HOUSTON — UPDATE: The scene has been cleared and traffic is back to normal.
There's a big mess causing delays on the Gulf Freeway early Friday where a major crash was reported before sunrise.
Views from Air 11 showed a truck on its side with wet concrete spilled all over the road near Griggs.
All southbound lanes are blocked just inside the 610 South Loop, and northbound lanes are slow as well due to rubbernecking:
The crash happened at about 5 a.m. Friday. The backup was still ongoing as of 9:50 a.m.
Drivers are advised to avoid the area for the next few hours.
Police did not immediately release details about the wreck, although it was listed as a hit-and-run. The condition of the truck's driver is not known at this time.
