The Transform 285/400 project is a major interchange reconstruction project with the bonus of collector-distributor lanes*  on both SR 400 and I-285 and various bridge improvements throughout the project limits. One of the bridge improvements includes widening and lengthening the Mount Vernon Highway bridge over SR 400.


The new bridge will widen the current two-lane bridge to a four-lane bridge with a median, bike lanes, and sidewalks.

What to Expect Next?

Construction of the new bridge will take place in three phases. 
•    Phase 1: Construction on the north side of the bridge. 
•    Phase 2: After the north half of the bridge is complete, traffic will switch to the new bridge. Crews will begin demolishing the old bridge.
•    Phase 3: Crews will construct the south side of the bridge next to the new north section. The bridge is expected to be completed in the first quarter of 2020.  

The bridge will remain open throughout construction and pedestrian access will be maintained. Motorists should expect nightly lane closures on Mount Vernon Highway and SR 400 with periodic daytime lane and shoulder closures. 

If you have questions about the Mount Vernon Highway bridge replacement or any other aspect of the Transform 285/400 project, please contact the project team through email, transform285400@dot.ga.gov, or call (404)-609-4609.

Note: all dates are subject to change 

   

 

Five Things You Need to Know:

  1. Contractors will widen Mount Vernon Highway bridge from two to four lanes.
  2. The new lanes on the north side will be built alongside the existing bridge. Later, traffic will shift to the new bridge and the southern side of the bridge will be constructed.
  3. A new median will separate the lanes on Mount Vernon Highway from Barfield Road to Crestline Parkway.
  4. The bridge will remain open with periodic daytime and nighttime closures on Mount Vernon Highway and SR 400.
  5. Pedestrian access will be maintained throughout construction and the new bridge will have 10-foot wide sidewalks on each side and five-foot-wide bike lanes.
