The Virginia Department of Transportation plans to restore the left turn from Fair Lakes Parkway onto Fairfax County Parkway on Thursday, as the construction of a major new interchange in that area advances.

The turn has been blocked since July because of the work zone. As the new traffic pattern is set up, watch for delays on Fair Lakes Parkway from 9 p.m. Wednesday through 5 a.m. Thursday.

The entire $69.5 million project is scheduled for completion in 2013. When it is complete, local and parkway traffic will be separate, walkers and cyclists will have better access through the area, and more than three lanes of the Fairfax County Parkway will have been widened.
