Georgia Department of Transportation contractors will close the left lane of Interstate 285 onto State Route 400 this weekend, weather permitting.

At 8 p.m. Friday one left lane will be closed on the westbound side of I-285 from Ashford Dunwoody Road to Long Island Drive until 6 a.m. Saturday. The lane closures are for construction work on the construction of the Transform 285/400 interchange project.

The project will reduce traffic congestion and enhance safety in the area near the I-285/State Route 400 interchange, adding flyover ramps and collector-distributor lanes. The project will improve 4.3 miles of I-285 from west of Roswell Road to east of Ashford Dunwoody Road and 6.2 miles along SR 400 from the Glenridge Connector to Spalding Drive.

The project is expected to be completed in 2020 and is expected to generate cost savings of approximately $300 million.
