From the Texas Department of Transportation:
Both westbound lanes of I-20 at the US 84 overpass under construction in Nolan County are currently closed due to an overnight wreck.
Traffic should exit at US 84 Business to go around the closure and then re-enter westbound I-20. The closure is expected to last for several hours.
Crews will inspect the bridge construction thoroughly, but it appears that if any damage to the structure resulted from the crash, it is minor.
