The Nevada Department of Transportation is working this weekend on westbound Interstate 80's major pothole damage from the flooding and snow earlier this month. Today, and almost certainly tomorrow, only one lane of traffic is getting by on westbound 80 from Wells all the way to Robb. Sandy reports this has caused significant delays, so you may want to avoid westbound 80 altogether when coming to the Cathedral tomorrow afternoon. (ETA Sunday, 1/29: It actually looks like they are NOT setting up for that work today, so you should be fine. Watch for potholes just the same; they're all over the metro area.)
There's no word yet on when NDOT will turn to the eastbound lanes.
