You mean the Mid-Town Springfield development that was abandoned. The Springfield Mall redevelopment is going full blast. Midtown plans where abandoned because the Springfield Mall was bought by Vornodo and they were going to build bigger and better so the developer bailed, but they still own the land.
Vornado has a permit in process for "Entire Demo" for a portion of the
mall. Demo location looks like it is in the area of and including
Macys.
They also just submitted plans to Fairfax concerning their plans.
