Four new lanes of McGinnis Ferry Road across I-85 will open for traffic Tuesday, according to the Georgia Department of Transportation.

The extension of McGinnis Ferry from Satellite Boulevard to Lawrenceville Suwanee Road will open by mid-morning Tuesday, weather permitting. The 2.7-mile extension cost $20.4 million.

GDOT officials say the project, paid for with federal stimulus dollars, should provide congestion relief on I-85. In addition to the new lanes, the project includes new traffic signals at Old Peachtree Road and Lawrenceville Suwanee Road.
