A $5.6m project to replace 42 interstate message boards with new eco- and user-friendly signs has begun in the US state of Georgia.

The old message boards on some of the interstates will be removed, as part of the department of transportation’s move to upgrade its technology and provide drivers with real-time traffic information.

The messages will be written in LED lights, which have a longer burn time, consume less energy and ensure better visibility in conditions of low light due to rain or snow, according to gwinnettdailypost.com.

Georgia-based SERVO and World Fiber Technologies started work on Interstate 85 this week and the project is set to be completed next year.
