I just checked the highway cameras and it looks like it's safe to to use 121/183 in Northeast Tarrant County for your post-work drive home. Texas Department of Transportation spokesman Val Lopez says the work crews at this very moment are finishing up the day's seal coating on 121/183 shoulders.
I checked the still images from the cameras and don't see the crews out there anymore. Looks to me like all lanes are open in all directions. (Watch for the usual mess at the 121/183 merge in Bedford, though. It's already gummed up there, and will probably stay that way 'til 7-ish)
Several people have asked why TxDot decided to close lanes during the work week. Val said the work was supposed to be done Saturday, but was postponed by rain.
