Was browsing and came across this official-looking site for the I40 Crosstown relocation:

From the latest Google Earth imagery it looks like most bridgework is done with overpasses and bridges. Only the freeway itself isn't there yet.
There is new recent Google Earth imagery. The imagery date is October 13th, 2011. Works seem pretty advanced.
Anyone have good driving video of the 'old' route?
