Is the closure of Fifth Avenue coming?

From the latest Atlantic Yards Construction Update, Weeks beginning November 23 and November 30:

The traffic and pedestrian safety barriers along the north side of Flatbush Avenue and Block 1118 for sewer installation is complete for the current phase of the work. Additional protection will be installed to modify traffic in 5th Avenue upon approval from the Department of Transportation.

The Department of Transportation first tried to close Fifth Avenue in May 2007, planning to revise service on the northbound B63 bus route.
