I drove 385 between Arlington and Collierville a couple of hours ago.
As near as I can tell, re-signing work is complete on the highway itself: The 385 reference markers and reassurance shields are gone; 269 reference markers and reassurance shields are up, and exit numbers have been posted. The only signs I'm unsure of were the attractions/services signs which still read "Next Exit" rather than "Exit ##"...but I don't remember the contract calling for those to be changed.
On Eastbound I-40, the 1 mile advance sign has not been changed (although there are stakes in place which I assume are indications of work to be done by the contractor), but signs at the interchange itself are as specified in the contract.
The little bit of signage I could see from 385 on cross-roads at interchanges still showed 385.
No pictures, unfortunately. Besides the issues of not wanting to shoot photos while driving, the phone was down to 25% charge, and Idecided to power down until I got to the airport and needed it for boarding pass duty.
