increased visibility while providing a consistent image of the downtown and further enhancing the historic image of the Square. Implementation of the new traffic signal improvement project is expected to be completed in May of 2009.
Additional improvements to the Square will begin later this year and include repaving of road surfaces. Crosswalks and pedestrian areas will also be enhanced. Replacement of the aged traffic poles and signals will be an on-going project throughout Marietta. As the city removes the old poles, they will be refurbished and restored with a new longer-lasting baked-on paint and then reused at other intersections in the city for a consistent look around Marietta and to save taxpayer money.
