Transform 285/400: New Exit Opening at I-285 Westbound to SR 400 Northbound and Southbound

Weather permitting, Georgia Department of Transportation construction partners will shift traffic to a new exiting pattern from I-285 westbound to SR 400 northbound and southbound. Motorists will merge onto Collector-Distributer (CD) lanes near Ashford Dunwoody Road (current exiting pattern to Peachtree Dunwoody Road) to access the new configuration.

WHEN:  Starting Monday, August 8 at 5 a.m.
Dates may change due to weather or other factors

WHERE:  I-285 westbound to SR 400 northbound & southbound

The right lane will allow motorists to exit onto Peachtree Dunwoody Road and left lanes to exit to SR 400 northbound or southbound.

The Latest Updates on the Transform 285/400 Project

Anyone who has driven on or near the I-285/SR 400 interchange in recent months has likely seen shifted lanes, new traffic patterns, and other signs of construction. If you’ve been wondering what’s happening in that area and what driving conditions you can expect in the near future, read on for updates on the Transform 285/400 construction project.

Improvements on 285/400 Interchange Enhance Access, Safety for Travelers

The goals of Transform 285/400 are to reduce congestion, improve mobility, and enhance safety around the I-285/SR 400 interchange.

The Georgia Department of Transportation is tackling a number of projects that address these goals. For example, some exit ramps are being moved to encourage drivers to exit sooner, which is expected to ease traffic on the highways and, some cases, to encourage drivers to stay on local roads instead of taking the highway. New ramps and flyover bridges have been constructed as well.

The project also includes construction of new collector-distributor lanes. These lanes will help ease congestion by keeping entering and exiting traffic separated from mainline traffic.

Finally, the project is modernizing infrastructure in the area, with several brand new bridges, as well as a new type of interchange called a “diverging diamond” where Abernathy Road meets SR 400.

What’s Next?

Transform 285/400 has already accomplished a lot, and more improvements are on the way. Here’s an overview of what you can expect from Transform 285/400 in the near future.

The Main Lanes of SR 400 Over Abernathy Road Are Reopening

One of the goals of Transform 285/400 is replacing the SR 400 bridge over Abernathy Road. In order to do work on that bridge, traffic needed to be diverted to collector-distributor lanes instead of the main lanes of the route.

However, construction on that bridge is finishing up. As of recent weeks, traffic on the northbound side is back to its normal lanes and traveling on the new bridge. Work on the southbound side is expected to be completed this month. 

The Abernathy Diverging Diamond Will Open End of 2022

The diverging diamond being constructed at the interchange between SR 400 and Abernathy Road is set to open in Q4 of this year. This innovative type of freeway exchange helps reduce traffic congestion and make the interchange safer to drive through.

All Lanes on Mt. Vernon Bridge Are Now Open

Construction on the new Mt. Vernon Highway bridge over SR 400 is now complete. As of this month, all lanes on the bridge are open to drivers.

Lane Closures on I-285 Upcoming

In a few weeks, Transform 285/400 will enter one of its most significant phases as I-285 bridges over Glenridge Drive, SR 400, and Peachtree Dunwoody Road all get rebuilt.

In order for that to happen, though, some lane closures will have to occur. The two left-most lanes in both directions will be closed from Roswell Road to Ashwood Dunwoody Road. To ease the delays that this will cause, there are plans in place for some traffic to be diverted to the route’s collector-distributor lanes. 

If your commute regularly takes you over this part of the road, you may want to find an alternate route for the duration of the lane closures.            

Primary Construction Expected to Be Complete by Mid-2023

Much of the work for Transform 285/400 has been done, and the majority of the construction is expected to be complete by mid-2023. Of course, that doesn’t mean motorists have to wait a year to enjoy the benefits of the project. The roads, bridges, and collector-distributor lanes being worked on will open as they’re completed for Atlanta drivers to enjoy.

Construction is steadily advancing toward the goal of making the I-258/SR 400 interchange safer and less congested. For more information on the project, you can visit the project website.

Transform 285/400: Weekend Closure of I-285 Westbound to SR 400 Northbound and Southbound

Weather permitting, Georgia Department of Transportation construction partners will close the current I-285 westbound to State Route (SR) 400 northbound and southbound exit area for an entire weekend. The anticipated result of this continuous closure period is a new exiting pattern from I-285 westbound to SR 400 northbound and southbound opening Monday, Aug. 1. 

WHEN: Starting Friday, July 29 at 9 p.m. to Monday, Aug. 1 at 5 a.m.
 

Dates may change due to weather or other factors.

Transform 285/400: New Bridge Opening for I-285 Eastbound Exit to SR 400 Northbound 

Weather permitting, Georgia Department of Transportation construction partners will shift traffic onto a new bridge carrying I-285 eastbound motorists exiting to State Route (SR) 400 northbound. This pattern change removes the current left-hand merge maneuver and places drivers into the collector-distributor lanes to continue onto SR 400 northbound just past Abernathy Road. 

Opening by Monday, July 18 at 5 a.m.

Motorists will utilize the current exit point for SR 400 northbound from I-285 eastbound to shift onto the new configuration. The I-285 eastbound exit to SR 400 southbound will remain the same.

Transform 285/400 Interchange Closures: Summer Look Ahead!

Construction is heating up for the Transform 285/400 project! We have several traffic shifts planned for the coming months that include the opening of newly constructed bridges as motorists continue seeing benefits from roadway improvements.

The Transform 285/400 project will continue to enhance safety by reducing traffic on mainline I-285 and SR 400 through the implementation of new traffic shifts and the use of collector-distributor (CD) lanes to connect local exits. 

In the coming weeks, motorists traveling eastbound on I-285 will use Exit 25 to enter the CD lanes to access Roswell Road, Glenridge Drive and SR 400 northbound and southbound. 

Other traffic shifts happening this summer include moving traffic on SR 400 northbound and southbound back onto the mainlines from the CD lanes. The SR 400 northbound shift occurred on June 27.  The southbound shift is scheduled for later in July. There will also be a new exiting pattern from SR 400 northbound to Abernathy Road opening soon. 

Noise Barrier Update 

Noise barrier work will continue along the Transform 285/400 project throughout August. The work remaining for noise barriers includes not only the installation of the remaining post and panels, but also painting, installing doors, and flashing as well as final grading and the installation of concrete ditches. For this work to be completed along the noise barriers there will be a few sections with missing panels to allow workers to gain access behind the barrier. In certain areas the noise barriers remain open due to bridge construction needing to be finished before the completion of the noise barrier. 

Check out the updated noise barrier construction schedule/maps for both I-285 and SR 400. 

Mount Vernon Hwy Update 

The Transform 285/400 project developed a plan to demolish the existing bridge and build a new, four-lane bridge to better accommodate the increasing traffic on Mount Vernon Highway. The demolition of the prior bridge is complete and construction of the second half of the new bridge is coming to an end. The work remaining includes roadway tie-ins to the bridge, utility work, and widening to incorporate the two lanes in eastbound and westbound directions.

This shift will start from south of Hammond Drive to north of Abernathy Road.
